Pregnancy-induced hypertension (PIH) is a major pregnancy complication that causes pregnant women mortality. Here, we had scrutinized the correlation between serum levels of -hCG and biochemical parameters in PIH. Serum samples were collected from eighty Iraqi women (forty women with pregnancy-induced hypertension as patients group, twenty normotensive pregnant women as a positive control, and twenty normotensive non-pregnant women as a negative control) all groups were diagnosed clinically. All -hCG hormone level was measured for all studied groups, also serum uric acid, albumin, and total protein levels were measured as biochemical parameters. Data analysis showed that serum level of -hCG hormone was significant increase (p≤0.05) in PIH in compared to control groups. Also Uric acid level was increased significantly in PIH group in compared with control groups. While Albumin show there was no significant difference in PIH group. Total serum protein level was measured by Bradford total Protein assay all results was in normal value and showed a significant difference in PIH group in comparison to control groups. Our study shows that there is correlation between β-hCG with uric acid and albumin levels in PIH. Serial estimation of serum β-hCG, uric acid, and albumin can be important to use as a marker of disease and also can be used in better early management of established cases that lead to preeclampsia and eclampsia.
