COVID-19 Patient Care
Now is the right time to help identify COVID-19 patients at elevated risks of Intubation with Mechanical Ventilation (IMV) and mortality.
BD Multitest™ 6-Color TBNK Reagent with BD Trucount™ Tubes is a trusted test now with clinically validated cut-off levels for specific lymphocyte T-cell subsets (CD4+ and/or CD8+) to help identify COVID-19 patients at hospital admission who are at increased risk of IMV and also increased risk of mortality, in conjunction with clinical findings and the results of other laboratory testing. Recognizing increased patient risk at admission can help inform the right course of action while prioritizing precious resources.
IMV-free probability for patients above and below CD4+ and CD8+ T-cell cut-offs
Scientific Resources
White Paper
Read about the validation of T-cell cutoffs values for CD4+ and CD8+ lymphocyte subsets in an Italian COVID-19 patient cohort. This study also showed that some commonly used laboratory tests such as total lymphocyte count, neutrophil-to-lymphocyte ratio, CRP, and ferritin lost significance in various analyses in comparison to CD4⁺ and CD8⁺ T-cell cutoffs.
Clinician Info-graphic
Feel more secure when managing COVID-19 patient risk. CD4+ and CD8+ T-cells are important in viral killing and antibody response and are often decreased in severe COVID-19. CD4+ and/ or CD8+ T-cell counts at hospitalization can aid in determining the risk of Intubation with Mechanical Ventilation (IMV) and risk of mortality, in conjunction with clinical findings and the results of other laboratory procedures. Relative risk is 5-6x higher for patients with T-cell subset counts below cut-off levels (CD4+ <250 cells/µl and/or CD8+ <100 cells/µl).
