Novel Coronavirus Testing

The invention proposes a testing device and method for detecting infection with or immunity to SARS-Cov-2 of a subject, the method comprising the following steps: (i) contacting a urine sample from the subject with an application area of a testing device comprising a urine sorption material defining a sequence of said application area, a conjugate area and a testing area, the areas being in direct or indirect capillary flow communication with each other, (ii) allowing the urine sample to flow by capillarity from said application area to said conjugate area, said conjugate area comprising a testing conjugate movably held therein, wherein said testing conjugate comprises or consists of a polypeptide having an amino acid sequence that shares sequence identity of at least 90%, preferably at least 95%, with a SARS-CoV-2 protein or fragment thereof, coupled to a first colored marker, (iii) allowing the urine sample to continue to flow by capillarity to the testing area, said testing area comprising a testing sub-area with immobilized anti-human IgA antibodies, and (iv) determining infection with or immunity SARS-CoV-2 of the subject by visually inspecting the testing sub-area of the testing area for a color build-up, wherein the presence of a color build-up is indicative of said infection with or immunity to SARS-CoV-2.
