Hello I have been posting about my sister who has been treated!!!!! For hypothyroidism for 25 years .She is currently struggling with low ferritin levels and feeling very tired Dr only checking TSH and only ever has over the years and say all good .She had a test at Blue Horizon with results as follows--
Total Thyroxine(T4)113 nmol/L 59--154
TSH 0.84 mIU/L 0.27--4.2
Free Thyroxine19.9 pmol/L 12.0 --22.0
Free T3. 3.6. pmol/L. 3.1--6.8
Thyroglobin Antibodies. 14.5. 0-115(negative)
ThyroidPeroxidaseAntibodies. 11.1. 0-34. Roche Modular method.
Would you say that there is a conversion issue as her T3 is low , but normal in range or is the T3 ok and wouldn't cause the symptoms . I understand low ferritin stops conversion of Thyroxine ..She takes 100 mcu daily away from food iron tabs etc ...Dr has dismissed her said all normal ...is there a case for trying to add T3 or pos changing to NDT ..She saw Dr P last year and was taking adrenal treatment ,if she ups her Throxine she gets shaky and anxious so 100 is tops .What would be your opinion \ advice at this stage .With grateful Thanks Val
