FT3, FT4, TSH (ULTRASENSITIVE), in Prayagraj

Fasting and dietary instructions:

No special fasting is needed for this test. Avoid strenuous exercise, alcohol, and high-fat foods in the 12 hours before the test for the most consistent results. Stay well hydrated before the appointment.

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:

Carry your doctor's test order, a photo ID, and your corporate OPD insurance card to the appointment. If you have had this test done before, bring your previous reports , comparing values over time is clinically more meaningful than interpreting a single reading in isolation.

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 FT3, FT4, TSH (ULTRASENSITIVE)?

Endocrinologists order FT3, FT4, TSH (ULTRASENSITIVE) 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 FT3, FT4, TSH (ULTRASENSITIVE) done?

FT3, FT4, TSH (ULTRASENSITIVE) is part of a thyroid function panel used to check symptoms like fatigue, weight change, palpitations, temperature sensitivity, or mood shifts. Doctors order it to diagnose or monitor hypothyroidism, hyperthyroidism, thyroiditis, medication effects, and following thyroid surgery. Women above 30, particularly those with a family history of thyroid disease, irregular periods, PCOS, or plans to conceive, should consider annual thyroid screening. Men are less commonly affected but should be tested if they experience unexplained fatigue, weight changes, or low libido that cannot be attributed to other causes. Regular screening identifies subclinical thyroid disease before it progresses to overt dysfunction.
