Description: A Calcium test is a blood test that is used to screen for, diagnose, and monitor a wide range of medical conditions.

Also Known As: Ca Test, Serum Calcium Test, Calcium Blood Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a Calcium test ordered?

A blood calcium test is frequently requested during a general medical evaluation. It's usually part of the comprehensive metabolic panel or the basic metabolic panel, two sets of tests that can be done during an initial evaluation or as part of a routine medical checks.

Many people do not experience symptoms of high or low calcium until their levels are dangerously high or low.

When a person has certain types of cancer, kidney illness, or has had a kidney transplant, calcium monitoring may be required. When someone is being treated for abnormal calcium levels, monitoring may be required to determine the effectiveness of medications such as calcium or vitamin D supplements.

What does a Calcium blood test check for?

Calcium is one of the most plentiful and vital minerals in the human body. It is required for cell signaling as well as the proper operation of muscles, nerves, and the heart. Calcium is essential for blood clotting as well as bone growth, density, and maintenance. This test determines how much calcium is present in the blood.

Calcium is found complexed in the bones for 99 percent of the time, while the remaining 1% circulates in the blood. Calcium levels are closely monitored; if too little is absorbed or consumed, or if too much is lost through the kidney or stomach, calcium is removed from bone to keep blood concentrations stable. Approximately half of the calcium in the blood is metabolically active and "free." The other half is "bound" to albumin, with a minor proportion complexed to anions like phosphate, and both of these forms are metabolically inactive.

Blood calcium can be measured using two different tests. The free and bound forms of calcium are measured in the total calcium test. Only the free, physiologically active form of calcium is measured in the ionized calcium test.

Lab tests often ordered with a Calcium test:

  • Phosphorus
  • Vitamin D
  • Magnesium
  • PTH
  • Albumin
  • Basic Metabolic Panel (BMP)
  • Comprehensive Metabolic Panel (CMP)

Conditions where a Calcium test is recommended:

  • Kidney Disease
  • Thyroid Disease
  • Alcoholism
  • Malnutrition
  • Parathyroid Diseases
  • Breast Cancer
  • Multiple Myeloma

How does my health care provider use a Calcium test?

A blood calcium test is used to screen for, diagnose, and monitor a variety of bone, heart, nerve, kidney, and tooth disorders. If a person has signs of a parathyroid disease, malabsorption, or an overactive thyroid, the test may be ordered.

A total calcium level is frequently checked as part of a standard health check. It's part of the comprehensive metabolic panel and the basic metabolic panel, which are both collections of tests used to diagnose or monitor a range of ailments.

When a total calcium result is abnormal, it is interpreted as a sign of an underlying disease. Additional tests to assess ionized calcium, urine calcium, phosphorus, magnesium, vitamin D, parathyroid hormone, and PTH-related peptide are frequently performed to assist determine the underlying problem. PTH and vitamin D are in charge of keeping calcium levels in the blood within a narrow range of values.

Measuring calcium and PTH combined can assist identify whether the parathyroid glands are functioning normally if the calcium is abnormal. Testing for vitamin D, phosphorus, and/or magnesium can assist evaluate whether the kidneys are excreting the right amount of calcium, and measuring urine calcium can help detect whether additional deficits or excesses exist. The balance of these many compounds is frequently just as critical as their concentrations.

The total calcium test is the most common test used to determine calcium status. Because the balance between free and bound calcium is usually constant and predictable, it is a reliable reflection of the quantity of free calcium present in the blood in most cases. However, the balance between bound and free calcium is altered in some persons, and total calcium is not a good indicator of calcium status. Ionized calcium measurement may be required in certain cases. Critically sick patients, those receiving blood transfusions or intravenous fluids, patients undergoing major surgery, and persons with blood protein disorders such low albumin are all candidates for ionized calcium testing.

What do my Calcium test results mean?

The amount of calcium circulating in the blood is not the same as the amount of calcium in the bones.

A feedback loop including PTH and vitamin D regulates and stabilizes calcium uptake, utilization, and excretion. Conditions and disorders that disturb calcium control can induce abnormal acute or chronic calcium elevations or declines, resulting in hypercalcemia or hypocalcemia symptoms.

Total calcium is usually tested instead of ionized calcium since it is easier to do and requires no additional treatment of the blood sample. Because the free and bound forms of calcium make up about half of the total, total calcium is usually a decent depiction of free calcium. Because nearly half of the calcium in blood is bonded to protein, high or low protein levels might alter total calcium test findings. In these circumstances, an ionized calcium test is more appropriate for measuring free calcium.

A normal total or ionized calcium test, when combined with other normal laboratory findings, indicates that a person's calcium metabolism is normal and blood levels are properly managed.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.

