Check and manage the level of cobalt and chromium metals post surgery.
Vitamin and nutrient testing measures the levels of essential micronutrients in your blood — vitamins, minerals, and trace elements that your body needs in small amounts but cannot function without. Common tests include B12 (critical for nerve function and red blood cell production), folate (essential for DNA synthesis and especially important in pregnancy), zinc (immune function, wound healing), magnesium (involved in 300+ enzymatic reactions), and selenium (thyroid function, antioxidant defense). Deficiencies are more common than most people realize, particularly in B12 (affecting up to 20% of older adults), vitamin D, iron, and magnesium. Symptoms are often vague — fatigue, brain fog, poor sleep — making testing the only reliable way to identify specific gaps.
Key Details
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
4An essential trace mineral in its trivalent form (Cr³⁺), important for insulin signalling and glucose metabolism. Hexavalent chromium (Cr⁶⁺) from industrial exposure is carcinogenic. Testing measures total chromium levels.
A liver enzyme that helps convert proteins into energy. ALT is found primarily in the liver, making it a highly specific marker for liver damage. Elevated levels may indicate hepatitis, fatty liver disease, or medication-related liver injury.
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.
