The invention relates to the technical field of biomedical detection, in particular to a
rapid detection method for a specific biomarker of
precocious puberty of central girls. When a blood sample is detected, an original
light intensity sequence of the chromatographic test strip is obtained and adjusted into a standardized net
signal sequence; the
color band width is controlled by the
chromatography flow velocity and can reflect the fluid
diffusion level under the
sample viscosity, so that the
quality control line reference width and the waveform sharpness are determined, and the waveform distribution characteristics are grasped; if the
blood viscosity is increased, the
light intensity of
quality control and interference capture intervals is distorted, and when the
light intensity of the interference capture intervals meets preset conditions, saturation evaluation indexes are determined according to peak shape characteristics and
quality control line related parameters of the interference capture intervals, and the saturation degree is evaluated; analyzing the light intensity in a membrane gap interval to obtain a background trailing ratio, and quantifying the leakage flux of free interferents; finally, the saturation evaluation index and the background trailing ratio are fused to obtain a blood sample effective value, the
sample condition can be comprehensively and accurately reflected, and whether the sample is suitable for detection or not can be determined.
