When you did yor Medichecks test, did you include Thyroid Antibodies? If not I would retest to include Thyroid Peroxidase and Thyroglobulin antibodies. You could also mention this to your GP and see if they will test them, possibly wont in which case get them done with Medichecks - Thyroid Check Plus

but if you do a new Medichecks test it would be much better to include vitamins and minerals as these are also important so I'd go for - Thyroid Check UltraVit.


It is a huge error in the UK that whoever made the decision not to diagnose until the TSH reached 10 must be suffering from hypo as they cannot appear to think straight.

In other countries we are diagnosed if the TSH goes above 3. The fact that doctors also are ignorant of clinical symptoms - befor the blood tests and levo were introduced doctors knew all clinical symptoms. That's why many on this forum source their own in order to be well rather than consult with ignorant doctors/endocrinologists.

All blood tests have to be at the very earliest, fasting (you can drink water) and if you were taking thyroid hormone replaements you'd allow a gap of 24 hours between last dose and test and take afterwards. The TSH is highest early a.m. and drops throughout the day and can mean a difference between being diagnosed or not.

We have two labs that will do home pin-prick tests and if you decide to do so make sure you are well hydrated a couple of days before blood draw.

You need, TSH T4 T3, Free T4, Free T3 and thyroid antibodies.

GP should test B12, Vit D, iron, ferritin and folate.

Doctors and endocrinologists seem to be very badly trained that they are incapable of 'looking' at a patient and diagnosing - which doctors used to do before they introduced levothyroxine/blood tests. Before that we were given NDT (natural dessicated thyroid hormones) on a test trial and if we improved we stayed on them and were diagnosed.


Medichecks and Blue Horizon are the labs. Medichecks does an offer of some sort every Thursday.

No didn’t do antibodies will get that done thank you my gp checked all vitamins iron etc everything was normal it’s just the difference between medichcek result and gp but medicheck was done first thing in morning and gp was in afternoon so that might have made a difference thank you

Always get a print-out of your results with the ranges. 'Normal' to doctors isn't necessarily the same as 'optimal' and that is what we want 'optimal'.

A.M and P.M blood tests will be different and are not to the patient's advantage and may result in not getting the dose our body requires.


For full Thyroid evaluation you need TSH, FT4, TT4, FT3 plus TPO and TG thyroid antibodies and also very important to test vitamin D, folate, ferritin and B12

Ask your GP to test Thyroid antibodies and vitamins

Private tests are available. Thousands on here forced to do this as NHS often refuses to test FT3 or antibodies or vitamins


Medichecks Thyroid plus ultra vitamin or Blue Horizon Thyroid plus eleven are the most popular choice. DIY finger prick test or option to pay extra for private blood draw. Both companies often have money off offers.

All thyroid tests should ideally be done as early as possible in morning and fasting. This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, GP will be unaware)
