Do you also have a FT4 test result, it's very unusual to test TSH and FT3 but not FT4.

We really need to see your FT4 level then we can see how well you convert T4 to T3.

Is there a particular reason Se Ca 125 was tested, do you have fibroids or endometriosis or could you be pregnant? I think you need to discuss that with your GP.

[Knitnat in reply to SeasideSusie]

No I don't have any of them but have recently been diagnosed with RA and IBS also fibromyalgia and they usually do ft4 but nothing there am seeing go soon so will discuss

For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested.

Also EXTREMELY important to test vitamin D, folate, ferritin and B12

Low vitamin levels are extremely common, especially if you have autoimmune thyroid disease (Hashimoto's) diagnosed by raised Thyroid antibodies

Have you ever had thyroid antibodies tested!

Ask GP to test vitamin levels

You may need to get full Thyroid testing privately as NHS refuses to test TG antibodies if TPO antibodies are negative

Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .

Last dose of Levothyroxine 24 hours prior to blood test. (taking delayed dose immediately after blood draw).

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, best not mentioned to GP or phlebotomist)

Is this how you do your tests?

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

For thyroid including antibodies and 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 special offers, Medichecks usually have offers on Thursdays, Blue Horizon its more random

If you can get GP to test vitamins and antibodies then cheapest option for just TSH, FT4 and FT3 £29 (via NHS private service )

If antibodies are high this is Hashimoto's, (also known by medics here in UK more commonly as autoimmune thyroid disease).

About 90% of all primary hypothyroidism in Uk is due to Hashimoto's.

Low vitamins are especially common with Hashimoto's. Food intolerances are very common too, especially gluten. IBS is often linked to gluten intolerance

So it's important to get TPO and TG thyroid antibodies tested at least once .

You are legally entitled to printed copies of ALL your blood test results and ranges.

The best way to get access to current and historic blood test results is to register for online access to your medical record and blood test results

UK GP practices are supposed to offer everyone online access for blood test results. Ring and ask if this is available and apply to do so if possible, if it is you may need "enhanced access" to see blood results.

In reality many GP surgeries do not have blood test results online yet

Alternatively ring receptionist and request printed copies of results. Allow couple of days and then go and pick up.

come back with new post once you get vitamin and antibodies tested

Your Ft3 is very low at only 20% through range

Helpful calculator for working out percentage through range

chorobytarczycy.eu/kalkulator

Ft3 should be at least 50% through range

Likely low vitamin levels and/or high thyroid antibodies/ gluten intolerance
