ELISA for the detection of IgG antibodies to SARS-CoV-2 in human serum or plasma.

Indication of:

• Adaptive Immunity
• Recent or prior SARS-COV-2 infection
• Attenuation to reinfection

Suitable for serological surveillance studies

Independent validation by St. George’s University of London, UK and Liverpool School of Tropical Medicine, UK.

Large cohort of sequential samples.

Sensitivity data stratified by days post symptom onset and by days post lab confirmation (swab for RT-PCR)

The Symptomatic phase is representative for mild to moderate infections.

Sample volume: 5μL

Sample type: human venous serum / plasma and plasma from capillary whole blood (finger prick blood)

Use of 2 viral antigens for better sensitivity and specificity: NP (Nucleocapsid protein) and S2 (domain 2 spike protein)

Cross reactivity to other viruses and immunological conditions intensively tested
