Hi there, my 6 year old daughter recently had her first set of blood tests after starting Levo. On Friday they were sent to me, (T4 19.4) (TSH 31) however the T3 was missing. Yesterday i got them all sent to me (T3 6) However the T4 is now showing 18.5???? I have no clue how her results could have changed? Same day/same test/same blood sample. Waiting for Paediatrician to get back to me but was wondering if anyone could shed any light please?

Were these different tests....or apparently same test...but different results

Ft4 variation is very small

Her high TSH is very odd ...considering Ft3 looks pretty high (What’s the range on Ft3 and Ft4 results?)

Same test, different results?

T4 (10-20)

T3 (5-7.3)

If they are both printed copies....it’s unexplainable

If hand written...mistakes are common
