T3 Reverse Test at Home in Dubai
Also known as: RT3, REVERSE T3
Included
About the Test
Reverse T3 is an inactive form of the T3 hormone that the body produces when it converts thyroxine. Measuring it helps clarify unusual thyroid pictures, especially when someone feels hypothyroid but standard tests look normal, or during serious illness, stress and starvation when the body shifts hormone conversion away from active T3. It is a specialist add-on rather than a routine screen, usually ordered alongside TSH, Free T4 and Free T3 for a fuller interpretation.
What is it? Reverse T3 (RT3) measures the metabolically inactive mirror-image of triiodothyronine produced during thyroxine conversion.

T3 Reverse test: purpose, preparation and results
Why take the T3 Reverse test?
- Investigate persistent fatigue or hypothyroid-type symptoms when TSH and Free T4 appear normal
- Assess thyroid hormone conversion during severe illness, injury, prolonged stress or fasting
- Add depth to a thyroid work-up when active and inactive hormone balance is in question
How to prepare for the T3 Reverse test
No fasting is required for Reverse T3. Tell the nurse about any thyroid medication, biotin supplements, steroids or recent serious illness, as these can affect the result and how your doctor reads it.
Understanding your T3 Reverse results
A raised Reverse T3, particularly relative to Free T3, can point to the body slowing thyroid activity during illness or stress, while results are best read together with TSH and Free T4. Because this is a nuanced marker, always review it with a doctor rather than in isolation.

Frequently Asked Questions
Anything else? Ask on WhatsApp — we usually reply in three minutes.
Reverse T3 is a specialised send-out assay, so results take 15 to 20 days. Your doctor-reviewed report is delivered to you on WhatsApp and email once the partner lab has completed and validated the analysis.
No fasting is needed for Reverse T3. You can eat and drink normally. If you also book a lipid or glucose panel that does require fasting, follow the fasting instruction for that panel instead.
It is usually added when you have hypothyroid-type symptoms but ordinary thyroid tests look normal, or when serious illness or stress may be altering how your body converts thyroid hormone. It is not a first-line screening test.
Yes. Thyroid medication, steroids and high-dose biotin can influence thyroid readings. Mention everything you take to the nurse so your doctor can interpret the result accurately. Do not stop any medication without medical advice.
