Comprehensive blood test to measure vitamin B6 and calcium levels in corticosteroid users.
This test measures vitamin B6 (pyridoxine) and calcium levels in your blood. Corticosteroids can interfere with nutrient absorption, making deficiency testing crucial. Identifying deficiencies helps you and your doctor determine if supplementation is needed to improve health and address potential symptoms related to these nutrient shortfalls. The test provides valuable insights into your nutritional status, particularly if you're taking corticosteroids.

Who Is This For?
Vegetarians and vegans (at higher risk of B12, iron, and zinc deficiency). Older adults, as nutrient absorption decreases with age. Anyone on restrictive diets or with digestive conditions affecting absorption. People experiencing unexplained fatigue, brain fog, poor wound healing, or hair loss. Athletes with high nutrient demands from training.
What's Included
Preparation Required
Fasting for 8–10 hours is recommended for some nutrient tests but not all — check with your provider. Continue taking your regular supplements unless told otherwise (the test measures your steady-state levels). Morning draws are preferred for consistent results.
Biomarkers Tested
4Vitamin B6 (Pyridoxine) is important for protein metabolism, cognitive development, and immune function. Deficiency can lead to anemia and neurological issues.
The most abundant mineral in the body, essential for bone health, muscle contraction, nerve function, and blood clotting. Blood calcium is tightly regulated by parathyroid hormone and vitamin D. Abnormal levels can indicate parathyroid disorders.
Essential for nerve function, DNA synthesis, and red blood cell formation. B12 deficiency can cause anemia, neuropathy, fatigue, and cognitive impairment. Common in vegans, vegetarians, older adults, and those taking metformin or acid-reducing medications.
Essential for DNA synthesis, cell division, and red blood cell formation. Folate deficiency causes megaloblastic anemia and, during pregnancy, increases the risk of neural tube defects. Works closely with vitamin B12.
