LYMPHOCYTE SUBSET ENUMERATION (TBNK) FOR COVID SEVERITY ASSESSMENT

THIS TEST IS DESIGNED FOR ENUMERATING THE PERCENTAGE AND ABSOLUTE COUNTS OF LYMPHOCYTE SUBSETS (TBNK). IN CONFIRMED COVID 19 PATIENTS CD3+CD4+ AND/OR CD3+CD8+ LYMPHOCYTE COUNTS CAN BE USED AS AN AID IN DETERMINING THE ELEVATED RISK OF INTUBATION WITH MECHANICAL VENTILATION, AND THE RISK OF MORTALITY IN CONJUNCTION WITH CLINICAL FINDINGS AND THE RESULTS OF OTHER LABORATORY TESTS. CD4 AND CD8 T-CELLS ARE IMPORTANT FOR TRIGGERING THE ANTIBODY RESPONSE AND VIRAL KILLING RESPECTIVELY. SEVERAL PUBLISHED STUDIES HAVE SHOWN THAT INDIVIDUALS WITH COVID 19 TYPICALLY EXHIBIT A DECREASE OF CD4 AND/OR CD8 COUNTS WITH INCREASING DISEASE SEVERITY.
