Coronavirus infection (COVID-19) is a global public health issue at the present. However, previous research on the results of COVID-19 blood tests in pregnant women is inadequate. the goal of the study: The goal of this study was to study some biochemical tests in pregnant women in Mosul, Iraq, who had COVID 19 infection. A case-control research involving 331 pregnant women (113 with COVID-19, 110 without COVID-19, and 108 healthy non-pregnant women) who paid to visit a private laboratory in Mosul, Iraq from the date of 15/11\2021 to 15/1 2022. All patients have already been diagnosed with COVID-19 and they have symptoms and signs. Each of the patients and healthy controls had their whole blood samples collected to be analyzed for; serum ferritin, GOT, and GPT. Also analyze lipid profile as Total cholesterol, T.G, HDL-c, LDL-c, and VLDL-c. The large percentage of pregnant women with Covid-19 had greater levels of serum ferritin, ALP, and lipid profile than pregnant women without Covid-19, according to the current study. In addition, pregnant women who had Covid-19 had lower serum GOT and GPT levels than pregnant women who did not have Covid-19. Infections with Covid-19 may elevate the levels of serum ferritin, ALP, and lipid profile. As a result, it's necessary to keep a check on these biochemical parameters, especially in those who have severe Covid-19 infection.
