[0003] However, when using chemiluminescent analysis methods such as analyzing sample types, the photometric module that obtains the light transmission of the tip will have a certain degree of light decay during use. For example, the aging of hardware or optical modules will cause each channel to measure the corresponding The amount of light transmitted by the tip fluctuates or is unstable, which will lead to misjudgment of the sample type and affect the sample detection

Embodiment Construction
[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0036] Such as figure 1 As shown, a kind of chemiluminescent detection method provided by the present invention comprises the following steps:
[0037] S101. Obtain a reference light transmittance;
[0038] Specifically, the reference light transmittance is the light transmittance when the suction head (tip head) is placed in the initial state of the instrument and no tip is placed. The reference light transmittance can be preset and stored before the analyzer leaves the factory. The preset reference light transmittance is automatically obtained at the first startup, and the reference light trans...

Abstract
The invention discloses a chemiluminescence detection method for judging the type of a sample sucked by a syringe fitted with a suction head (tip). The chemiluminescence detection method comprises: acquiring reference light penetration; fitting the tip to a tip holding position, moving the tip to a suction position, sucking a sample, and acquiring suction light penetration of the tip that alreadysucks the sample; calculating a ratio of the suction light penetration to the stored reference light penetration, and judging the type of the sample according to the ratio. The chemiluminescence detection method performs ratio calculating to judge sample types and may adapt to attenuation of components of the analyzer, so that the requirement on hardware boards is lowered, and instability of detection results to light transmittances of various channels due to self-aging, difference, loading and other factors of photoelectric modules, such as LED light sources or photoelectric receivers. The invention also provides a chemiluminescence detection device having the same technical effects, a chemiluminescence immunoassay analyzer and a readable storage medium.
Description
technical field [0001] The invention relates to the technical field of in vitro diagnosis, in particular to a chemiluminescence detection method and device, a chemiluminescence immunoassay analyzer, and a storage medium. Background technique [0002] When in vitro diagnostic equipment such as chemiluminescent immunoassay analyzers measure specific components in blood samples, it is necessary to determine the type of the sample to be tested, such as whole blood or serum, and then perform corresponding detection according to the determined blood sample type. The existing blood sample type judgment Methods The light transmittance when the tip sucks different samples, such as whole blood or serum, is used as the judgment index. [0003] However, when using chemiluminescence analysis methods such as analyzing sample types, the photometric module that obtains the light transmission of the tip will have a certain degree of light decay during use. For example, the aging of hardware ...
