The Selenium RBC Test measures selenium levels inside red blood cells, providing a more accurate reflection of long-term selenium status than serum testing. Selenium is essential for antioxidant defense, thyroid function, and immune health. Abnormal results may indicate deficiency linked to fatigue, thyroid disorders, or poor immunity, or excess from supplementation. Doctors use this test to evaluate nutritional balance, guide treatment, and monitor metabolic health.

The Zinc RBC Test measures zinc levels inside red blood cells, providing a more accurate reflection of long-term zinc status than serum tests. Zinc is vital for immune defense, wound healing, growth, and enzyme function. Deficiency may cause hair loss, poor healing, or weakened immunity, while excess may be toxic. Doctors order this test to evaluate nutritional status, chronic illness, or suspected deficiency. Results guide supplementation and overall health management.

The Magnesium RBC Test measures magnesium inside red blood cells, providing a more accurate assessment of magnesium status than serum tests. Magnesium is vital for energy production, muscle and nerve function, heart rhythm, and bone health. Low levels may cause fatigue, cramps, arrhythmias, or weakness, while high levels may signal kidney issues. Doctors order this test to detect deficiency, monitor therapy, and evaluate overall metabolic and nutritional health.

The Potassium RBC Test measures potassium levels inside red blood cells, providing a more accurate assessment of long-term potassium status than serum testing. Potassium is essential for muscle contraction, heart rhythm, nerve signaling, and fluid balance. Abnormal results may indicate deficiency from poor diet or diuretics, or excess linked to kidney dysfunction. Doctors use this test to evaluate metabolic health and guide electrolyte management.

The Folate RBC Test measures folate levels inside red blood cells, providing a more accurate reflection of long-term folate status than serum tests. Folate is essential for DNA synthesis, red blood cell production, and nervous system health. Low levels may indicate poor diet, malabsorption, or anemia. Doctors order this test for patients with fatigue, weakness, or neurological issues. Results help diagnose folate deficiency and guide nutritional treatment.

The Copper RBC Test measures copper levels inside red blood cells, reflecting long-term copper status and cellular availability. Unlike serum copper, which can fluctuate, RBC copper gives a more accurate picture of tissue stores. Abnormal results may indicate copper deficiency, malnutrition, malabsorption, Wilson’s disease, or excess copper exposure. Doctors use this test to evaluate metabolic health, monitor treatment, and support diagnosis of mineral imbalances.

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 Manganese RBC Test measures manganese levels within red blood cells to assess long-term status of this essential trace element. Manganese plays a role in enzyme activation, bone development, and nervous system function. Abnormal levels may indicate nutritional deficiency, impaired absorption, or toxicity from environmental or occupational exposure. This test supports evaluation of metabolic health and trace mineral balance.

The Cholinesterase Serum Plasma RBC Test measures cholinesterase activity in blood to assess liver function, inherited enzyme deficiencies, or exposure to toxic chemicals such as pesticides. Low activity may indicate liver disease, malnutrition, or poisoning from organophosphates. Doctors use this test to monitor patients at occupational risk, evaluate unexplained symptoms, and support diagnosis of liver or neuromuscular disorders.

The CBC with H/H, RBC, Indices, WBC and Platelets Test evaluates overall blood health by measuring hemoglobin, hematocrit, red blood cell count, size and indices, white blood cell levels, and platelets. It helps detect anemia, infections, clotting disorders, and immune or bone marrow conditions. Frequently ordered in routine exams, this test supports diagnosis, monitoring of chronic disease, and assessment of general health.

The Chromium RBC Test measures chromium levels in red blood cells to evaluate long-term chromium status. Chromium is an essential trace element involved in glucose metabolism, insulin sensitivity, and lipid regulation. Abnormal RBC chromium levels may indicate dietary deficiency, supplementation effects, or toxic exposure. This test supports assessment of metabolic balance, nutritional health, and heavy metal monitoring.

The Lithium RBC Test measures lithium levels inside red blood cells, offering a more stable reflection of long-term exposure compared to serum testing. Lithium is used in the treatment of bipolar disorder and other mood conditions, and monitoring intracellular levels helps evaluate therapeutic effectiveness, detect toxicity, and guide dose adjustments. This test provides insight into psychiatric care, drug monitoring, and patient safety.

The Antibody Screen RBC with Reflex to Identification detects unexpected antibodies in red blood cells that may cause transfusion reactions or pregnancy complications. If antibodies are found, reflex testing identifies their specificity. Doctors use this test to ensure safe blood transfusions, evaluate prenatal risks of hemolytic disease of the newborn, and guide compatibility testing, helping protect patients during transfusion and pregnancy care.
