Thyroid
TPO antibodies
Also written as Thyroid peroxidase antibodies.
Extended panel — run periodically
What it indicates
Antibodies directed at an enzyme the thyroid uses to make its hormones.
Why a series helps
Antibody levels can change across years, so occasional repeat measurement is what shows direction.
What this page does not tell you
What a particular TPO antibodies result means depends on you: your history, your medication, why the test was taken. Ziro does not interpret results for individuals and does not diagnose. If something in your results warrants a conversation, that conversation is with a doctor, and your results are downloadable so you can bring them.
