Non-Malaysian citizens are subject to 6% SST, to be verified and paid at the counter before screening.

Free T4 (FT4) Test

Introduction

Free T4 (FT4, Free Thyroxine) is one of the main hormones secreted by the thyroid gland. A small portion circulates in its free, unbound form, which enters cells directly to regulate metabolism, energy use, and body temperature. Unlike total T4, FT4 more accurately reflects thyroid function.

Why Take an FT4 Test?

  • Diagnosis of thyroid disorders: Elevated FT4 suggests hyperthyroidism, while low FT4 indicates hypothyroidism.
  • Treatment monitoring: Tracks the effectiveness of thyroid therapies.
  • Comprehensive evaluation: Often tested alongside FT3 and TSH for a complete thyroid profile.

Method & Workflow

A venous blood sample is collected to measure serum FT4 levels. Doctors interpret the results together with FT3, TSH, and clinical symptoms.

Who Should Consider Testing?

  • Individuals with symptoms like palpitations, weight changes, heat or cold intolerance
  • Patients receiving thyroid function treatment
  • Those with a family history of thyroid disease
  • Anyone seeking endocrine screening as part of a full health check

Frequently Asked Questions (FAQ)

Q1: What is the difference between FT4 and FT3?
A: FT4 is the main thyroid hormone at higher concentration, while FT3 is more active and largely converted from FT4.

Q2: What does high or low FT4 mean?
A: High FT4 usually indicates hyperthyroidism, while low FT4 suggests hypothyroidism or reduced thyroid function.

Q3: Why combine FT4 with TSH testing?
A: FT4 reflects thyroid hormone secretion, while TSH shows pituitary regulation. Together they provide a clearer diagnosis.
