With the Honest Explanation

Reference ranges vary between laboratories. This is not a quality issue — it is because each lab calibrates its instruments and methods using different populations, reagents, and equipment. A result of 5.5 at one lab may show as slightly different at another. What matters is: (1) always using the same lab for serial monitoring, (2) understanding your trend over time, not just one reading. Gini's ranges are calibrated on our specific instruments and validated monthly against international reference samples. Read the full explanation →

Result Range Clinical Meaning
Normal3.5–7.8 pmol/LNormal active thyroid hormone
LowBelow 3.5 pmol/LReduced T3 — may explain symptoms despite normal TSH/T4
HighAbove 7.8 pmol/LOveractive thyroid or T3 toxicosis
Indian-Specific Context
Dr. Bhansali specifically tests Free T3 in patients who remain symptomatic despite normal TSH and T4 — this is where T3 deficiency is found.

What Your Result Means

If Your Result Is High

Overactive thyroid — T3 thyrotoxicosis. Can occur with normal T4.

If Your Result Is Low

Low T3 despite normal TSH is the reason 15–20% of hypothyroid patients feel unwell on T4-only treatment. They need combination T3+T4 therapy.

More Than a Lab — A Hospital Lab

Gini's Free T3 (Free Triiodothyronine) costs ₹150. Budget standalone labs charge less. The difference is not just equipment — it is what happens when your result is abnormal.

At a standalone lab, you get a report. At Gini, if your Free T3 is significantly abnormal, our team flags it to Dr. Anil Bhansali's office. You are not alone with a concerning number.

This is what a hospital lab means vs a standalone diagnostic centre. More on Gini's lab quality →
