I have had a private blood test, which showed far more information than any that have been requested by my GP.
Free T3 3.7 range 3.1-6.8 pmol/L
Thyroid Peroxidase antibody 8.0 range 0-24 IU/ml
TSH 3.380 range 0.27-4.20 mlU/L
Free T4 10.82 range 12-22 pmol/L
Iron 5.7 range 5.83-34.5 µmol/L
Transferrin saturation 9.1 range 15-45%
Ferritin 5.66 range 13-150 µg/L
Serum Folate 5.60 range 3.89-26.80 ng/ml
Vitamin B12 347.2 range 197-771 pg/ml
Vitamin D 50 range 75-200 nmol/L
I have been taking 125mg Levothyroxine daily, for last 6 years and took last dose 24hrs before blood test.
I had the blood test after 10 hour fasting and at 8:30am.
I'm 58 and feel more like 108! Constantly tired, depressed, breathless after the smallest task - like walking up a flight of stairs - resting pulse is around 55, but huge spikes on moving about.
All help and advice is extremely welcome.
