What this laboratory test evaluates
Micronutrient, Cobalt, Blood
Cobalt is a dietary mineral. Most of the cobalt we absorb is passed out through urine, with a small amount leaving through stool. While cobalt is essential, too much can be harmful, especially in certain work environments. Since cobalt isn't mined in the U.S., it's brought in from other countries.
What patients is this test right for?This test might be recommended for individuals exposed to high levels of cobalt, especially in industrial settings, or to assess dietary cobalt levels.
What type of sample is required for this test?4 mL whole blood.
It needs to be collected in an EDTA trace metal-free (royal blue-top) tube.
