A method for determining SARS-CoV-2 coronavirus from a sample, the method comprising a) providing i. a solution (201, 301) comprising ∘ one or more components (202, 302) adapted to neutralize the coronavirus, ∘ one of more components (203, 303) adapted to expose glycoproteins of the coronavirus, ii. a conjugate (204, 304, 404) comprising ∘ a first lectin (206, 306, 406) adapted to bind the glycoproteins, wherein the binding is selective, ∘ a signal generation means (207, 307, 407), and iii. a probe (205, 305, 405) comprising a detection zone (205b, 305b, 405b) comprising an immobilized second lectin (209, 309, 409) adapted to bind the glycoproteins, wherein the binding is selective, b) immersing the sample to the solution, c) exposing the conjugate to the solution comprising the sample, d) exposing the detection zone to the solution comprising the sample and the conjugate, e) preferably removing unbound material from the detection zone, f) detecting signal derived from the signal generation means on the detection zone, and g) determining the SARS-CoV-2 coronavirus in the sample based on the detecting, characterized in that the first lectin and the second lectin is selected from O-glycan binding lectins. a) providing i. a solution (201, 301) comprising ∘ one or more components (202, 302) adapted to neutralize the coronavirus, ∘ one of more components (203, 303) adapted to expose glycoproteins of the coronavirus, ii. a conjugate (204, 304, 404) comprising ∘ a first lectin (206, 306, 406) adapted to bind the glycoproteins, wherein the binding is selective, ∘ a signal generation means (207, 307, 407), and iii. a probe (205, 305, 405) comprising a detection zone (205b, 305b, 405b) comprising an immobilized second lectin (209, 309, 409) adapted to bind the glycoproteins, wherein the binding is selective, i. a solution (201, 301) comprising ∘ one or more components (202, 302) adapted to neutralize the coronavirus, ∘ one of more components (203, 303) adapted to expose glycoproteins of the coronavirus, ∘ one or more components (202, 302) adapted to neutralize the coronavirus, ∘ one of more components (203, 303) adapted to expose glycoproteins of the coronavirus, ii. a conjugate (204, 304, 404) comprising ∘ a first lectin (206, 306, 406) adapted to bind the glycoproteins, wherein the binding is selective, ∘ a signal generation means (207, 307, 407), and ∘ a first lectin (206, 306, 406) adapted to bind the glycoproteins, wherein the binding is selective, ∘ a signal generation means (207, 307, 407), and iii. a probe (205, 305, 405) comprising a detection zone (205b, 305b, 405b) comprising an immobilized second lectin (209, 309, 409) adapted to bind the glycoproteins, wherein the binding is selective, b) immersing the sample to the solution, c) exposing the conjugate to the solution comprising the sample, d) exposing the detection zone to the solution comprising the sample and the conjugate, e) preferably removing unbound material from the detection zone, f) detecting signal derived from the signal generation means on the detection zone, and g) determining the SARS-CoV-2 coronavirus in the sample based on the detecting, characterized in that the first lectin and the second lectin is selected from O-glycan binding lectins.
