“Not everyone with COVID-19 infection has detectable antibodies in serology tests, and this may be a bigger problem in the majority who experience only mild or no symptoms. Also, it is not yet clear whether the presence of antibodies confers immunity,” Phill Keefe, senior vice president of product design, development, and delivery, Oxford Immunotec, said in the release. “T cell responses develop before antibody generation and can independently provide protection, so studying T cells could give us new insights into immunity to COVID-19.”
T-Spot technology uses a standardized sample prepared from peripheral blood, which standardizes cell numbers in the test to normalize for cell number variations between samples and allows the number of responding T cells to be enumerated for a more precise assessment of the T cell response.
