The ionized calcium is determined by an ion selective electrode methodology. The result that is generated is pH adjusted. The result is empirically based on a measured pH and ionized calcium concentration normalized to a pH of 7.40. This calculation compensates for in vitro changes in pH due to loss of CO2 through specimen handling. Ionized calcium represents the true "bioavailable" calcium in the circulation. In situations where the total calcium is normal but does not fit the clinical picture, e.g., hyperparathyroidism, a determination of the ionized calcium will, many times, show an elevation in the "bioavailable" calcium component. This may be due to alterations in protein concentrations, especially albumin, that binds most of the calcium in the circulation.

Decreased levels of ceruloplasmin are found in Wilson''s Disease, fulminant liver failure, intestinal malabsorption, renal failure resulting in proteinuria, chronic active hepatitis and malnutrition. Elevated levels are found in primary biliary cirrhosis, pregnancy (first trimester), oral contraceptive use and in acute inflammatory conditions since ceruloplasmin is an acute phase reactant

A Complete Blood Count (CBC) Panel is used as a screening test for various disease states including anemia, leukemia and inflammatory processes.

A CBC blood test includes the following biomarkers: WBC, RBC, Hemoglobin, Hematocrit, MCV, MCH, MCHC, RDW, Platelet count, Neutrophils, Lymphs, Monocytes, Eos, Basos, Neutrophils (Absolute), Lymphs (Absolute), Monocytes(Absolute), Eos (Absolute), Basos (Absolute), Immature Granulocytes, Immature Grans (Abs)

Copper is an essential element that is a cofactor of many enzymes. Copper metabolism is disturbed in Wilson's disease, Menkes disease, primary biliary cirrhosis, and Indian childhood cirrhosis. Copper concentrations increase in acute phase reactions and during the third trimester of pregnancy. Copper concentrations are decreased with nephrosis, malabsorption, and malnutrition. Copper concentrations are also useful to monitor patients, especially preterm newborns, on nutritional supplementation. Results of copper are often interpreted together with ceruloplasmin.

Usual method for determining anemia. Used to calculate indices.

Serum iron quantification is useful in confirming the diagnosis of iron-deficiency anemia or hemochromatosis. The measurement of total iron binding in the same specimen may facilitate the clinician''s ability to distinguish between low serum iron levels caused by iron deficiency from those related to inflammatory neoplastic disorders. The assay for iron measures the amount of iron which is bound to transferrin. The total iron binding capacity (TIBC) measures the amount of iron that would appear in blood if all the transferrin were saturated with iron. It is an indirect measurement of transferri

Vitamin A is critical for vision, growth, and many cell functions. High concentrations of vitamin A are seen with renal failure, but this is not associated with toxicity, and excessive ingestion. High concentrations are associated with bone fractures. Low concentrations of vitamin A are consistent with fat malabsorption and rarely due to inadequate diet. Vitamin A, vitamin E, and carotene are always extracted and detected simultaneously. This is a free vitamin A (retinol

This test is used to measure the bio-active form of Vitamin D. This test is also used in the differential diagnosis of hypocalcemia and to monitor patients with renal osteodystrophy or chronic renal failure.

Measurement of serum 25-OH vitamin D concentrations provide a good index of circulating vitamin D activity in patients not suffering from renal disease. Lower than normal 25-OH vitamin D levels can result from a dietary deficiency, poor absorption of the vitamin or impaired metabolism of the sterol in the liver. A 25-OH vitamin D deficiency can lead to bone diseases such as rickets and osteomalacia. Above normal levels can lead hypercalcemia. This assay employs liquid chromatography tandem mass spectrometry to independently measure and report the two common forms of 25-hydroxy vitamin D: 25OH D3 - the endogenous form of the vitamin and 25OH D2 - the analog form used to treat 25OH Vitamin D3 deficiency.

Zinc is an essential element involved in a myriad of enzyme systems including wound healing, immune function, and fetal development. Zinc measurements are used to detect and monitor industrial, dietary, and accidental exposure to zinc. Also, zinc measurements may be used to evaluate health and monitor response to treatment.



How often do you think about your mineral levels? 

Unless you're a professional athlete, doctor, or nutritionist, it probably doesn't cross your mind more than once a year at your annual physical. If you're taking a multivitamin, that's even better than most!

Magnesium is crucial to the body's muscle, hormonal, and nerve function. Without it, you're likely feeling tired, crampy, and anxious. You may have a hard time focusing and struggle to sleep, digest meals, or enjoy sex. 

Magnesium blood tests are the first look into what your body may be lacking. Read on to understand how magnesium deficiency feels and how the correct magnesium deficiency test can start you on the right track to functional healing.   

Risk Factors For Magnesium Deficiency 

Some populations are at a higher risk for magnesium deficiency. These include: 

  • Diabetics
  • Those with an unhealthy diet 
  • Pregnant women
  • Those taking medications that inhibit magnesium stores in the body 
  • Those with vitamin D deficiency 
  • Those with gastrointestinal conditions
  • Alcoholics

If you fall under any of these groups, it might be worth getting tested.  

Causes of Magnesium Deficiency 

Magnesium deficiency is caused by the body's inability to properly absorb the mineral in the gut or excess magnesium loss through the body's waste. In addition, kidney problems may affect magnesium excretion, as it is the kidney's responsibility to determine optimal levels in the body. 

Magnesium levels are also known to take a hit during pregnancy.  

Nutrition lacking in essential vitamins and minerals may also affect magnesium levels. 

Signs and Symptoms of Magnesium Deficiency

Magnesium is a metabolic necessity in our bodies. It's needed in optimal amounts for your bones, muscles, nerves, digestive tract, hormones, blood sugar, and heart. 

Magnesium deficiency can range from barely noticeable to extremely uncomfortable. Signs and symptoms of magnesium deficiency include: 

  • Muscle cramping
  • Depression and anxiety 
  • Osteoporosis 
  • Fatigue and poor sleep 
  • High blood pressure and heart arrhythmia 
  • Poor appetite
  • Nausea 
  • Weakness 
  • Headaches
  • Low levels of other minerals - like calcium and potassium 

Having any one of a few of these symptoms may not necessarily point to a deficiency. It will take a lab test to determine if you are. 

Lab Tests for Magnesium Deficiency  

Your doctor will require a magnesium deficiency lab test to screen, diagnose and monitor your condition. To confirm that you are magnesium deficient, a doctor may request a urine sample, though a blood test is most efficient. 

A magnesium deficiency test is also known as a serum magnesium test. Its purpose is to measure the amount of magnesium in the blood–-though a majority of the body's magnesium stores are found in the bones. 

You can initiate your blood draw from one of 2,100 state and federally certified blood-draw centers near your home. Once your specimen is collected, it is sent to Quest Diagnostics to process, and your results will be available for you to view on your Ulta Lab Tests dashboard.

An optimal blood (serum) magnesium level is is 1.8 to 2.2 milligrams per deciliter (mg/dL). Anything lower than this range may be diagnosed by your doctor as hypomagnesemia and will need an immediate treatment plan.

  • Magnesium citrate - extremely bioavailable source of magnesium naturally found in citrus fruits and supplements
  • Magnesium oxide - not typically used for magnesium deficiencies, but valuable for soothing digestive symptoms  
  • Magnesium chloride - easily absorbed in the digestive system and used for treating low magnesium levels, heartburn, and constipation
  • Magnesium lactate - often taken by those who need high levels of magnesium 
  • Magnesium malate - a gentle supplemental form of magnesium 
  • Magnesium taurate - supports healthy blood pressure 
  • Magnesium L-threonate - known for increasing magnesium levels in brain cells
