Please help me understand my blood work and symptoms
I’ve been struggling for the longest time with fatigue, stubborn weight, and feeling extremely cold + sluggish, constipated and having ED. I’ve been taking my oral temperature on waking and throughout the day. Waking temp ranges from 92-96 (usually around 94). Highest I’ve ever gotten my oral body temp is 97.
I did a series of blood tests that revealed the following:
TSH: 0.85 (range 0.4-4.5 mIU/L) T4 (total): 6.5 (range 4.9-10.5 mcg/dL) T4 (free): 1.1 (ref range 0.8-1.8 ng/dL) T3 (total): 71 LOW (ref range 76-181 ng/dL) T3 (free): 2.7 (ref range 2.3-4.2 pg/mL) Reverse T3: 20 (ref range 8-25 ng/dL)
When I’ve repeated this test in the past (not the full comprehensive set), my rT3 came out high once but my total T3 has always been low.
- How can my free T3 be normal but total T3 low? Is it because I have very little binding protein?
