Thyroid Antibodies
Test for Thyroid Peroxidase (TPO) and Thyroglobulin Antibodies (TGA)
|
Hashimoto’s hypothyroidism is affecting people of all ages at an alarming rate. As antibodies attack the thyroid gland over time, you may develop low thyroid symptoms such as weight gain, fatigue, hair loss, constipation, slow metabolism, swelling, increased sensitivity to cold, and depression. Symptom fluctuations, a medicine cabinet full of medications/supplements, and doctors unable to give a correct diagnose are some of the signs that you may have an autoimmune condition. Even though Hashimoto’s disease constitutes over 80% of all hypothyroid cases, it is often missed. Many times traditional laboratory tests such as Thyroid Simulating Hormone (TSH), T4, and T3 will be within normal ranges in cases of Hashimoto’s. |

Run this test run if you suspect Hashimoto’s or you have been previously diagnosed with hypothyroidism and these tests were not ordered. Two sets of antibodies (Thyroid Peroxidase (TPO) and Thyroglobulin (TGB) antibodies) are used to diagnose Hashimoto’s. Since these antibodies fluctuate over time, one should consider TH1/TH2 and CD4/CD8 ratio tests to monitor their treatment plan. These tests give detailed information about the health of your immune system.
What’s Being Tested:
- Anti-thyroglobulin antibodies (TGA)
- Anti-thyroid peroxidase antibodies (TPO)
Notes:
-
Since auto-antibodies tend to flutuate, it is important to retest once (1) per week for three (3) weeks if results are initially negative.
Fasting: No
Specimen: Blood (Draw Location | How It Works | FAQs)
