The Magnesium Micronutrient RBC Test measures magnesium levels within red blood cells, providing a more accurate assessment of long-term magnesium status than serum tests. Magnesium is vital for muscle and nerve function, energy production, bone strength, and heart health. This test helps detect deficiencies or imbalances from poor diet, absorption issues, or medical conditions, supporting overall wellness.

Patient must be 18 years of age or older.

The Magnesium test measures the levels of magnesium, an essential mineral, in the blood. Magnesium is involved in numerous bodily functions, including nerve and muscle function, regulating blood pressure, and maintaining a healthy heart rhythm.

: Serum
Also Known As: Mg Test, Mag Test

 The Magnesium 24-Hour Urine with Creatinine test measures the amount of magnesium excreted in the urine over a 24-hour period, along with the amount of creatinine. Magnesium, an essential mineral, plays a critical role in various biochemical processes, including energy production, muscle function, nerve function, and bone development. Creatinine is a waste product that the muscles produce at a constant rate, and its levels help gauge kidney function and validate the completeness of the 24-hour urine collection.

Also Known As: BMP Test, Chemistry Panel, Chemistry Screen, Chem 7, Chem 11, SMA 7, SMAC7, Basic Metabolic Test, Chem Test, Chem Panel Test 

The Calcium Micronutrient Test measures calcium levels in the blood to assess nutritional status and detect imbalances. Calcium is essential for strong bones and teeth, muscle contraction, nerve signaling, and heart function. This test helps identify deficiencies, excess, or issues with absorption and metabolism, supporting diagnosis and management of bone health, hormonal balance, and overall wellness.

Patient must be 18 years of age or older.
: Serum
Also Known As: Ca Test, Serum Calcium Test, Calcium Blood Test

Most Popular

The Calcium Test measures calcium levels in the blood to help evaluate bone health, nerve and muscle function, and heart activity. Abnormal levels may indicate issues with the parathyroid glands, kidneys, bones, or nutritional balance.

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

The Heavy Metals Micronutrients Blood Test Panel measures levels of arsenic, cadmium, cobalt, lead, and mercury to assess exposure and potential toxicity. These metals, found in the environment, food, or workplaces, can affect the nervous system, kidneys, bones, and overall health. This panel helps detect harmful accumulation, guide treatment, and monitor risks from environmental or occupational exposure.

Patient must be 18 years of age or older.

The Calcium Ionized Test measures the level of free, active calcium in the blood that is not bound to proteins. Ionized calcium is vital for muscle contraction, nerve function, and heart health. This test helps evaluate calcium balance, diagnose parathyroid or kidney disorders, and monitor critically ill patients.

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

The Ceruloplasmin Test measures the level of ceruloplasmin, a protein that carries copper in the blood. It helps evaluate copper metabolism and diagnose conditions such as Wilson’s disease, Menkes disease, or copper deficiency. Abnormal levels may also indicate liver disease or other metabolic disorders.

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

The Complete Blood Count (CBC) with Differential and Platelets test measures red and white blood cells, hemoglobin, hematocrit, platelets, and white cell types. It helps detect infections, anemia, inflammation, immune disorders, and blood cancers, and assesses oxygen delivery, immunity, and clotting.

CBC, Complete Blood Count, Complete Blood Cell Count, Blood Count, Hemogram, CBC with Differential, CBC w/ Diff, CBC with Automated Differential, CBC Auto Diff, CBC with Manual Differential, CBC without Differential, CBC No Diff


The Comprehensive Metabolic Panel (CMP) measures blood sugar, electrolytes, kidney and liver function, and protein levels to assess metabolic health and organ function. It’s used in routine screenings, to monitor chronic conditions, and to detect potential health issues early.

: Serum
Also Known As: CMP Test, Chemistry Panel Test, Chem Test, Chem 21 Test, Chem 14 Test 

The Copper Micronutrient Plasma Test measures copper levels in the blood to evaluate nutritional status and detect deficiencies or excess. Copper is essential for red blood cell formation, connective tissue health, energy production, and nervous and immune system function. This test helps identify imbalances from poor diet, malabsorption, or toxicity, supporting diagnosis and management of overall health.

Patient must be 18 years of age or older.
