Pregnant 2nd trimester, still lowTSH but normal T3 & T4, Positive TRab

[Renriz]

Feeling a bit better now appetite is good but new lab tesults are becoming confusing.

Renriz,

TSH is very suppressed but you haven't included the FT4 and FT3 lab ref ranges so I can't tell whether they are high in range or not.

Renriz,

Welcome to our forum and congratulations on your pregnancy.

TSH needs to be kept low to enable a good thyroid hormone supply to baby as is critical to normal development of the baby’s brain and nervous system.

Positive TRAb indicate thyroid receptor antibodies. Do you have any previous thyroid issue history ? ?

If you post any further test results complete with ranges (numbers in brackets) members will comment.
