Zinc
A trace mineral central to immunity, wound healing, taste, and skin health.
Consider this test if:
- Frequent infections, slow-healing wounds, hair loss, or unexplained skin rashes
- Loss of taste or appetite, or a restrictive, vegetarian, or vegan diet
- Malabsorption, chronic diarrhea, or long-term parenteral nutrition
- Following oral zinc therapy, including in Wilson's disease
- Checking whether a zinc supplement is moving your level or risks suppressing copper
- HSA/FSA eligible
- Typical results in 2-4 days · Reviewed by a real clinician
- Drawn at a CLIA/CAP-accredited lab near you ·
Pre-test considerations
No fasting is generally required. Zinc supplements raise the result, so note your dose and timing, and keep your routine consistent if you are tracking change. Collection uses a metal-free tube to avoid contamination, since ordinary tubes and gel-barrier tubes can falsely alter the reading.

What members say on Trustpilot
What this test is for
Zinc is an essential trace mineral involved in immune function, wound healing, protein synthesis, taste and smell, skin integrity, and normal growth. Low zinc is linked to frequent infections, slow-healing wounds, hair loss, rashes, loss of taste or appetite, and impaired growth in children, and is more likely with malabsorption, heavy GI losses, restrictive diets, or long-term parenteral nutrition. High zinc usually reflects supplementation or occupational exposure, and excess zinc can suppress copper. This serum or plasma test measures circulating zinc, the standard way to assess current status, evaluate suspected deficiency, and follow zinc therapy, including oral zinc in Wilson's disease.
It differs from the related catalog variants by what each measures: Zinc, RBC and Zinc, Whole Blood capture intracellular and total blood content, Zinc Protoporphyrin reflects iron-deficient red-cell production, and the ZnT8 antibody is an autoimmune diabetes marker rather than a nutritional one.

Frequently asked questions
View all FAQsHow does pricing work?
Every test shows the member price next to the standard non-member price, so you can see what membership saves you. The member price is our cost — covering the lab and what it takes to run the service — never a profit on the test itself; Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9/mo, and you still pay the lab’s order fee. Prices are itemized before you pay, with no hidden fees.
Where do I get tested?
Choose a partner lab (Quest, Labcorp, or BioReference) at checkout. If your cart spans multiple tests, we consolidate the whole order onto a single lab so you only make one visit.
Is this eligible for HSA/FSA?
Yes. This test is HSA/FSA eligible, and you can pay with your HSA/FSA card at checkout.
When will I get my results?
Your results post to your dashboard once your lab completes them, then a clinician reviews them and your full analysis and personalized action plan (with clear next steps) follow. Turnaround varies by test: specialty assays and at-home kits take longer, and each test shows its expected turnaround before you buy.
Do I need a doctor’s order?
No. Mito provides the lab order for you, so you can book and get tested without a separate doctor visit.
