LATERAL FLOW IMMUNOASSAY DEVICE

摘要

Provided is a lateral flow immunoassay device for quantitatively or qualitatively measuring target analytes in whole blood samples. The device comprises, in sequence in the lateral direction: a sample receiving pad, a conjugate pad, a flow delaying pad and a wicking membrane. The sample receiving pad receives a whole blood sample and isolates erythrocytes (red blood cells) from the whole blood sample and thereby blocks the flow of the erythrocytes. In particular, when the mean pore size of the sample receiving pad, the conjugate pad and the flow delaying pad are respectively P1, P2 and P3, there is the relationship P1 > P2 > P3.
