The current study included the collection of 90 serum samples to assess the relationship between the level of Fetuin-A, and some biochemical variables in women with polycystic ovarian syndrome. The samples were collected from external laboratories in Salah El-Din Governorate for the period from 10/29/2021 to 12/25/2021. 60 samples of women with PCOS and 30 samples representing the control group, their ages ranged between (18-40) years for patients and healthy ones. Fetuin-A level and lipid profile were estimated in the blood serum of groups for both of women with PCOS and healthy women as a control group. The results of the study showed that the level of Fetuin-A was significantly increased at (P≤0.05) in women with PCOS compared to healthy women as a control group, and the results also showed a significant increase (P≤0.05) in the cholesterol level, Triglycerides, low-density lipoproteins, with no significant difference in the level of high-density lipoprotein- and very low-density lipoproteins in women with PCOS compared to healthy women as a control group.
