Thyroid functions in pre-eclampsia and its correlation with maternal age, parity, severity of blood pressure and serum albumin.

Maternal thyroid function was investigated in 32 pre-eclamptic women and 10 normal pregnant women in their third trimester. Serum total tri-iodothyronine (TT3) and total thyroxine (TT4) were decreased significantly (P < 0.001) and TSH was increased significantly (P < .001) in pre-eclampsia as compared to normal pregnancy. There was no influence of parity and maternal age on thyroid functions. TT3 and TT4 decreased significantly (P < .001) with increase of serum albumin, while there was no correlation of TT4 with serum albumin.