Clinical Significance
Micronutrient, Calcium - Serum calcium is involved in the regulation of neuromuscular and enzyme activity, bone metabolism and blood coagulation. Calcium blood levels are controlled by a complex interaction of parathyroid hormone, vitamin D, calcitonin and adrenal cortical steroids. Calcium measurements are useful in the diagnosis of parathyroid disease, some bone disorders and chronic renal disease. A low level of calcium may result in tetany.

Patients must be 18 years of age or greater.

Description: A Vitamin D test is a blood test used to determine if you have a Vitamin D deficiency and to monitor Vitamin D levels if you are on supplementation.

Also Known As: Ergocalciferol Test, Vitamin D2 Test, Cholecalciferol Test, Vitamin D3 Test, Calcidiol Test, 25-hydroxyvitamin D Test, Calcifidiol Test, 25-hydroxy-vitamin D Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: Fasting preferred, but not required.

When is a Vitamin D test ordered:

When calcium levels are inadequate and/or a person exhibits symptoms of vitamin D deficiency, such as rickets in children and bone weakening, softness, or fracture in adults, 25-hydroxyvitamin D is frequently ordered to rule out a vitamin D deficit.

When a person is suspected of having a vitamin D deficiency, the test may be requested. Vitamin D deficiency is more common in older folks, people who are institutionalized or homebound and/or have minimal sun exposure, people who are obese, have had gastric bypass surgery, and/or have fat malabsorption. People with darker skin and breastfed babies are also included in this category.

Before starting osteoporosis medication, 25-hydroxyvitamin D is frequently requested.

What does a Vitamin D blood test check for?

Vitamin D is a group of chemicals that are necessary for the healthy development and growth of teeth and bones. The level of vitamin D in the blood is determined by this test.

Vitamin D is tested in the blood in two forms: 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D. The primary form of vitamin D found in the blood is 25-hydroxyvitamin D, which is a relatively inactive precursor to the active hormone 1,25-dihydroxyvitamin D. 25-hydroxyvitamin D is routinely evaluated to assess and monitor vitamin D status in humans due to its longer half-life and higher concentration.

Endogenous vitamin D is created in the skin when exposed to sunshine, whereas exogenous vitamin D is taken through foods and supplements. Vitamin D2 and vitamin D3 have somewhat different molecular structures. Fortified foods, as well as most vitamin preparations and supplements, include the D2 form. The type of vitamin D3 produced by the body is also used in some supplements. When the liver and kidneys convert vitamin D2 and D3 into the active form, 1,25-dihydroxyvitamin D, they are equally effective.

Some tests may not differentiate between the D2 and D3 forms of vitamin D and just report the total result. Newer methods, on the other hand, may record D2 and D3 levels separately and then sum them up to get a total level.

Vitamin D's major function is to assist balance calcium, phosphorus, and magnesium levels in the blood. Vitamin D is necessary for bone growth and health; without it, bones become fragile, misshapen, and unable to mend themselves properly, leading to disorders such as rickets in children and osteomalacia in adults. Vitamin D has also been proven to influence the growth and differentiation of a variety of other tissues, as well as to aid in immune system regulation. Other illnesses, such as autoimmune and cancer, have been linked to vitamin D's other roles.

According to the Centers for Disease Control and Prevention, two-thirds of the US population has adequate vitamin D, while one-quarter is at risk of inadequate vitamin D and 8% is at risk of insufficiency, as defined by the Institute of Medicine's Dietary Reference Intake.

The elderly or obese, persons who don't receive enough sun exposure, people with darker skin, and people who take certain drugs for lengthy periods of time are all at risk of insufficiency. Adequate sun exposure is usually defined as two intervals of 5-20 minutes each week. Vitamin D can be obtained through dietary sources or supplements by people who do not get enough sun exposure.

This test has 3 Biomarkers

  • Vitamin D Total which is a combined measurement of Vitamin D, 25-Oh, D2 and Vitamin 25-Oh, D3
  • Vitamin D, 25-Oh, D2 which is a measurement of ergocalciferol Vitamin D, which is Vitamin D obtained through plant sources. 
  • Vitamin D, 25-Oh, D3 which is a measurement of cholecalciferol Vitamin D, which is Vitamin D obtained through animal sources.

Lab tests often ordered with a Vitamin D test:

  • Complete Blood Count
  • CMP
  • Iron and TIBC
  • Calcium
  • Phosphorus
  • PTH
  • Magnesium

Conditions where a Vitamin D test is recommended:

  • Kidney Disease
  • Osteoporosis
  • Lymphoma
  • Cystic Fibrosis
  • Autoimmune Disorders
  • Celiac Disease
  • Malabsorption
  • Malnutrition

Commonly Asked Questions:

How does my health care provider use a Vitamin D test?

Determine whether a deficit or excess of vitamin D is causing bone weakening, deformity, or improper calcium metabolism.

