The Thyroid Peroxidase Antibodies test (TPO Antibodies test) also known as the Antithyroid Microsomal Antibodies test may be used to help diagnose hypothyroidism and thyroiditis. The TPO Antibodies test may also be used to help diagnose and monitor autoimmune thyroid diseases such as Grave's Disease and Hashimoto's Thyroiditis. The TPO Antibodies test may also be useful in determining if a pregnant woman is at risk for passing thyroid disease onto her child. Turnaround time for the TPO Antibodies test is typically 1-3 business days.
This thyroid test has no fasting requirements.
