Mercury, Blood
Tracks mercury exposure, most often from fish, and the form that affects the nervous system.
Consider this test if:
- You eat large predatory fish (tuna, swordfish, shark, mackerel) frequently
- Planning pregnancy or pregnant and following fish-consumption advisories
- Occupational or hobby exposure to mercury (smelting, dental work, manufacturing)
- Investigating tremor, coordination or speech changes, numbness, or visual-field changes
- Wanting a baseline before changing your diet or after high fish intake
- 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 required. For occupational exposure monitoring, the recommended draw is at the end of the shift at the end of the work week. Otherwise timing is flexible, though levels reflect recent exposure, so a recent large fish meal can raise the result.

What this test is for
Whole blood mercury measures recent and ongoing exposure to mercury, the heavy metal most people encounter through eating fish and shellfish. Blood is the preferred sample for organic mercury (methylmercury), which concentrates in red blood cells and predominantly affects the central nervous system; symptoms of significant exposure include tremor, impaired coordination and speech, constricted visual fields, numbness, and irritability. High consumption of large predatory fish (tuna, swordfish, shark, king mackerel) is the most common nonindustrial source, and CDC data found roughly 6% of childbearing-age women at or above the reference level, which is why pregnancy planning is a common reason to check it.
This whole blood test is the right choice for suspected organic mercury (methylmercury) exposure. Inorganic and metallic mercury exposure, which is mostly occupational and affects the kidneys and lungs, is tracked better with a urine mercury test, and the separate serum and red-blood-cell mercury forms are used for specific clinical questions.

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. It is never a profit on the test itself. Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9 per month, and any applicable lab order or draw fee is itemized before you pay.
Where do I get tested?
Choose an available partner lab at checkout. If your cart contains multiple blood tests, Mito helps consolidate the eligible tests at one lab when possible. At-home kits and scans follow the collection or appointment process shown on their product page.
Is this eligible for HSA/FSA?
Yes. Eligible tests can be paid for with an HSA or FSA card at checkout.
When will I get my results?
Your results appear in your Mito dashboard after the laboratory completes processing. A clinician then reviews them before your analysis and personalized action plan are finalized. Timing varies by test, and specialty assays and at-home kits may take longer.
Do I need a physician's order?
No. Mito provides the laboratory order when one is required, so you do not need to arrange a separate physician visit before purchasing.