Because PTH is required for vitamin D activation, it can aid in diagnosing or monitoring problems with parathyroid gland function.

Because vitamin D is a fat-soluble vitamin that is absorbed from the intestine like a fat, it can help monitor the health of people with conditions that interfere with fat absorption, such as cystic fibrosis and Crohn's disease.

People who have had gastric bypass surgery and may not be able to absorb adequate vitamin D should be closely monitored.

When vitamin D, calcium, phosphorus, and/or magnesium supplementation is suggested, it can help assess the success of the treatment.

What do my Vitamin D results result mean?

Despite the fact that vitamin D techniques differ, most laboratories use the same reference intervals. Because toxicity is uncommon, researchers have focused on the lower limit and what cut-off for total 25-hydroxyvitamin D shortage implies.

A low blood level of 25-hydroxyvitamin D could indicate that a person isn't getting enough sunlight or dietary vitamin D to meet his or her body's needs, or that there's an issue with absorption from the intestines. Seizure medications, notably phenytoin, might occasionally interfere with the liver's generation of 25-hydroxyvitamin D.

Vitamin D insufficiency has been linked to an increased risk of some malignancies, immunological illnesses, and cardiovascular disease.

Excessive supplementation with vitamin pills or other nutritional supplements frequently results in a high level of 25-hydroxyvitamin D.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.

Beta Carotene, a fat soluble nutrient, is a precursor to vitamin A. Deficiencies may lead to vitamin A deficiency. Excessive vitamin A intake may lead to headaches, loss of appetite, nausea and diarrhea, skin changes, and potential birth defects.

Description: Ceruloplasmin is a blood test that measures that amount of Ceruloplasmin in the blood’s serum. Ceruloplasmin, or Copper Oxide, is a protein that is created in the liver and is used to transport copper from the liver to the parts of the body that need it, including the blood.

Also Known As: Copper Oxide Test, Wilson’s Disease Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a Ceruloplasmin test ordered?

When somebody has symptoms that a health practitioner suspects are due to Wilson disease, a ceruloplasmin test may be ordered alone or in combination with blood and 24-hour urine copper testing.

What does a Ceruloplasmin blood test check for?

Ceruloplasmin is a copper-containing enzyme that aids in iron metabolism in the body. The level of ceruloplasmin in the blood is measured with this test.

Copper is a vital mineral that regulates iron metabolism, connective tissue creation, cellular energy production, and nervous system function. The intestines absorb it from meals and liquids, and it is subsequently transferred to the liver, where it is stored or used to make a variety of enzymes.

To make ceruloplasmin, the liver binds copper to a protein and then releases it into the bloodstream. Ceruloplasmin binds about 95 percent of the copper in the blood. As a result, the ceruloplasmin test can be performed in conjunction with one or more copper tests to assist diagnose Wilson disease, a genetic illness in which the liver, brain, and other organs store too much copper.

Lab tests often ordered with a Ceruloplasmin test:

  • Copper

Conditions where a Ceruloplasmin test is recommended:

  • Wilson’s Disease
  • Liver Diseases

How does my health care provider use a Ceruloplasmin test?

Wilson disease is a rare genetic ailment characterized by excessive copper accumulation in the liver, brain, and other organs, as well as low levels of ceruloplasmin. Ceruloplasmin testing is performed in conjunction with blood and/or urine copper assays to assist diagnosis Wilson disease.

Copper is a mineral that plays an important role in the human body. Ceruloplasmin binds about 95 percent of the copper in the blood. In an unbound state, just a minimal quantity of copper is present in the blood.

A ceruloplasmin test may be ordered in conjunction with a copper test to assist diagnose problems in copper metabolism, copper deficiency, or Menkes kinky hair syndrome, a rare genetic condition.

What do my Ceruloplasmin test results mean?

Ceruloplasmin levels are frequently tested in conjunction with copper testing because they are not indicative of a specific illness.

Wilson disease can be identified by low ceruloplasmin and blood copper levels, as well as high copper levels in the urine.

About 5% of persons with Wilson disease who have neurological symptoms, as well as up to 40% of those with hepatic symptoms, especially if they are critically unwell, will have normal ceruloplasmin levels.

The person tested may have a copper deficiency if ceruloplasmin, urine, and/or blood copper values are low.

Anything that affects the body's ability to metabolize copper or the supply of copper has the potential to impact blood ceruloplasmin and copper levels.

Serum chloride is the major extracellular anion and counter-balances the major cation, sodium, maintaining electrical neutrality of the body fluids. Two thirds of the total anion concentration in extracellular fluids is chloride and it is significantly involved in maintaining proper hydration and osmotic pressure. Movement of chloride ions across the red blood cell membrane is essential for the transport of biocarbonate ions in response to changing concentrations of carbon dioxide. Chloride measurements are used in the diagnosis and treatment of electrolyte and metabolic disorders such as cystic fibrosis and diabetic acidosis.

