Help understanding

I have every symptom going for Under Active Thyroid

i had a routine annual blood test 3 months ago and one of them was my TSH Level which came back 4.72 Miu/L . My doctor asked me to come back in 3 months which i have done whilst struggling to get on with each day due to not feeling well.

so i got my results today and they say 2.71MIU?L and it states Satisfactory !!

Now i have insisted that my doctor phone we as i cant just make an appointment to see them , you have to wait for them to phone first. so whilst im waiting i was wondering what your thoughts are and can anyone tell me what the levels should be ?? its driving me nuts

any help would be appreciated x

    TSH 2.71 is satisfactory in the sense it is within the lab ref range but it does indicate your thyroid is beginning to struggle. NHS won't diagnose hypothyroidism until TSH is over range.

    Protocols state that the first abnormal thyroid result may be elevated due to a virus or infection at time of testing and that it should be retested in 3 months to rule out non-thyroidal illness when the virus or infection is expected to have resolved.

    If you tested at different times of day that may account for the variation in results. TSH fluctuates according to circadian rhythms and is highest early in the morning and lowest in the afternoon and evening. Members are recommended to have a blood draw early in the morning when TSH is high and to fast (water only) as TSH drops after eating and drinking.

    Another reason for fluctuation in TSH results is autoimmune thyroid disease (Hashimotos). Ask your GP to include thyroid peroxidase antibodies next time you have a thyroid test.
