Problems solved by technology

②The color of red blood cells (red) is similar or the same as the color displayed by colloidal gold (light red or purple), which will interfere with the judgment of test results
③Red blood cells interfere with many diagnostic assays, such as: in the detection of analytes, red blood cells may inhibit the binding between paired components of specific structures; red blood cells have enzyme activity, which may interfere with the generation of detection signals
Utility model patent No. ZL03217482.9 discloses a technical scheme of adding a red blood cell filter membrane between the colloidal gold conjugate of the colloidal gold test strip and the nitrocellulose membrane in an attempt to overcome the above-mentioned interference of red blood cells. The disadvantage is that : This technical measure does not begin to overcome from the "source" component (sample pad 4) of the test strip, but introduces the red blood cell filter membrane b

Abstract

The invention belongs to the field of in-vitro diagnosis, and particularly relates to a test strip card which can filter samples and is provided with a storage medium (14) for storing a tested object standard curve, coefficient parameters or other detection information. The test strip card comprises a card box (3) and a test strip (2) in the card box (3), wherein a storage medium (14) is installed on the card box (3). When detecting a sample, an instrument with signal detection function acquires characteristic signals of a test strip (2) detection belt (7) and calculates the sample single component or multicomponent concentration in combination with the tested object standard curve or coefficient parameters simultaneously read from the storage medium (14) by the instrument. The test strip card for detecting samples has is simple and quick, and has the characteristics of high sensitivity, objective result, high use flexibility and the like.

Description

technical field [0001] The invention belongs to the field of in vitro diagnosis, and specifically relates to an instrument that can filter samples by itself, has its own storage medium 14 to store the standard curve or coefficient parameters of the tested object, and can quickly detect a single sample in combination with an instrument with a signal detection function. Component or multi-component test strip cards. Background technique [0002] The immunochromatographic test strip technology mainly represented by colloidal gold test strips has been widely used in various aspects of immunoassay. The technique is simple and fast, with results within minutes. However, this technology has the following disadvantages: [0003] (1) Blood samples need to be separated from serum by equipment, and whole blood samples cannot be tested. Because: ① red blood cells in the whole blood sample will prevent the smooth migration of the reactant on the test strip. ②The color of red blood ce...
