| abstract |
The invention discloses a combined detection reagent strip for BNP, NT-proBNP and sST2 and a preparation method, comprising a sample pad, a binding pad, an analysis membrane, an absorption pad and a bottom plate; the bottom plate is sequentially provided with a sample pad, a binding pad and an analytical membrane , absorption pad; the binding pad is partially overlapped on one side of the analytical membrane; the absorption pad is partially overlapped on the other side of the analytical membrane; the sample pad is partially overlapped on the binding pad; the analytical membrane is provided with three detection lines and a quality control Line; binding pads are coated with BNP antibody label, NT-proBNP antibody label, sST2 antibody label. This case can be tested jointly, one sample, one sample addition, one test, and the test results of BNP, NT‑proBNP, and sST2 can be obtained at the same time, which simplifies the operation steps, reduces the amount of samples, and saves time and cost; there are many types of samples that can be tested. , including serum, plasma, whole blood and peripheral blood samples, and does not need to pre-process the samples, the operation is simple, convenient and fast. |
