ELISpot assay to immune phenotype patients

Tech ID: T-019522

Technology Description

A team of researchers, led by Richard Hotchkiss at Washington University in St. Louis, have developed a version of the ELISpot assay to determine if COVID-19 patients are in a hyper-inflammatory or immunosuppressed state. The results of this assay, which can be performed with whole blood, are used to inform a more successful treatment plan.

While some COVID-19 patients suffer from cytokine storm due to an overactive immune system, this team of researchers has recently shown that another subset of patients see unrestrained viral infection due to a failure of host immunity. Those two subsets require polar opposite supportive treatments, so physicians need an assay to rapidly determine the immune status of the patient.

Stage of Research

The inventors developed a version of the ELISpot capable of using diluted whole blood and validated it on a sample of 127 patients, including 27 hospitalized with COVID-19.
