A new COVID-19 antibody assay can analyze up to 40,000 samples per day and is suitable for both serum and dried blood sampling.
The new COVID-19 antibody has been developed by LGC's Immunogenicity Centre of Excellence (Cambridge, UK) and uses serum or capillary blood collected remotely with the Mitra microsampling device from Neoteryx LLC (Torrance, CA, USA). Individuals can be tested for SARS-CoV-2 antibodies by visiting a blood draw center to provide a serum sample via phlebotomy, or by collecting their own blood sample at home using the Mitra device and a simple fingerstick method. The Mitra blood samples can be posted through the regular mail to LGC's Centre of Excellence laboratory for testing, where sample data are processed and reported using the company's custom LIMS system. The assay developed by LGC for SARS-CoV-2 antibody testing achieves specificity of (95% CI) 100% (98.7-100.0) and sensitivity of (95% CI) 98.0% (87.0-99.0) for samples taken 21 days post positive PCR test. Sample results can be reported within 24 hours of sample receipt.
"A real value of remote blood sampling with the Mitra device for testing in LGC's outstanding lab is that people don't have to leave home to learn if they have developed SARS-CoV-2 antibodies," said James Rudge, PhD, Technical Director, Neoteryx. "Our Mitra is designed with volumetric absorptive microsampling, or VAMS technology, which enables virtually anyone to collect a few drops of blood on the device with scientific precision."
"Our assay is suitable for partnering with employers for back to work testing using the self-sampling Mitra device, and therefore does not require a phlebotomist to take the blood sample in a healthcare setting," added LGC's Commercial Director, Michael van der Merwe. "The assay can also support patient stratification for clinical trials and COVID-19 vaccine development. As well as qualitative data, we can also provide semi-quantitative data on the level of antibodies present indicating the magnitude of the immune response."
