Order Zinc Blood Test from JustLabs for $20. Price includes lab processing at Quest Diagnostics. A one-time $18 collection fee applies per order. No insurance required.
Zinc is an essential trace mineral involved in over 300 enzymatic reactions, including immune function, wound healing, thyroid hormone production, and testosterone synthesis.
Zinc is the second most abundant trace mineral in your body and is vital for countless biological processes. It plays crucial roles in immune function, wound healing, protein synthesis, DNA synthesis, cell division, and the proper functioning of taste and smell. Zinc is also essential for thyroid hormone production and testosterone synthesis.
Your body doesn't store zinc, so you need regular dietary intake from foods like meat, shellfish, legumes, nuts, and seeds. Zinc deficiency is surprisingly common globally and can occur due to inadequate dietary intake, malabsorption, chronic diseases, or increased requirements (pregnancy, growth, illness).
Because zinc competes with copper for absorption, high-dose zinc supplementation can cause copper deficiency. Testing both minerals together provides a more complete picture of your mineral status.

What's Measured
What This Test Measures
This test measures the concentration of zinc in your blood serum. Normal levels typically range from 60-120 mcg/dL. Levels below 60 mcg/dL suggest deficiency, while very high levels may indicate excessive supplementation.
Who Should Consider This Test
People with frequent infections or slow wound healing, vegetarians and vegans (zinc from plant sources is less bioavailable), individuals with digestive disorders, those with hair loss or skin problems, men with low testosterone symptoms, pregnant or breastfeeding women, and anyone taking high-dose zinc supplements (to monitor levels).

When to Get Tested
No fasting required, though fasting may provide more consistent results. Avoid zinc supplements for 24 hours before testing. Time of day can affect levels (higher in morning).
Understanding Your Results
Normal serum zinc is typically 60-120 mcg/dL. Low levels indicate deficiency requiring dietary changes or supplementation. Interpretation should consider symptoms, as serum zinc may not fully reflect tissue stores. Very high levels (>150 mcg/dL) suggest excessive supplementation and risk of copper depletion.
What to Expect
After placing your order, you'll receive an email from Rupa Health (our lab order partner) within 24 business hours to sign a consent form and schedule your blood draw at a Quest Diagnostics location.
The blood draw typically takes just a few minutes. Results are usually available within 2-3 business days and will appear in your secure Justlabs dashboard.
Our results include reference ranges and easy-to-understand indicators showing whether your values are within normal limits.
