The cobalt blood test measures the amount of cobalt in your blood. It is usually ordered to check for exposure to cobalt, which can come from metal implants, certain industrial jobs, or vitamin supplements. It may also be used to monitor people with artificial joints that contain cobalt-chromium alloys.

What it measures

  • Cobalt, blood — The main measurement. It shows how much cobalt is in your blood at the time of the test.
  • Cobalt, serum or plasma — Sometimes the test is done on the liquid part of blood rather than whole blood. The lab will specify which one.
  • Creatinine — A waste product that shows how well your kidneys are working. It may be checked along with cobalt because the kidneys help remove cobalt from the body.
  • Hemoglobin — The part of red blood cells that carries oxygen. Cobalt can affect red blood cell production, so this may be checked too.

Who it is for

A doctor may order this test if you have a metal hip or knee implant and symptoms like pain, swelling, or nerve problems. It can also be ordered if you work with cobalt or have been exposed to it in another way.

Preparation

No special preparation is usually needed. You do not have to fast. Tell your doctor about any vitamins or supplements you take, especially those containing vitamin B12, because they can contain cobalt.

Results and what they mean

Results are reported as a number, often in micrograms per liter (mcg/L). Your doctor will compare your result to a reference range and consider your symptoms, medical history, and other tests. This information is general and not medical advice; only a qualified clinician can interpret your results.
