Which thyroid test is the most accurate?

Assessment of TSH is the single most useful test of thyroid function in the vast majority of patients. Primary care providers should seldom need to order any other biochemical thyroid test. In most cases the TSH will be within the normal range, and no further testing is indicated.

What is the most sensitive thyroid function screening test?

The blood test for TSH, which is the most sensitive marker of your thyroid status, is used as a biochemical marker to ensure that your thyroid hormone replacement is adequate. It is recommended that patients on thyroid hormone replacement should keep their TSH within the reference range.

Is TSH sufficient for thyroid test?

Research finds that a simple TSH test is enough to identify hypothyroidism in 99.6% of the tests performed. You may have heard of expanded or full thyroid panels, which often include tests for TSH, total T3, total T4, free T3, free T4, anti-TPO antibodies, thyroglobulin, and reverse T3.

Is TSH or T4 more important?

T4 is produced in large quantities by the thyroid. However, TSH is a far superior screening test because small changes in T4 cause large TSH spikes.

What is the best time for thyroid test?

I recommend getting your thyroid function tests done first thing in the morning, bringing your medications with you, and taking them right after you have your thyroid function tests to ensure that you get accurate test results.

How do you test for thyroid antibodies?

An antibody test can help your doctor figure out if your immune system is attacking the thyroid gland, or if something else might be the cause. Your doctor or a lab technician will take a sample of your blood to measure how many antithyroid antibodies are in it. Some medicines can affect test results.
