Patent ID: 7361512

Claim:
A method of producing a low hemoglobin concentration cell percentage (LHCC %) of a blood sample on a hematology analyzer comprising: (a) mixing a first aliquot of a blood sample with a blood diluent to form a first sample mixture, analyzing said first sample mixture on said hematology analyzer, and obtaining a mean cell volume of red blood cells (MCV) and a red blood cell concentration (RBC); (b) mixing a second aliquot of said blood sample with a reagent system to form a second sample mixture, analyzing said second sample mixture on said hematology analyzer, and obtaining a hemoglobin concentration (Hgb) of said blood sample; (c) obtaining mean cell hemoglobin concentration (MCHC) using said MCV, said RBC and said Hgb; (d) obtaining said low hemoglobin concentration cell percentage (LHCC %) defined as a function of said MCHC obtained by non-linear rescaling of said MCHC; and (e) reporting said LHCC % of said blood sample on said hematology analyzer.
