Blood test taken on 13/11/18 at 3:30pm.
Had I know they were going to test my thyroid I would have requested an early morning appointment and not taken my levothyroxine 100mg that on the day of the test either.
Tests results are:-
Serum TSH level 0.09 mu/L [0.35 - 3.5]
Below low reference limit
Serum free triiodothyronine level 3.9 pmol/L [3.8 - 6.0]
Serum free T4 level 17 pmol/L [8.0 - 21.0]
Blood test taken on 10/07/2018 at 8:30am
I booked the earliest appointment they had and missed my morning dose of 100mg of Levothyroxine until after the blood test was taken.
Serum TSH level test and the results were:-
Serum TSH level 0.74 mu/L [0.35 - 3.5]
As you can see my serum TSH level was within range in July 2018 but out of range in November.
As a consequence the GPs receptionist called me this morning and said my November blood tests were too low and they have already written a new prescription for 75mg Levothyroxine.
As I feel absolutely fine at the moment I told the receptionist that I wasn’t happy lowering the dosage, stating what everyone recommends in the group "having a blood test early morning and delay taking the Levothyroxine on the day until after the blood test is taken, otherwise the results aren’t accurate". She said she will type a note to that effect and see what the GP says.
I should also add that I have been tested positive for Autoimmune Thyroid Disease or Hashimoto's disease as it’s commonly referred to on here.
I would just like to know if anyone else thinks I’m right in asking to remain on 100mg Levothyroxine.
