Procedure Master Number

LAB10885

Procedure ID

114270

Clinical Info

Accurate measurement of serum thyroglobulin (Tg) in patients with known or suspected antithyroglobulin autoantibodies (TgAb) or heterophile antibodies (HAb)

Reflex testing of samples with previously unknown TgAb status that prove TgAb positive during immunoassay testing

Assisting in the differential diagnosis of early phase silent thyroiditis versus Graves' disease in patients without thyroid cancer (the mass spectrometry-based method would only be required if these patients have TgAb or HAb)
