Hemoglobin concentration detection method and blood cell analyzer

Abstract

The invention provides a hemoglobin concentration detection method and a blood cell analyzer. The hemoglobin concentration detection method comprises the following steps: detecting a first detection sample injected into a reaction tank and obtaining a first HGB value, wherein the first detection sample comprises a diluent, a blood sample and a first hemolytic agent; detecting a second detection sample injected into the reaction tank and obtaining a second HGB value, wherein the second detection sample is obtained by adding a second hemolytic agent into the first detection sample of the reaction tank and uniformly mixing; and selecting the minimum value of the first HGB value and the second HGB value as the HGB value of the blood sample. As the detection result of the HGB value is too high if the influence of bubbles exists in the detection process, the minimum value is selected from the first HGB value and the second HGB value as the HGB value of the blood sample so that the influence of the bubbles on the detection result of the HGB value can be reduced as much as possible, and the accuracy of the HGB detection result is improved.

Description

technical field [0001] The application relates to the technical field of blood detection, in particular to a detection method of hemoglobin concentration and a blood cell analyzer. Background technique [0002] The blood cell analyzer can be used to detect the concentration of hemoglobin (HGB), and the HGB value is an important parameter for anemia diagnosis. [0003] At present, the main process for HGB value detection is: add diluent, blood sample and hemolyzing agent to the reaction cell, irradiate the reaction cell with a light source, use the detected voltage value as the sample voltage, add diluent to the reaction cell, and irradiate the reaction with the light source. pooling, using the detected voltage value as the background voltage, and then calculating the HGB value of the blood sample based on the sample voltage and the background voltage. [0004] At present, it is unavoidable in the detection process that there may be air bubbles in the reaction cell. If there...

AI Technical Summary

Problems solved by technology

[0004] At present, it is unavoidable in the detection process that there may be air bubbles in the reaction cell. If there are air bubbles in the reaction cell, the reaction cell containing the test sample is irradiated with a light source, which will cause the detected sample voltage to be low, which will lead to HGB value. The test result is high, which affects the doctor's diagnosis of the disease
