20180067135 · 2018-03-08 ·

This invention relates to the measurement of hemoglobin in the blood. Previously, chemical interference from medications, other blood components, and incomplete reagent rehydration can impact the accuracy and prolong the reaction time required to determine total hemoglobin in blood. Embodiments of the present invention use a disposable body is housed within the capillary channel and adapted to receive a flow of blood from the entrance such that air in the disposable body is pushed out through a vent. A measurement system is configured to measure a property of the flow of blood. That property can be correlated to total hemoglobin count.

Systems and methods for electrochemical point-of-care detection of hemoglobin

A method includes lysing the red blood cells of a whole blood sample, oxidizing the free hemoglobin in the lysed sample, and cleaving FVH from the hemoglobin A1C to form an electrochemical test solution. A first portion of the electrochemical test solution is reacted with fructosyl peptide oxidase and a reduced ruthenium mediator to form a first reaction product. A first electrical property of the first reaction product is measured, the measurement being indicative of hemoglobin A1C in the blood sample. A second portion of the electrochemical test solution is reacted with ferrocyanide to form a second reaction product. A second electrical property of the second reaction product is measured, the measurement being indicative of total hemoglobin in the blood sample. Hemoglobin A1C, total hemoglobin, and % HbA1C are determined based on the first and second electrical properties. Also provided are systems and components useful in performing the disclosed methods.

Electrochemical test sensors and analysis methods are described that reduce or eliminate the pre-treatment or dilution of blood samples prior to HbA1c analysis. Thus, a blood sample obtained from a blood draw or phlebotomy may be introduced to the electrochemical test sensor for HbA1c analysis. The described test sensors immobilize or deactivate incompatible reagents, enzymes, and antibodies so they do not substantially interfere with each other during the analysis. The test sensors also use heat to catalyze reactions that otherwise would proceed at too slow of a rate to be practical.

Method for Stabilizing Hemoglobin and Reagents for Performing the Same

A stool resuspension solution comprising a hemoglobin stabilization reagent is provided. In some embodiments, the hemoglobin stabilization reagent may be an osmolyte, a polyvalent cation, a sugar or polysaccharide and, optionally, a polyvalent cation, a protoporphyrin, or an HRP stabilization component and, optionally, a polyvalent cation. A method of stabilizing hemoglobin in a stool sample in the solution is also provided, as well as a sample collection device containing the solution.

Blood analysis method, control device and blood cell analyzer

The present disclosure provided a blood cell analyzer, a control device and a blood analysis method thereof. In the method, a first reagent is mixed with a sample to obtain a first testing sample, and then a second reagent is mixed with the first testing sample for a further reaction to get a second testing sample for basophil classification and/or HGB measurement. A blood sample may be tested in one reaction cell through time-division multiplexing technology to obtain four groups leukocytes classification result and HGB result by single detection channel. Thus, the structure of the analyzer may be greatly simplified on the premise of guaranteeing the performance of the analyzer, the size and cost of the analyzer may reduce and a performance-price ratio of the analyzer may increase.

ROTATABLE FLUID SAMPLE COLLECTION DEVICE
