Early detection and treatment are crucial as these infections can have severe long-term health effects if untreated.
The vitamin A (retinol) test analyzes vitamin A levels in the blood, a vital nutrient for vision, immune system health, and cell functions. It is conducted to detect and monitor vitamin A deficiency symptoms like night blindness and dry skin, as well as assess treatment effectiveness. The test involves obtaining a blood sample from a vein, which is examined in a laboratory for results reported in micrograms or micromoles per liter. Optimal vitamin A levels range from 20-80 mcg/dL or 0.7-3.0 umol/L, with values below or above indicating deficiency or toxicity risks, respectively.
A Vitamin B1 test measures the levels of Vitamin B1 in the blood. Vitamin B1 is crucial for converting food into energy and maintaining a healthy nervous system. The test may be ordered if a deficiency is suspected, which can cause symptoms like fatigue and muscle weakness. Deficiency can result from inadequate intake, alcohol use, or medical conditions affecting absorption. The test involves a blood draw and can help determine if supplementation or dietary changes are necessary.
A vitamin B12 and folic acid test, which measures the levels of these nutrients in the body. Vitamin B12 and folic acid are crucial for nervous system function, red blood cell production, and DNA synthesis. Low levels can lead to megaloblastic anemia, while high levels may indicate health issues like liver disease or leukemia. Doctors order this test for patients with symptoms of deficiency, family history of deficiencies, or certain medical conditions affecting absorption. Patients may need to fast before the test, and results help determine if vitamin supplementation is needed.

Doctors order this test for patients with symptoms of deficiency, family history of deficiencies, or certain medical conditions affecting absorption. Patients may need to fast before the test, and results help determine if vitamin supplementation is needed.
A Vitamin B12 test is conducted to measure Vitamin B12 levels, which are essential for maintaining nerve cells, DNA production, and red blood cell formation. Low levels may cause fatigue, weakness, and nerve damage. The test is ordered for those with symptoms of deficiency or related risk factors. Results are reported in picograms per milliliter or picomoles per liter, with normal levels ranging from 180-914 pg/mL or 133-675 pmol/L.
A vitamin B12 test measures the levels of the essential vitamin in the blood. Vitamin B12, crucial for brain function and red blood cell formation, is typically tested for deficiencies causing symptoms like fatigue, numbness, and memory issues. The test involves a blood draw and lab analysis, with normal levels falling between 200-900 pg/mL. Abnormal results may suggest a deficiency or underlying medical conditions.
The Vitamin B2 (Riboflavin) test measures riboflavin levels, an essential vitamin for health including energy production, metabolism, and skin/eye health. Low levels can lead to symptoms like fatigue and mouth inflammation, while high levels are rare. The test involves a blood sample and fasting may be required. Results determine if riboflavin levels are normal. Dietary changes or supplements may be recommended if levels are low.
The vitamin B3 (niacin) test measures niacin levels in the blood to detect deficiencies or excess. Niacin is vital for nervous system, digestion, and skin health. Symptoms like rash, diarrhea, memory loss, or fatigue may trigger this test, especially for those at risk due to health conditions or medications. Blood analysis determines niacin levels and guides potential dietary changes or supplementation to address any deficiencies or excesses.
The Vitamin B5 test measures levels of this essential nutrient in the body, crucial for energy metabolism and skin health. It is ordered if a deficiency is suspected, and results guide treatment through dietary changes or supplements. Consult a healthcare provider before starting any new regimen.
The Vitamin B6 test measures the level of this essential vitamin in the blood to assess the nervous system's functioning and metabolism. It can be ordered if there are signs of deficiency or excess, which may cause fatigue, nerve damage, and other issues. Results aid in diagnosing conditions like anemia and metabolic disorders, guiding treatment decisions. Pre-test fasting may be required, with blood drawn from a vein for analysis.
Vitamin C testing measures the levels of this essential nutrient in the blood. Vitamin C plays a crucial role in maintaining immune system health and can lead to issues like scurvy if deficient. On the other hand, excessive intake can have adverse effects. It is recommended to consult with a healthcare provider before taking supplements to ensure proper intake.
The Vitamin D 25-Dihydroxy (Calcitriol) test measures calcitriol levels in the blood, which is crucial for bone health, immune function, and calcium regulation. Abnormal levels can indicate Vitamin D issues like osteoporosis. Doctors order the test for symptoms like bone pain and prescribe treatment like Vitamin D supplements.
The vitamin D 25-hydroxy blood test measures your vitamin D levels, crucial for bone health, immune function, and cell growth. Low levels can lead to osteoporosis and weakened immunity, while high levels can cause toxicity. The test is ordered if there are concerns about deficiency or toxicity, performed during check-ups or when experiencing bone pain or fatigue. It measures 25-hydroxy vitamin D levels in blood, reported in ng/mL or nmol/L.
The vitamin E test measures levels in the blood, an antioxidant crucial for cell protection. Deficiency may cause weakness and nerve issues, while excess can lead to diarrhea and bleeding. A blood sample is taken to assess vitamin E levels and consult a healthcare provider for concerns.
