Hello I am new, and don’t understand my levels, the doctor said my thyroid is slightly under active, but not going to do anything and to have another test in 6 months, I have been suffering with a few symptoms of an under active thyroid, but I thought it was my B12 levels as symptoms are the same and I’ve had low B12 before, My T4 level is 12.9 but not put a range, and my TSH is 5.78 in range (0.35-5.5). But I do not understand it, please help. X
Also my Folate is 5.7 and ferritin is 44.9, B12 350ng/l

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 and most consistent results. (Patient to patient tip, GP will be unaware)
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
Hi I understand the T4 range is 11-24 (if I am wrong I am sure someone will correct me) so yours is low. Mine was 11.7. I have some symptoms of hypor but the doctor said it is only borderline and recommended another test in 3 months. x
