Introduction

Fred L Larsen is a notable inventor based in Miami Lakes, Florida, recognized for his contributions to the field of blood analysis. With two patents to his name, Larsen has developed innovative reagents that enhance the accuracy and efficiency of blood cell counting and hemoglobin determination.

Latest Patents

Larsen's latest patents include a reagent for combined diluting and lysing whole blood. This improved reagent allows for the simultaneous diluting and lysing of whole blood, which is essential for instruments that perform electronic blood cell counting and hemoglobin determination. The reagent effectively prevents platelet aggregation, thereby improving the accuracy of the white blood cell count. Another significant patent is for a multi-purpose blood diluent and lysing agent for differential determination of various leukocyte populations. This method and reagent system is designed for use with automatic blood cell analyzers. The blood diluent is an osmotically balanced aqueous solution that maintains erythrocyte morphology and provides stabilizing, buffering, and bacteriostatic actions. The stromatolyzing reagent consists of a mixture of quaternary ammonium salts, a chromagen forming agent, and a non-cationic surfactant additive. This combination not only positions lymphoid and myeloid populations accurately but also minimizes protein deposits in the analyzer's sensing orifices.
