Problems solved by technology

The disadvantages are: (1) It can only detect samples qualitatively, it is difficult to realize quantitative detection of samples, and it is even more difficult to realize rapid quantitative detection of multi-component samples
(2) For some samples with extremely low antigen or antibody content, it is difficult to judge the results with the naked eye, and the detection sensitivity is low
RFID tags are small in size, large in information storage capacity, and require no manual intervention for identification. They are also an ideal means of information access and identification, but few people use them in the field of biomedical testing.

Abstract

Belonging to the in vitro diagnosis field, the invention in particularly relates to a test strip card with a storage medium (11) for storing a detected object standard curve or coefficient parameter and other information for the detection. The test strip card includes a card box (3) and a test strip (2) inside. The storage medium (11) is mounted on the card box (3). During sample detection, the characteristic signal of a detection band (6) in the test strip (2) is collected by an instrument with a signal detection function, and by combining the instrument, the detected object standard curve or coefficient parameter are read at the same time from the storage medium (11), so that a sample single-component or multicomponent concentration can be calculated. The test strip card for sample detection provided by the invention has the characteristics of simplicity, rapidity, high sensitivity, subjective result, and flexible application, etc.

Description

technical field [0001] The present invention belongs to the field of in vitro diagnosis, and specifically relates to an instrument with a storage medium 11 for storing the detection information such as the standard curve or coefficient parameters of the tested object, combined with a signal detection function, which can quickly detect a single component or multiple groups of samples. Score test strip card. 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. The disadvantages are: (1) It can only detect samples qualitatively, but it is difficult to realize quantitative detection of samples, and it is even more difficult to realize rapid quantitative detection of multi-component samples. (2) For some samples with extremely low antigen or antibody content, it is difficult to judge the ...
