The BIOSYNEX COVID-19Ag BSS test is a qualitative membrane based immunoassay that uses highly sensitive monoclonal antibodies to detect the nucleocapsid protein of SARS-CoV-2 in nasopharyngeal (NP) swab.The test strip contains colloidal-gold conjugated particles with monoclonal antibodies against the nucleocapsid protein of SARS-CoV-2. The secondary antibodies for nucleocapsid protein of SARS-CoV-2 are coated on the membrane. When the sample is added to the sample well,the conjugates dried in the reagent pad are dissolved and migrate along withthe sample.
If SARS-CoV-2 antigen is present in the sample, a complex formed between the anti-SARS-CoV-2 conjugate and the virus will be captured by the specific anti-SARS-CoV-2 monoclonal antibodies coated on the test line region (T). Absence of the T line suggests a negative result.An internal procedural control is included in the assay, in the form of a colored line appearing in the Control (C)area, indicating that the proper volume of sample has been added and membrane wicking has occurred.
