Thyroid Profile (T3, T4 & TSH), in Navi Mumbai

Fasting and dietary instructions:

No fasting is required for this test. However, as a general precaution, avoid alcohol and a heavy, fatty meal the evening before any blood test. These can temporarily alter several commonly tested markers even in tests that do not require strict fasting.

Medication guidance:

If you are on levothyroxine (thyroid hormone replacement), do not take your morning dose before the blood draw , have the sample collected first, then take your medication. This gives the most accurate reading of your baseline thyroid hormone level before the daily dose is absorbed into the system.

What to bring:

Bring your prescription, a government-issued ID, and your OPD insurance details. Inform the phlebotomist of any recent illness, active infections, allergy to latex, or history of fainting during blood draws , so appropriate care can be taken during the procedure.

Timing:

Morning appointments are recommended for most blood tests. Biological markers tend to be most stable before meals and physical activity, giving the most consistent, comparable results. Booking an early slot also means you can eat and resume normal activity sooner after the test.

When does a doctor order Thyroid Profile (T3, T4 & TSH)?

Endocrinologists order Thyroid Profile (T3, T4 & TSH) routinely for all patients receiving thyroid medication, for pregnant women (thyroid dysfunction affects foetal development), for individuals with a family history of thyroid disease who have never been screened, and for post-thyroidectomy patients who need lifelong hormone monitoring.

Who should get Thyroid Profile (T3, T4 & TSH) done?

Thyroid Profile (T3, T4 & TSH) is a common panel that checks how the thyroid gland is working. Doctors order it for symptoms such as fatigue, unexplained weight change, cold or heat intolerance, hair loss, or irregular heartbeat. Thyroid testing is especially important during pregnancy. Untreated maternal hypothyroidism is associated with impaired foetal neurodevelopment, miscarriage risk, and pregnancy complications. Women planning a pregnancy or in the first trimester should have thyroid levels checked proactively even if they feel well. Post-thyroidectomy patients require lifelong thyroid hormone monitoring.