A vitamin test is simple, but it can be challenging to know which test you should choose and why. Read on for our vitamin test guide so you can make informed choices on the right test for you.

What Are Vitamin & Mineral Tests?

A balanced intake of vitamins and minerals generally comes from a healthy diet or supplements if there are dietary restrictions. These vitamins and minerals include the following:

  • Vitamins: A, C, D, E, and K
  • B vitamins: B1, B2, B3, B5, B6, and B12
  • Minerals: calcium, magnesium, iron, folate, and zinc

Vitamin and mineral tests use a sample of your blood to test for the levels of vitamins and minerals circulating in your body. A phlebotomist at an authorized patient service center will draw your blood and forward the specimen to a national laboratory for testing.

Once the specimen arrives at the lab, testing will begin, and results will post to your online patient portal within a couple of days as the lab completes testing.

Benefits of Vitamin & Mineral Lab Testing

Vitamins and minerals play a role in our bodies' functions, from bone density to brain functions. They’re also related to chronic diseases and health conditions, such as:

  • Osteoporosis
  • Diabetes
  • Hypertension
  • Heart disease
  • Autoimmune disease
  • Anemia
  • Depression
  • Bone loss

Most people don’t actively monitor their vitamin and mineral intake. A vitamin and mineral test determines if you have a deficiency or are at risk for developing one.

A vitamin deficiency can be an early warning sign you’re developing serious health issues. If caught early, many conditions like diabetes and anemia can be avoided. A fast response is always the best response.

Heart disease is the number one cause of death in the U.S. and the world. A healthy intake of essential vitamins and minerals can mitigate risk factors for heart disease.

Vitamin & Mineral Tests for Your Health

At Ulta Lab Tests, we offer four main vitamin and minerals blood tests:

The Vitamins & Minerals - Basic panel includes 4 tests and 6 biomarkers. This test looks for anemia. The serum folate markers ensure your recent diet is providing accurate results.

The Vitamins & Minerals - Basic Plus panel has 8 tests and 13 biomarkers. Along with anemia, it has a vitamin D test that can help determine if health issues like depression are related to a vitamin deficiency.

The Vitamins & Minerals - Advanced panel has 22 tests with 115 biomarkers. It tests for multiple deficiencies along with a urinalysis test for the levels of your white and red blood counts.

The Vitamins & Minerals - Comprehensive panel has 24 tests and 34 biomarkers. It offers a full range of testing for over twenty essential vitamins and minerals.

Depending on your symptoms, you may need only a basic panel or a urinalysis with a vitamin blood test. 

Frequently Asked Questions About Vitamin Tests

Getting a vitamin and mineral test is easy to do and comes with many benefits. You take active control of your health and ensure you get the necessary nutritional intake needed to prevent certain health issues from developing.

But you may still be unsure why a vitamin test is necessary if you eat plenty of food and don’t have dietary restrictions. Or you may not know what to do if it reveals a deficiency.

How Will a Vitamin Test Help You?

American diets are notoriously high in fat, sugar, and salt and low in nutritional value.

In our fast-paced workaholic culture, processed food and fast food is the norm. Millions of Americans even live in food deserts where healthy food is not accessible.

You may have mental and physical health symptoms without connecting them to a deficiency. Your symptoms can also mimic health issues you already know about.

FOR EXAMPLE, Vitamin D deficiency correlates with depression, and many of their symptoms (fatigue, body aches) are the same. Only a vitamin D blood test can reveal the underlying cause of your symptoms.

Other symptoms of vitamin deficiencies include:

  • Mood shifts
  • Personality changes
  • Insomnia
  • Muscle weakness or cramps
  • Dizziness and lightheadedness
  • Shortness of breath
  • Nausea and upset digestion

Even if you have access to plenty of food, it may not be the best quality for vitamin intake. It’s easy to develop a vitamin deficiency even in countries that have low rates of food insecurity.

Vitamin D deficiencies are especially prevalent. Almost every adult would benefit from a vitamin D test alone.

What Should You Do if Your Test Reveals a Deficiency?

Fortunately, low vitamin and mineral levels are usually easy to correct.

You might need to make minor adjustments to your diet or take vitamin and mineral supplements in most cases. Some doctors may even prescribe your supplements. You can get tested again a few months later to make sure the adjustments are working.

If your deficiency is a sign of serious health issues, a vitamin and mineral test will show what further specific tests are needed. A lack of vitamin absorption, even if you have a healthy intake, indicates a potential problem.

Both Chron's and celiac disease, for example, interfere with the absorption of B12. It’s important to understand your test results and what they could mean to your health.
