My son who is 13 has just received his blood test result back,we live in Germany,so I hope the measurements are the same.TSH 6.08iu/ml T3 LIA 4.72pg/ml T4 1.29ng/dl.First of all,nobody can tell me ,is that under or over active,they said it is neither.He has been given L-Thyrox Hexal (levothyroxine-natrium)50 and takes one a day.Since then he feels even worse than before. Dr's said it is normal and can take up to 3 weeks,but he feels too sick to even go to school.Can anyone help explain all this to me (in English) please.
