In confirmed positive patients, the purpose of this study is to assess the relationship between Coronavirus Disease 19 (COVID-19) and the primary complete blood count (CBC) parameters. In a retrospective cross-sectional study, 192 files of patients with a confirmed diagnosis of COVID-19 who were being treated at Govt medical College &Hospital Rajouri in India were randomly chosen as a study group for haematological parameters, and an additional 192 files of patients without a confirmed diagnosis of COVID-19 whose medical histories did not include any conditions that might have an impact on their haematological profile were chosen as a control group. The control group's gender, age, and nationality were matched to those of the study group. In contrast to COVID-19 negative patients, anaemia and thrombocytopenia weresignificantly more common in COVID-19 positive patients.However, the prevalence of leukopenia did not differ statistically between the two groups, but the positive individuals were 3.4 times more likely to be anaemic and around 5.3 times more likely to be thrombocytopenic. The median values for mean cell volume (MCV), total white blood cell (WBC) count, lymphocyte count, and basophil count between the two groups, however, did not indicate any statistically significant differences. Further research is advised to corroborate these findings because severe positive individuals may have highly developed anaemia and thrombocytopenia.
