Free T4 Price in Bangladesh

What is Free T4?

Free T4 (thyroxine) is an essential thyroid hormone that helps regulate metabolism, energy levels, and overall body function. A Free T4 test measures the unbound portion of thyroxine in the bloodstream, which is biologically active and available for use.

This test is commonly used to assess thyroid function, diagnose conditions like hypothyroidism or hyperthyroidism, and monitor thyroid-related treatments. Preparation for the test is minimal, although some medications may need adjustment.

Blood is drawn from a vein, with minor risks such as bruising. Abnormal Free T4 levels may indicate thyroid disorders, pituitary gland issues, or systemic illnesses, requiring further evaluation for accurate diagnosis and treatment.

What to expect & how to prepare

Free T4 is performed at a diagnostic centre or hospital lab. A trained technician collects the required sample (commonly a blood draw, urine sample, swab or an imaging scan, depending on the test) and sends it to the lab for analysis. Most routine tests take only a few minutes to sample, with reports typically ready the same day or within 24–48 hours.

• Fasting: some tests require 8–12 hours of fasting (water is usually allowed). Ask the centre when you book.
• Medication: tell the lab about any medicines or supplements you take, as some can affect results.
• Timing: certain hormone and biochemistry tests are best done in the morning — confirm the recommended time.
• Report: always have a registered doctor interpret your Free T4 result rather than self-diagnosing.
