Preparation
Anti TPO (Anti Microsomal/Thyroperoxidase Antibody) detects antibodies against thyroid peroxidase, the enzyme your thyroid uses to make hormones. It is the marker of autoimmune thyroid disease — the condition behind most thyroid problems in Kerala, especially in women.
A positive Anti TPO changes the story of an abnormal TSH. It explains why hypothyroidism appeared, predicts that medication doses may drift over time, and flags the need for periodic monitoring even when current levels look normal. It is also relevant in pregnancy, where untreated autoimmune thyroid disease affects both mother and baby.
The test needs no fasting and no clinic visit — a home blood draw at your slot, processed at an NABL-grade partner lab, with the report in your app ready for your physician or endocrinologist.
Many doctors order it when TSH is borderline high-normal or when there is a goitre, family history of thyroid disease, or fertility concerns. Positive antibodies predict future hypothyroidism even before TSH shifts.
