The thyroid blood test (peroxidase antibodies) detects an enzyme released from the thyroid. The enzyme plays a significant role in the conversion of T4, one thyroid hormone, to T3, which is essential for metabolism. Detecting thyroid peroxidase antibodies may suggest that the immune system is attacking the thyroid.

Why Should You Test for Peroxidase Antibodies?

• Examine symptoms that may suggest a thyroid disorder.
• Gain a comprehensive understanding of thyroid health and function.
• Track thyroid activity and changes over time.

Preparing for Thyroid Blood Test Appointment

• Stay hydrated by taking plenty of water 24 hours before your appointment. This helps make the blood removal process easier.
• Dress in loose-fitting clothes that make accessing your arms and hands easy.
• If you are taking anticoagulants, waiting until after your test is advisable. If this seems impossible, you may take them beforehand, but only if necessary.
