What time of day to get tested?

July 22, 2003

When I was taking my Armour once a day I would always get tested at

around 3PM anytime I was tested to make sure I stayed consistant.

Since I have split my dose in half (half at 8 am other half around 2

pm) I do not know when to get tested for the proper levels.

Everyone says the main thing is the Free T3 and Free T4. For this to

be acurate should I be tested in the morning right before my morning

dose? Would this be an acurate way to determine if the T4 or T3

portion of my meds. is too high or low? This will probably show me as

hypo on my TSH though as the way I feel seems to improve as the day

progresses but as I have heard you go more by how you feel on TSH and

if I feel right this hould be ok. I guess I am mainly concerned with

the Free T3 and Free T4 and what time of day I should get tested.

Thanks

Hi,

TSH lags at least 6 weeks behind your thyroid hormone levels so it won't be

affected by your dose. Thyroid levels are best drawn in the morning before 10

am, and you should wait to take your am dose that day or your FT3 will appear

falsely elevated. Take care, Elaine
