Special instruction: Some tests in this bundle may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin (also termed as vitamin B7 or B8, vitamin H, or coenzyme R). It is recommended to stop biotin consumption at least 72 hours prior to the collection of a sample.
Preparation instructions: Samples should not be collected during or soon after the administration of heparin, an anti-coagulant as this may interfere with free T4 testing.
This bundle is curated to help attain detailed information on thyroid health in order to troubleshoot with their doctor, or for those who are just curious about how things are looking. It includes multiple markers that may help in getting a look at the big picture beyond just testing TSH or a thyroid panel alone.
Expected turnaround is within 4-6 days, although this may vary depending on other tests ordered for the same blood draw, and expected variation with testing.
