Problems solved by technology

[0003] However, existing in vitro diagnostic equipment is often only suitable for one diagnostic technology and a corresponding specific optical detection technology, that is, the system used for biochemical detection cannot be used for immunological detection or nucleic acid detection, and vice versa

Moreover, taking immunoassays as an example, immunoassay devices based on absorbance detection generally cannot do chemiluminescence detection or imaging detection of lateral flow immunoassay strips, and vice versa
