If you have already have a Cyrex, Nationwide Pathology, FDX, or other, blood test kit, you can book a blood draw through Phlebotomy services with or without centrifugation.

FDX Thyroid Check

According to the British Thyroid Foundation, 1 in 20 people in the UK suffers from thyroid disorders. However, this doesn’t tell the whole story as often thyroid disorders go undiagnosed. Why? Doctors believe this could be down to 2 main reasons. Firstly, mild cases of hypo- or hyperthyroidism don’t necessarily have symptoms, and secondly, when they do, they appear so slowly, that people misattribute them to other things. 


Price includes all the phlebotomy services, centrifugation, refrigeration, transport, analysis and a comprehensive, accurate and clear report.

How it works

Wait up to 5 days to receive your test kit.

Once received, book an appointment online, for a blood draw. Our Phlebotomist will guide you throughout the process. How to prepare.

Undiagnosed thyroid disorders can create a greater strain on various bodily functions. Thyroid imbalances can often go undetected when certain crucial markers are not taken into account during testing. 

Identifying thyroid dysfunctions can reveal key information on imbalances within skin and hair, support weight management, and drastically improve mood and energy levels. 

Suitable for:

  • Those that have shown signs and symptoms of a dysfunctional thyroid including lack of energy, body temperature disorders, hair loss, weight gain, gut motility and more.
  • Those needing to identify a hypothyroid or hyperthyroid status.
  • Those looking to improve image, mood and quality of life.


Our comprehensive Thyroid CHECK offers the full spectrum of thyroid markers including T4, free T4, T3, Free T3, Reverse T3, T3 Uptake, many ratios and also includes glucose and a full blood count to accurately identify and ‘ check’ for subclinical disorders and help assess thyroid gland function.
