Test strip for testing analyte in sample

Abstract

The invention discloses a test strip for testing an analyte in a liquid sample. The test strip includes a first support sheet, where a sample pad, a label pad and a test pad are sequentially arranged on a front face of the first support sheet from upstream to downstream; the label pad includes a label that is capable of flowing with a liquid; the test pad includes a fixed binding substance that is incapable of flowing with the liquid; and a layer of hydrophobic medium is coated on a back face of the first support sheet, to prevent the liquid sample from flowing from the back face of the first support sheet and wetting the test pad or the label pad in a downstream area in advance when the sample pad contacts the liquid sample.
