Abstract

A blood detection method is provided, including: treating a blood sample with a first reagent to obtain a test sample, wherein the first reagent includes a hemolytic agent for lysing red blood cells in the blood sample into fragments having light scattering characteristics significantly different from those of platelets; passing particles in the test sample through a detection area of an optical detection system one by one, to obtain optical information of the test sample; and obtaining optical information of platelets according to at least two types of the optical information of the test sample. In the method, a platelet count is obtained by lysing red blood cells in a blood sample, and white blood cell subpopulations can be also differentiated.
