Weird blood results

[Katherine1234]

I had to go into hospital for a biopsy and they were concerned that my T4 is 27 and said l am thyrotoxicosis! my TSH level is 1.47 and has actually climbed from 4 months ago, it was 1.33 then. I was undermedicated for 20 years left on 50mcg of levo. Then went up to 75 mcg a year ago and 100 mcg 4 months ago. Does anyone have any idea about this weird blood results. I would be ever so grateful.

Last week after this blood test I had accidentally taken double my dose 200 mcg instead of 100 mcg. Late at night I crawled on here and found it won't do me much harm as a one off, so phew went back to bed. Strange thing is I felt really good all the next day, as I normally still feel tired and fatigued on 100 mcg. Hair still falling out too, dry skin, low morning body temperature etc.

Levo isn't quick acting, you're not likely to have felt anything the next day.

As for your results, if you can post results and reference ranges for TSH, FT4 and FT3 plus thyroid antibodies we can see if there are any clues.

The hospital did not give me any reference ranges Susie they did not do T3 either :0(

I definately felt wow! normal the next day, like normal normal after I accidentally double dosed the Levo. When they first put me on 25mcg levo, my headaches went the next daily my appetite came back. I could feel the difference straight away.

I took levo 100mcg the night before hun. I was rushed in for op pre-assessment that I did not know about so they took my bloods about 4 in the afternoon. Normally if I have a thyroid test I don#t take levo the night before.

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 Thyroid antibodies are raised

Low ferritin is often cause of hair loss

Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and fasting. Last Levothyroxine dose should be 24 hours prior to 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)

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

Ferritin, B12, Folate, Vitamin D are all optimal. I dose daily and inject B12 daily I was severely low in B12 with enlarged red blood cells. I take all co-factors too. I will have a word with my doctor but she normally won't test the whole thyroid panel only TSH. I have asked before and then the lab refuses to do the tests.

Yes, that's why so many have to test privately

It's not right, but if you want to know full results you will have to test privately

Will do darling...
