Advice: Blood Test and Ultrasound Results

[ahuff89]

This is what I have after bloodwork and ultrasound from last week (January 17, 2019):

TSH is low (0.01) - This has been the same during my past 3 labs since August 2018

Total T3 High (284, august it was 264).

T3 Uptake is Normal (How can that be is Total T3 is not?? Confused)

Thyrogloblulin high (83 IU/ML) - Only tested in August, and not during recent visit.

Everything else in blood work is normal (liver, kidney, Vitamin D, blood count, T4).

Dr. says large left nodule (I've been told goiter in past) is measuring 4.5 cm and partly solid, which is what is was 7+ years ago.

It's cystic with smaller nodules on both sides.............. Going to get a Radio active Iodine test this week, but would love other opinions as I am holistic. Dr says RAIU is needed to determine if it's Graves or if it's Thyroiditis.

Either way I think I need to get on a better diet (AIP diet) as food does cause me pain and fatigue.

The T3 Uptake test estimates the amount of thyroxin-binding globulin (TBG) in the blood, a carrier protein that transports the T4 and T3 hormones. Only the T4 and T3 that is "free" of the protein is available to the cells, hence 'FreeT4' and 'FreeT3'. The test therefore helped assess how much of the Total T4 and Total T3 was likely to be available; but now of course, we have tests to directly measure FT4 and FT3 so the uptake test is not needed, and the Total test is likewise not really necessary either.

Thank you for explaining that. Very helpful
