For full Thyroid evaluation she needs TSH, FT4, FT3 plus TPO and TG thyroid antibodies and also very important to test vitamin D, folate, ferritin and B12
Go back to GP and ask for thyroid antibodies and vitamin testing
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
All thyroid blood tests should ideally be done as early as possible in morning and fasting. This gives highest TSH and most consistent results. (Patient to patient tip, not to be mentioned to GP or phlebotomist)
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 hypothyroidism in Uk is due to Hashimoto's.
Low vitamins are especially common with Hashimoto's or Graves .
Food intolerances are very common too with both, especially gluten. So it's important to get TPO and TG thyroid antibodies tested at least once .
Thanks for your reply. I did tell the GP I wasn’t convinced this is normal, due to her symptoms and he has agreed to re test her in a month and include antibodies, folate and B12, plus diabetes check. So will see what comes back.
In hypothyroidism (low thyroid function - which causes weight gain, hair loss, fatigue etc.) the TSH tends to become elevated (if the thyroid gland isn't working as well) whilst T4 and T3 levels drop. While the 2 blood tests could just be fluctuations (time of day, different stressors nearly 2 years apart), a small drop in a patient with family history of thyroid disorders should be monitored.
Hopefully the further testing by your GP or privately through e.g. Medichecks, will shed some light.
There is some evidence that, where someone is preclinically hypothyroid (slowly declining gland function, with hormones still in range), starting with low dose (25-50mcg) thyroxine can be helpful in abating initial symptoms. This should be discussed with your GP or another medical professional.
