Abstract

The invention discloses a C-reactive protein detection method and system and a storage medium, and aims to obtain an alternating current signal through a cuvette by adopting an alternating current signal as an excitation source instead of a direct current signal, so that the anti-interference performance is high, the interference of an external signal is avoided, and the detection accuracy is improved. And after the alternating current signal is amplified, low-frequency drift can be effectively filtered through the narrow-band filter, so that the temperature drift influence of the operational amplifier is reduced, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a detection method, system and storage medium of C-reactive protein. Background technique [0002] C-reactive protein is a non-specific inflammatory marker, directly involved in inflammation and cardiovascular diseases such as atherosclerosis, and is the most powerful predictor and risk factor for cardiovascular diseases. [0003] At present, the measurement of C-reactive protein is mainly through scattering method and transmission method or a combination of both, but the LED or laser excitation source is a DC power supply, so the generated excitation light source and the signal received by the sensor are all DC signals. The C-reactive protein sensor is usually installed in the optical system and needs to be transmitted to the circuit board for processing. Due to the poor anti-interference ability of the DC signal, this transmission is easily interfered by external...
