Abstract
Background and objectives: In patients with coronavirus disease 2019 (COVID-19), white blood cell (WBC) abnormalities have been found worldwide with significant inter-regional differences. In the present study, we evaluated WBC parameters concerning COVID-19 positivity and severity.
Methods: In this cross-sectional study, total WBC count, absolute count of each type of WBC, neutrophil to lymphocyte ratio (NLR), and lymphocyte to monocyte ratio (LMR) were compared between 150 COVID-19 patients and 150 non-COVID-19 patients presenting with COVID-19-like symptoms. Also, COVID-19 patients were divided into severe and non-severe cases.
Results: The severity of the disease had no significant association with age or gender (p>0.05). Total WBC count, absolute neutrophil count, absolute monocyte count, and NLR were significantly lower (p<0.05), while LMR was significantly higher in COVID-19 patients compared to non-COVID-19 patients (p<0.05). Total WBC count, absolute neutrophil count, and NLR were significantly higher (p<0.05), while absolute eosinophil count and absolute lymphocyte count were significantly lower (p<0.05) in severe COVID-19 patients compared to non-severe patients.
Conclusions: Age is not a predictive factor for the severity of COVID-19. Routine WBC parameters are useful in predicting the severity of the disease in COVID-19 patients and can be used as prognostic indicators. Routine WBC parameters can also be used for repeat RT-PCR testing in COVID-19 suspected patients.

Abstract
Background: The ABO and Rh blood group systems have been associated with variations in disease susceptibility. This study aimed to assess the variability in blood parameters, including red cell parameters and metabolic parameters (Renal function, hepatic function, blood glucose, lipid profile, and thyroid function), by ABO and Rh blood grouping systems.
Methods: A secondary data analysis was conducted among patients who underwent a preventive health check-up at a private tertiary care hospital in Coimbatore, India. The laboratory database contained records of 62,808 adult participants who reported for master health check-ups between January 2017 and February 2024. Among these patients, those who reported for the first time were included.
Results: Blood grouping and typing data were available for 50,368 and 56,155 participants, respectively, with a mean age range of 52.6 to 53.0 years across all blood groups. The most prevalent blood group was O, followed by B, A, and AB, with a similar distribution across genders. The mean hemoglobin level was highest in the B group (13.7 ± 13.9 g/dl). MCH and MCV values were elevated in the A and O groups, while MCHC and ESR were higher in the B and AB groups. Renal and liver parameters mostly did not vary by blood group or Rh type, except for elevated urea levels in the A group and higher ALP levels in the O and Rh-positive groups. LDL and total cholesterol were highest in the A group, while HDL was highest in the AB group.
Conclusion: The results underscore the importance of considering blood group variations when interpreting blood parameters in clinical practice.
