Levothyroxine 50 mcg....10.mcg.Liothyronine( T3)

[ltjardes05]

Can anyone give me advice on lab results? TSH..0.78. FREE T4...0.70. FT 3...2.7...

we need ranges on results too please

Also EXTREMELY important to test vitamin D, folate, ferritin and B12

Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .

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

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, best not mentioned to GP or phlebotomist)

If/when also on T3, make sure to take last third or half of daily dose 8-12 hours prior to test, even if this means adjusting time or splitting of dose day before test

Is this how you do your tests?
