Maybe you can teach me something here! I just pulled out an old lab report that was done in 1999. Doctor back then never mentioned me having any thyroid problems on this lab. The only thing this lab reads is the TSH level.
Normal range back then was (0.35-5.50) My TSH back then read 0.39 showing no negatives or positives. The endrocrine doctor did some labs before surgery and I don’t have the results but I wrote them down before leaving the lab and asked the lab technician what they all were. At that time he did a TSH, T3, T4, Vitamin D25, TPO, TSI,CMP,HGB A/C, Glucose, Hyperglycemia, CBC, WBC. He said my TPO and TSI came out positive for Graves Disease. And said I was hyper! So is Hyper being more towards the low end and Hypo on the higher end! A 4 would be within normal limits just like my lab is 1999 0.42 was on the lower end but within normal range. Am I correct?
