Blood results help

[George303]

Anyone exsplain this blood test changs.

Cut a long stoty down started 50mg thyroxine on it for around 2 months it helped but no enought at first. Doctor agreed it my choice to increase to 100mg. Discovered over treating as shown below so told to lower dose to 50mg again but tsh has only increased by 0.01?

Start levo 50mg had a blood test 40 days later.

4th feb 2019 on 50mg levo

Free t4 19.6

Tsh 2

Free triiodothyronine T3 5.7

Started 100mg levo felt better around end 22nd march.

25th april 2019

Free thyroxine 31 told too hight ....

Tsh 0.01 this is the one which you will see below.

50mg levo blood 26th may.

Tsh 0.02 mu range 0.3 -4.2 ???

Ft4 20.3 range 12.0-22.0

Ft3 6.6 range 3.1-6.8

Should the tsh have gone towards 1-2 like previously been on 50mg as the ft4 has came down from 31 to 20.3?

I'm guessing you have Hashi's. These look like Hashi's swing results. Have you had your antibodies tested?

[greygoose in reply to greygoose]

Oh, and you shouldn't being increasing/decreasing by 50 mcg at a time. Not more than 25 mcg every six weeks.

thyroid peroxidase abs done on 16jan ... result <9 0-34 ..

As another person recommend i need my tg antibodies checked which i will ask for. Try telling me my gp something its like talking to a brick wall tried to make me drop from 100mg to 25mg at first.

[greygoose in reply to George303]

Oh dear. He doesn't know anything, does he. I doubt he'll do your Tg antibodies, most people get them done privately. But, you can have Hashi's without ever having high antibodies.

Dose of Levothyroxine should only ever be increased by 25mcg

Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and fasting. This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, best not mentioned to GP or phlebotomist)

Last Levothyroxine dose should be 24 hours prior to test, (taking delayed dose immediately after blood draw).

Is this how you do your tests?

Ask GP to test vitamin D, folate, ferritin and B12

Frequently these are too low and need supplementing to improve

Low vitamins common ESPECIALLY AFTER A DOSE REDUCTION in Levothyroxine

There are lots of good PILL cutters around so relatively easy to cut a 50 to give you the 25 mcg. It's best to do that than source a 25 mcg by a different brand. Brands can vary slightly in potency so best to stick with that but even a 25 of the same brand can also vary slightly but Levo is a storage hormone so ok to use a cutter. When I first started out the Pharmacist always gave my whole dose in 25's to make it easier for me.
