Doctor/Practitioner
Certain lab tests may come back in the "normal" range. Reference ranges do not always mean "optimal." Patients may still experience symptoms in the "normal" range. It is important to speak with a qualified health practitioner regarding normal vs optimal.
Note
These lab tests can be purchased without a physician and drawn at a Quest Diagnostics location. A small draw fee of $ 8 will be applied at checkout. There are no other "hidden" fees unless noted on the lab test.
Currently, NY, NJ, and RI state laws prohibit direct-access testing. These lab tests cannot be conducted at lab locations within these states at this time.

Assists in the diagnosis of thyroid diseases such as endemic goiter, Graves Disease, autoimmune thyroiditis, Addison's Disease, insulin-dependent diabetes mellitus, Hashimoto's Disease and polyendocrine auto-immunopathies.

TPO Ab can reach very high levels (10,000 or greater), however, our assay is only validated up to 900, so although the analyzer will report a value above 900, the accuracy was not determined (or values became non-linear above 900) so any value greater than 900 is reports as “>900.” If tracking requires values above 900 for the Thyroid Peroxidase Antibodies, then order test TPO Antibody Endpoint
