BACKGROUND: The aim of our study is to compare the markers and parameters obtained from complete blood count between patients diagnosed with missed abortion in the first trimester and a healthy pregnant control group.
MATERIALS AND METHODS: This descriptive, retrospective, case-control study included 166 patients diagnosed with missed abortion according to ultrasound criteria, and an equal number of healthy pregnant controls, who visited the Gynecology and Obstetrics Clinic at a Training and Research Hospital from January 1, 2018, to July 1, 2023. Participants, with 5 to 14 weeks of gestation, were selected using simple random sampling. Data on age, gravida, parity, gestational week, and hemogram results were retrieved from medical records and compared. Statistical significance was set at p < 0.05.
RESULTS: No significant differences were observed between the case and control groups in terms of gravida, parity, age, or gestational week (p > 0.05). Likewise, comparisons of hemogram parameters and derived values, did not show statistically significant differences (p > 0.05). However, the multivariate logistic regression analysis revealed that each unit increase in lymphocyte count was linked to a 2.075 times higher risk of missed abortion (p = 0.040).
CONCLUSION: Our study found no significant differences in complete blood count parameters between the missed abortion and healthy pregnant groups. Although lymphocyte count was significant in the multivariate model, this association should be interpreted with caution, as complete blood count values were obtained at the time of diagnosis. Therefore, it does not indicate predictive value, and prospective studies are needed to determine whether lymphocyte count may serve as a pre-diagnostic marker.
