Hello, im travelling from Gloucestershire to London on tues for a blood draw at 12 noon. I won't take my levo the night before as usual and wait until after the draw but can i have a cup of tea and a few brazil nuts at around 8 am or will that skew the results? Im not worried about the food impacting the absorbtion of the levo for that day just if it will impact the blood results in any way.
My t3 was low in range last time and t4 was good. I have taken mercury pharma ( eltroxin and unbranded) for 9 years or so but for last 3 months ive been taking Activis. I feel a bit undermedicated even though im now taking 150 mcg. Ive put on a stone in weight but im also using bio identical hormones for hot flushes so could be that. I use a transdermal cream with estrogen, prog and test morning and evening and now take my levo in the middle of the night so there is a four hour gap between.
I will get my ferritin, vit d and b12 tested too although they were all high in range last time. I guess im wondering if the bio identicals are impacting my t4/t3. Ive always been at the lower end of the range for t3 and t4 has always been high in range. Will post results when i have them.
