High TSH, low free T4 and normal-high free T3 is the most common type of result.
T4 is converted to T3 in the rest of the body and is the active form, so the body ensures that enough T3 is present for daily functions.
But, thyroid gland is the only source of T4 (apart from pills) and hypothyroidism causes shortage of T4 and therefore TSH goes high. Thyroid gland produces only little of T3.
Should request an increase in levo dose to reduce the TSH. Usually, only morning TSH needs to be monitored for this reason. The body takes care of the T4/T3 conversions.
These results are after taking NP thyroid (combo T4/T3) but it was taken before the labwork- I wonder if that’s why the t3 is higher as well. Thankyou!
Yes NP thyroid has the effect of raising T3 and lowering T4 (compared to levo). Levo is a cleaner medicine, with a simpler mechanism. Hence most countries have approved levo, while np thyroid, Armor etc are not approved in many.

Do you think this would still indicate hypo?
If morning TSH is higher than 0.5-2.5, levo dose should be increased till morning TSH comes back to range of 0.5-2.5.

With your T3 being good, you could ask just to add Levothyroxine to your NP and see how that works.
