DIO2
DIO2 (Type 2 Deiodinase) is a gene that encodes an enzyme essential for thyroid hormone regulation. It converts the inactive thyroid hormone thyroxine (T4) into its active form, triiodothyronine (T3), by removing an iodine atom. Expressed in tissues like the thyroid gland, brain, and brown adipose tissue, DIO2 helps mediate local, tissue-specific responses to thyroid hormones and supports metabolic and developmental processes.

The home test was straightforward with easy to follow instructions. The test result was detailed and clear in its presentation. Also had the opportunity to ask questions about the test result.

We looked at a lot of companies offering the same services but made the decision to go forward with get tested because the labs are based here in the UK. The process has been very straight forward.

There are other providers out there, I have tried 3. Gettested was the fastest and the customer service was the best. I even received my test on the day of purchase delivered by a motorbike courier.

I found them to be professional and not too long a wait for results. Helpful with any after questions. Will be using them again if need be. I highly recommend them.
