From their web site. What do we think of this? Having spent a lot of money on thyroid blood tests from home and recently the Dio2 test, I'm wondering if I should beat my head against a wall or something. The rest of this article was equally depressing. But it makes me doubt myself and my symptoms.
"Beware Thyroid Test Services by Post
There is a small, but increasing, industry in the UK where private laboratories will measure your thyroid tests through a finger-prick blood sample, or in your saliva or urine. Some even offer genetic tests by post, such as the deiodinase-2 gene (DIO2) variant. These companies will suggest that these tests are better because they are ʻnot available on the NHSʼ. However, these tests are not offered by the NHS because they are unnecessary, a waste of money and the results are frequently meaningless.
One example is reverse-T3 (rT3), which is an inactive degradation product of thyroxine. Firstly, rT3 is really difficult to accurately measure because it ʻlooksʼ so similar to thyroxine. With the exception of specialist university laboratories, there is a high chance that what is calculated as your rT3 measurement is actually a highly inaccurate random number. Of course, you will have no way of knowing. Secondly, there is no situation where knowing your rT3 can usefully guide your clinical management. If it was useful, NHS labs would be measuring it."
