Cobalt lab testing measures the amount of cobalt in your blood. It is usually ordered when someone has a cobalt-containing medical implant, such as a metal-on-metal hip replacement, or when exposure to cobalt in the workplace is suspected. The test helps assess recent cobalt exposure.

What it measures

  • Cobalt (blood) — The amount of cobalt in your blood at the time of the draw.
  • Cobalt (serum or plasma) — Cobalt measured in the liquid part of blood; both serum and plasma are common.
  • Whole-blood cobalt — Cobalt measured in whole blood, which may better reflect longer-term exposure.

Who it is for

This test is typically ordered by an orthopedic surgeon, occupational medicine physician, or primary care clinician when a patient has a cobalt-containing implant or known workplace exposure.

Preparation

No fasting is required for cobalt blood testing. Tell your clinician about any cobalt-containing supplements, vitamins, or recent imaging contrast dyes, as these may affect results.

Results and what they mean

Results are reported as a number, usually in micrograms per liter (mcg/L), along with the laboratory's reference range. Your clinician interprets the result in the context of your symptoms, implant history, and other tests. This information is general and not medical advice; discuss your results with a qualified healthcare professional.

Requesting the Cobalt Lab Testing in California

Order online, choose a certified collection site in California, and review results through a secure portal. No referral is required, and orders are processed confidentially. With coastal metros, inland towns, and rural counties with very different access to testing, it pays to schedule your collection in advance.

Frequently asked questions

Do I need to fast before a cobalt blood test?

No, fasting is not required. You can eat and drink normally before the test.

How long does it take to get results?

Results are typically available within 1 to 3 business days.

Can my hip replacement affect my cobalt level?

Yes. Metal-on-metal implants can release cobalt, so your clinician may monitor levels over time.

Is this test covered by insurance?

Coverage depends on your insurance plan and the reason for testing. Check with your insurer or the lab before testing.
