This study aimed to investigate the prognostic value of serum melatonin as a biomarker for the determination of severe COVID-19 infection in pregnant women.
Four study groups were formed, including pregnant women with a positive COVID-19 PCR test, severe symptoms, and inpatient treatment. Pregnant women who had complaints similar to COVID-19 infection or had no complaints, but had a PCR test due to the surveillance program and negative test results were included in the control group.
Methods and Main Outcome measure: Laboratory values of the cases at the time of diagnosis parameters were collected.
Melatonin levels decrease in pregnant women with COVID-19 symptoms, the severity of symptoms increases. In addition, patients with low melatonin levels have an increase in infection parameters and an increase in the hospital stay.

Inclusion Criteria:
- pregnant women with a positive COVID-19 PCR test and severe symptoms and inpatient treatment. Pregnant women who had complaints similar to COVID-19 infection or had no complaints but had a PCR test due to the surveillance program and negative test results were included in the control group. Pregnant women who had contact with people with COVID-19 infection and had a PCR test due to the surveillance program and had positive results, but no complaints were included in the other study group. The PCR test of pregnant women who had complaints and needed inpatient treatment during the COVID-19 infection was confirmed, and the COVID-19 infection was graded according to WHO's criteria. Pregnant women with viral infection with symptoms compatible with infection and virus isolation in any culture samples collected at admission were included in the patient group with PCR positive mild-moderate and severe COVID-19 infection.
