This study investigates the associations of ABO blood groups on long-term COVID patients who applied to the COVID-19 Fol- low-up Center. New co-morbidities after COVID-19 were also evaluated. Methods: This study was designed retrospectively with patients admitted to COVID-19 Follow-up Center between December 13, 2020, and November 1, 2021. The study sample consis- ted of 502 patients divided into four groups according to their blood types. Patients were analyzed according to their symptoms and our findings after COVID-19 by blood group variable. Newly diagnosed co-morbidities were recorded from patient’s files, and the drug history of the patients was investigated A total of 502 COVID-19 patients were retrospectively analyzed, and the mean age was 55.5(±13.2) years. Patients were predominantly female (263/502) (52.4%). While long-term COVID-19 symptoms were observed in 76.9% of the patients, extreme fatigue (46.2%) and ongoing shortness of breath (32.9%) were observed most frequently. No relationship was found between other prolonged symptoms of the disease and blood groups except heart palpitation with blood groups A and B compared to AB and O (p=0.048) . In addition, there was no significant difference in the ongoing symptoms and inflammatory parameters like C-Reactive Protein and Lymphocyte count. This study demonstrated no difference between blood types and long-term COVID-19 patients' clinical features.
