Claim 0:
1. A blood analysis method, comprising the following steps:
providing a blood sample;
mixing a first aliquot of the blood sample with a diluent agent to prepare a first test sample;
mixing a second aliquot of the blood sample with a lytic reagent to prepare a second test sample, wherein red blood cells in the second test sample are lysed by the lytic reagent;
detecting electrical impedance signals of the first test sample;
detecting at least two types of optical signals of the second test sample;
acquiring first volume distribution data of the first test sample based on the electrical impedance signals;
generating a scattergram of the second test sample based on the at least two types of optical signals; identifying a non-white blood cell region in the scattergram based on the at least two types of optical signals; and acquiring second volume distribution data of the second test sample based on the non-white blood cell region;
acquiring red blood cell detection data of the blood sample;
determining whether the blood sample may contain schistocytes based on the first volume distribution data, the second volume distribution data and the red blood cell detection data; and
providing an alarm for indicating that the blood sample may be a sample containing schistocytes if the blood sample is determined to contain schistocytes.
