hello everyone
I had a under active thyroid for 30 years or more. Just took medication and thought nothing more until I was due to have surgery. I didn’t know how important it was. Need another blood test and surgery is postponed. Had surgery before and thyroid test was normal. Can anyone tell me what blood test should be for surgery age 59 years female. MyTSH level is 7.7 at this time.
many thanks for your time.

Welcome to the group.It's likely that they would want your TSH at least within the normal range. How do you feel? Have you changed anything about how you take your Levo? Is that always on an empty stomach 1 hour away from food or caffiene drinks?
Has your doctor increased your dose?
When hypo we get low stomach acid that means we cannot absorb vitamins well from our food. For thyroid hormone to work well we need OPTIMAL levels of vitamins. Have you recently or could you ask your GP to test levels of ferritin, folate, B12 & D3?
This did actually happen to me but luckily it was long enough pre surgery that I could get my levels back to normal.
Welcome to forum
The TSH is a pituitary hormone. It signal thyroid to produce. When it’s in range it usually means FT4 or FT3 the thyroid hormones - the free thyroxine the active triiodothyronine are also in range.
So a TSH of 7.7 is over range & it’s likely FT4 & FT3 are low and you need an increase in medication.
Any changes recently eg to weight, or diet or level of activity?
Any stomach issues which may cause absorption issue?
Any changes to other medication or supplements or how you take your replacement or time of taking replacement, or new brand?
See what doctor has tested as TSH alone doesn’t give you enough information. You are legally entitled to results. Online access is useful, but takes time to set up if offered. You can obtain print outs from reception. Must be printout with lab ranges (ranges vary so always needed)
For full thyroid test you need TSH, FT4 & FT3. Thyroid antibodies TPO & TGab. (May not have been tested since diagnosis). Also important to test folate, ferritin, B12 & vitamin D. Especially prior to surgery of any sort as you need a benchmark for after surgery results.
Many use private home fingerprick tests to test everything as GP often won’t test everything.
For thyroid testing - for consistency it’s recommended you fast overnight, book draw for close to 09.00 and delay replacement until after draw. Stop any supplements containing biotin 3 days before as biotin can skew results.
