Hi,
A TSH of 1.93 would normally not be considered hypothyroid (latest reference range is somethinng like 0.5 - 3.0).
Did you have other test results that may indicate hypothyroid? Please post results and reference ranges. Do you have symtoms?
Actually the TSH 3rd generation test is not being used hardly anymore. It's really a non - responsive test to understanding low thyroid function.
I seriously wouldn't go by that lab to determine anything. Knowing your history a bit more may help as said above.
If you want a more reliable look at if you have hypothyroidism, consider looking up symptoms and get the Free T3 and Free T4 thyroid labs checked.
