What happens if my thyroid function test shows borderline results?

If your thyroid function test (TFT) shows borderline results, such as slightly elevated TSH or slightly low T4, your doctor may recommend a wait-and-see approach with follow-up testing in a few months. Borderline results may indicate early-stage hypothyroidism or hyperthyroidism, but symptoms may not yet be present or significant. Your healthcare provider may also check for other factors, such as thyroid antibodies, to assess whether an autoimmune condition is affecting your thyroid. Lifestyle changes, medication adjustments, or closer monitoring may be recommended depending on your overall health and symptoms.
