Impact of Age and Gender on lymphocyte subset counts in patients with COVID-19

While lymphocytopenia in COVID-19 patients is well known, the influence of age and gender has hardly been considered so far. The aim of this study was to analyze the influence of age and gender on the total number of lymphocytes, as well as on B-, T- and NK- cell subsets during COVID-19.
Conclusion:
Age and gender must be considered while interpreting lymphocytopenia in COVID-19 patients. BC Cytomics FC 500 is checked weekly with repeated setup according to the manufacturer's instructions.
