Ferritin - 40ug/L range 15-150ug/L slightly lower than before.
Folates 4.7ug/L range 4.6-18.7ug/L slightly lower than before.
Vit B12 310ng/L range 191-663ng/L slight raise.
TSH 7.01mlU/L range 0.3-3.94mlU/L down from 10.23mlU/L
fT4 12.2pmol/L range 12.3-20.2 up from 10.1pmol/L
Vitamin D 26nmol/L range 25-50nmol/L = insufficient. Secondary hyperparathyroidism likely.
I have not taken iron supplements but was taking vitB complex containing 500ug B12 and 400ug folic acid have been taking them on and off for years. Also had been taking Vit D at 4000iu per day for 7 weeks before the test. So a bit disappointed with those results.
Any advice please?
