Thyroid tests are simple, accurate, and done with a regular blood draw. Understanding results helps you monitor your condition.
Basic Tests:
- TSH (Most Important): Pituitary hormone.
Normal: 0.4-4.0 mIU/L.
High = hypothyroidism (pituitary screaming: "Work more!").
Low = hyperthyroidism. - Free T4: Main hormone.
Normal: 0.8-1.8 ng/dL.
Low with high TSH = confirmed hypothyroidism. - Free T3: Active hormone.
Normal: 2.3-4.2 pg/mL.
High = hyperthyroidism.
Additional Tests as Needed:
- Anti-TPO: Antibodies — if elevated = Hashimoto's disease (autoimmune cause of hypothyroidism).
- Anti-TSI or TRAb: Antibodies — if elevated = Graves' disease.
- Thyroglobulin: For thyroid cancer monitoring after treatment.
When to Test:
- Symptoms of hypo- or hyperthyroidism.
- Family history of thyroid disease.
- Women planning pregnancy.
- As part of routine comprehensive checkup.
