Comprehensive blood test to measure zinc levels and assess for deficiency or excess.
Zinc is an essential trace element crucial for immune response, wound healing, DNA synthesis, and cell division. This test evaluates zinc levels, vital for growth, development, enzyme function, and overall health. Zinc deficiency can cause hair loss, poor wound healing, weakened immunity, and skin problems. Conversely, zinc toxicity (rare but possible with excessive supplementation) can lead to nausea, vomiting, and stomach pain. This test helps diagnose and monitor zinc imbalances.
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
3An essential trace mineral involved in immune function, wound healing, DNA synthesis, and testosterone production. Zinc deficiency impairs immune response, delays wound healing, and can cause hair loss and taste changes.
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.
