BD COVID-19 immune assessment assay available in Europe


Data from the first global wave of COVID-19 have shown that patients typically exhibit a remarkable decrease of CD4 and/or CD8 lymphocyte counts with increasing disease severity

BD today announced the CE mark and European availability of a product for assessing immune function in COVID-19 patients.

The BD Multitest 6-Color TBNK Reagent with BD Trucount Tubes has been CE marked with expanded clinical application for the identification and enumeration of T-cell subtypes in COVID-19 patients.

Accurate counts of T-cell subsets may be critical in informing the clinical course of action because T-cells are essential for viral killing and antibody response. The BD Multitest 6-Color TBNK Reagent with BD Trucount Tubes enables clinicians to go beyond the complete blood count (CBC) to better understand the underlying mechanisms for severity in COVID-19 patients, especially those with co-morbidities.

This test has been used for more than a decade to assess immune function in HIV patients and BD says it may now also help clinicians better understand COVID-19 patient immune response, and when used in conjunction with clinical findings and laboratory testing, inform patient treatment plans.

“The availability of this product with the expanded clinical application in COVID-19 patients is an important step in helping clinicians better understand how patient immune systems are responding to COVID-19 infection,” said Puneet Sarin, worldwide president, Biosciences at BD, “BD is a trusted partner in immunology research and clinical care with a long history helping clinicians and patients better understand immune function to make patient care decisions. Bringing this expertise to clinicians treating COVID-19 patients presents a great opportunity to enable deeper immune assessment of patients, which could lead to improved uses of precious resources within a hospital while helping get patients on the right clinical path.”

The BD Multitest 6-Color TBNK Reagent with BD Trucount Tubes is used in conjunction with the BD FACSLyric and BD FACSCanto II Clinical Flow Cytometers and the BD FACSLyric/BD FACSDuet Sample-to-Answer Solution, which enables automated processing of samples, removing any unnecessary exposure to lab personnel.
