Reverse T3 Test

What the Reverse T3 Test looks at

The Reverse T3 (rT3) blood test is used to help determine if an individual has "nonthyroidal illness syndrome" or "sick euthyroid syndrome" as opposed to.

Sample type and collection

This panel is analyzed from a blood sample. The sample is collected at an accredited partner collection site, and you choose the location and appointment time during checkout. A trained collection specialist handles the sample, so no clinic visit or physician referral is required for the order itself.

Preparation

Routine preparation only. Confirm any fasting or timing instructions with the collection site when you book.

Turnaround and reporting

A typical turnaround is 1-3 business days. Results are released to you through the performing laboratory's own secure portal, so there is a single source for the numbers. Treat any timing estimate as a guide rather than a guarantee, since lab workloads fluctuate.

Cost and how to compare options

When you compare Reverse T3 Test prices, three details matter more than the headline number: whether the collection fee is included, how quickly the performing lab releases results, and how far you would travel to a participating site. Bundled panels are usually cheaper than ordering each marker on its own. The amount shown at checkout is the amount that applies.
