What is Thyroxine Binding Globulin?

This test measures the amount of Thyroxine Binding Globulin (TBG) in your blood. TBG is a protein that carries thyroid hormones, primarily T4, throughout your bloodstream.

Why is this test important?

While TBG doesn't directly measure thyroid function, abnormal levels can affect total T3 and T4 measurements. It helps interpret total thyroid hormone results, especially when free hormone levels are normal but total levels are unusual.

How to Prepare

No special preparation required.

It depends on the test. Tests like lipid profile and fasting blood sugar require 10-12 hours of fasting. Tests like CBC, vitamin D, and thyroid do not require fasting. Each test page on our website clearly states the fasting requirements.
