New to Thyroid -- what does this mean?
I'm new to thyroid problems. My doc has ignored my requests to include T3 values in my blood tests so I found out a way to order my own tests and now I have some data. Do these values seem to indicate an underlying issue with T3 conversion or not? I have to wait 2-1/2 months to see my new endocrinologist. Was hoping for some insight.
TSH: 1.51
Free T4: 1.3
Rev T3: 22
Free T3: 2.8
I had been on Levothyroxine for 2 months, but I took this blood test on the day of my final dose. I am now off all thyroid meds because they were making me feel increasingly worse.
Thanks,
Deb

Pre-medication:
TSH 2.800 uU/ML 0.340 - 5.600 uU/ML
I was subclinical, but had other concerns such as higher glucose, cholesterol, blood pressure, and weight problems. The plan was to treat the thyroid issues in order to reduce the other factors. It made sense.
My previous lab results 6 weeks after starting medication (no T3 values were tested)
TSH 0.910 uU/ML 0.340 - 5.600 uU/ML
T4 FREE 1.08 NG/DL 0.61 - 1.81 NG/DL
Looks good, right? Except I felt absolutely awful.
While I was on the meds it became increasingly difficult to function, which is why I stopped. I understand the need for time in order for everything to level off, but something was seriously not right and was getting progressively worse each day. Unfortunately, my regular doc doesn't seem to believe in T3 tests or meds which is why I'll be seeing an endocrinologist.
Sincere thanks for the insight. I'm trying to learn everything I can.

Oh! I'm sorry. I didn't realize there was a variation from lab-to-lab.. Here are the corrected results with the ranges and units included.
TSH: 1.51 mIU/L ( 0.40-4.50 )
Free T4: 1.3 ng/dL ( 0.8-1.8 ng/dL )
Rev T3: 22 ng/dL ( 8-25 ng/dL )
Free T3: 2.8 pg/mL ( 2.3-4.2 pg/mL )
At the time I was on 50 mcg of Tirosint daily.

So, in these labs, your FT4 is right where it should be at 50% of range. However, your FT3 is low of the 50+% guideline. It's only 26% of range. That could indicate a conversion issue. Since you'd only been on meds for a couple of months, it could also indicate that your body is still in the rebalancing process.
You calculated correctly. Your FT3:RT3 ratio is 12.7. That's a little on the low side. Most people say it should be over 20.0...my personal opinion is that upper teens is probably fine.
Your system is still in flux. You could continue T4 meds and see if conversion ramps up (my FT3 kept climbing for quite some time after my FT4 reached a stable level), or you could try adding some T3 to your meds.
