Portable biochemical immunity analyzer and testing method

The invention discloses a portable biochemical immunity analyzer and a testing method.The analyzer comprises a first shell and a second shell, a containing cavity is formed between the first shell and the second shell, and a reagent card, a moving assembly and an optical detection module are arranged in the containing cavity; and the moving assembly drives the optical detection module to move above the reagent card so as to scan and detect the reagent card. The optical detection module comprises a first light source, a light receiver and a second light source, the first light source and the second light source are obliquely arranged on the two sides of the light receiver and are symmetrically arranged relative to the light receiver, the reagent card is located under the light receiver, and an optical filter and a lens are arranged between the light receiver and the reagent card. According to the reagent card, a product based on a fluorescence immunochromatography technology and a product based on a reflection
