Spear Bio said Monday it has developed a tool to help researchers understand patients’ COVID-19 immune responses, and validate vaccines and therapeutics being developed for the disease.

The firm said its NAB-Sure SARS-CoV-2 test kit uses RT-PCR to simplify testing for SARS-CoV-2 neutralizing antibodies (NAbs) and provides qualitative and quantitative NAb titer measurements.

The testing approach and assay performance means the assay can work with diverse types of biospecimens and sample sizes, the firm said, including serum, plasma, and microsamples such as dried blood spots.

Available for sale in the U.S. for research use only, the test was developed by former Harvard University scientists based at the Wyss Institute for Biologically Inspired Engineering.
