Thyroid Profile Test - T3, T4 & TSH in Chandigarh

A thyroid test checks how well your thyroid gland is working by measuring hormones in your blood. TSH stands for Thyroid Stimulating Hormone — the main value doctors check first, since it's the most sensitive indicator of thyroid function.

A standard thyroid profile includes TSH, Total T3, and Total T4. An advanced profile can add Free T3, Free T4, and Anti-TPO Antibody for autoimmune thyroid conditions.

TSH is typically 0.4–4.5 mIU/L, Total T3 is around 80–200 ng/dL, and Total T4 is around 5.0–12.0 µg/dL, though ranges vary slightly by lab, age, and sex — always check the range printed on your own report.

No, fasting is not required. You can eat and drink normally before the test and have it done at any time of day.

Since fasting isn't required, a thyroid test can be done any time. Morning samples are sometimes preferred for consistency between repeat tests, but it isn't medically required.

Common signs include fatigue, unexplained weight gain or loss, hair thinning, cold or heat intolerance, irregular periods, mood changes, dry skin, a noticeably fast or slow heartbeat, muscle weakness, and constipation or diarrhea. Having one or two of these doesn't confirm a thyroid issue — a blood test is what actually tells you.

Thyroid tests don't usually come back 'positive' or 'negative' the way an infection test does — they report numeric hormone levels that are then compared against a reference range. An 'abnormal' result just means a value falls outside that range and needs your doctor's interpretation.

TSH is considered the most important screening value because it's the most sensitive and usually the first to shift when thyroid function changes. T3 and T4 are checked alongside it to understand the full picture.

There's no single universal cutoff, but a TSH well above 10 mIU/L is generally considered significant and is usually a reason for your doctor to start or adjust treatment. Any high reading should be reviewed with a doctor rather than compared to online numbers alone.

Yes, you can book a thyroid test directly for preventive screening. However, interpreting the results and deciding on any treatment should involve a doctor.

There's no fixed expiry, but thyroid hormone levels can shift over weeks to months, so doctors often ask for a fresh test every few months when monitoring a condition or medication dose.
