Patent number: 8154713Abstract: New diagnostic parameters or indexes for detection of absolute iron deficiency, latent iron deficiency, functional iron deficiency, or latent functional iron deficiency have been disclosed. The parameters include a RBC size factor, RSf1 defined by the formula of (MCV×MRV)1/2, or RSf2 defined by the formula of (MCV×MRV)/100, a volume-hemoglobin factor (VHf) defined by the formula of (MCV×Hgb)/100, and a volume-hemoglobin/distribution factor (VHDWf) defined by the formula of (MCV×Hgb)/(RDW×10). Further disclosed are the methods of using these parameters for detection of absolute iron deficiency, latent iron deficiency, functional iron deficiency, or latent functional iron deficiency. Also disclosed is a method of using RSf for detection of hemochromatosis.Type: GrantFiled: August 31, 2009Date of Patent: April 10, 2012Assignee: Beckman Coulter, Inc.Inventor: Ramon Simon-Lopez

Patent number: 7586589Abstract: Methods for determining the responsiveness of a patient to recombinant human erythropoietin therapy are disclosed. In one approach, the method includes obtaining a volume-Hgb factor (VHf) defined as a product function of MCV and Hgb from a patient's blood sample; comparing VHf to a predetermined criterion; and reporting indication of responder if VHf meets the predetermined criterion. The method further includes using a RBC size-hemoglobin factor (RSHf) defined as a product function of MCV, MRV and Hgb, or using a function of VHf and RDW for determining the responsiveness. In another approach, the method includes using a RBC size factor (RSf) defined as a product function of MCV and MRV, in combination with transferrin saturation (TSAT) for determining the responsiveness to the erythropoietin therapy.Type: GrantFiled: September 21, 2006Date of Patent: September 8, 2009Assignee: Beckman Coulter, Inc.Inventor: Ramon Simon-Lopez

Patent number: 7361510Abstract: New diagnostic indexes and the method of use for detection of iron deficiency have been disclosed. These include a logistic function of mean cell hemoglobin (MCH) and mean cell volume (MCV), and a logistic function of mean cell hemoglobin concentration (MCHC) and MCH.Type: GrantFiled: January 19, 2007Date of Patent: April 22, 2008Assignee: Beckman Coulter, Inc.Inventors: Robert T. Magari, Ramon Simon-Lopez

Patent number: 7361512Abstract: A method of producing low hemoglobin concentration cell percentage (LHCC %) and the method of use for detection of iron deficiency have been disclosed. LHCC % is a sigmoid function of mean cell hemoglobin concentration (MCHC), which correlates linearly with hypochromic red cell percentage.Type: GrantFiled: January 19, 2007Date of Patent: April 22, 2008Assignee: Beckman Coulter, Inc.Inventors: Cheng Qian, Ziling Huo, Ramon Simon-Lopez

Patent number: 7256048Abstract: A method of detecting parasite infection, particularly malaria, includes mixing a blood sample with a lytic reagent system to lyse red blood cells, and to form a sample mixture; performing a differential analysis of white blood cells of the sample mixture on a blood analyzer, and obtaining a cell volume distribution of a white blood cell subpopulation from a cell volume measurement used in the differential analysis; obtaining a cell volume parameter from the cell volume distribution of the white blood cell subpopulation; evaluating the cell volume parameter against a predetermined criterion, and reporting an indication of the parasite infection if the cell volume parameter meets the predetermined criterion. The method also uses a discriminant obtained from cell volume parameters of two different white blood cell subpopulations against a predetermined criterion. The method further use a cell distribution parameter of a cell distribution obtained using a RF impedance measurement.Type: GrantFiled: February 18, 2005Date of Patent: August 14, 2007Assignee: Beckman Coulter, Inc.Inventor: Ramon Simon-Lopez
