Publication number: 20150031058Abstract: Methods of the invention involve determining a patient's compliance with a cholesterol lowering therapy. In certain aspects, the invention provides methods that involve conducting a first assay to determine a cholesterol biomarker level in a first sample from a patient prior to the patient undergoing a cholesterol lowering therapy. The methods may also involve conducting a second assay to determine a cholesterol level in a second sample obtained from the patient after the patient has started undergoing a cholesterol lowering therapy. Additionally, the methods involve associating the cholesterol level and the cholesterol biomarker level in which the association allows for the determination of the patient's compliance with the cholesterol lowering therapy.Type: ApplicationFiled: July 24, 2013Publication date: January 29, 2015Applicant: BOSTON HEART DIAGNOSTICS CORPORATIONInventor: Ernst J.

Patent number: 8932865Abstract: A method that enables quantification of cholesterol in high-density lipoprotein 3 (HDL3) in a test sample without requiring a laborious operation is disclosed. The method for quantifying cholesterol in HDL3 having: Step 1 wherein a surfactant that reacts with lipoproteins other than high-density lipoprotein 3 is reacted with a test sample to transfer cholesterol to the outside of the reaction system; and Step 2 in which cholesterol remaining in the reaction system is quantified. The method enables specific quantification of HDL3 cholesterol in a test sample using an automatic analyzer without requirement of a laborious operation such as ultracentrifugation or pretreatment. Further, quantification of the HDL2 cholesterol level can also be carried out by subtracting the HDL3 cholesterol level from the total HDL cholesterol level obtained by a conventional method for quantifying the total HDL cholesterol in a test sample.Type: GrantFiled: July 22, 2011Date of Patent: January 13, 2015Assignee: Denka Seiken Co., Ltd.Inventors: Maiko Higuchi, Yasuki Itoh

Patent number: 8906638Abstract: A method for quantifying remnant-like lipoprotein cholesterol in a sample simply and accurately without requiring separation operations, and a kit therefor are disclosed. A method for quantifying cholesterol in a remnant-like lipoprotein in a sample containing different lipoproteins including the remnant-like lipoprotein comprises a step (1) of erasing cholesterol in lipoproteins other than the remnant-like lipoprotein; and a step (2) of quantifying cholesterol in the remaining remnant-like lipoprotein. The step (1) is carried out under an action of a cholesterol esterase having a molecular weight of more than 40 kDa and not having a subunit having a molecular weight of not more than 40 kDa; and the step (2) is carried out under an action of a cholesterol esterase having a molecular weight of not more than 40 kDa or a cholesterol esterase having a subunit having a molecular weight of not more than 40 kDa.Type: GrantFiled: November 9, 2011Date of Patent: December 9, 2014Assignee: Denka Seiken Co., Ltd.Inventor: Yuhko Hirao

Publication number: 20140329258Abstract: A test strip to assist in determining the concentration of an analyte in a fluid sample comprises a base, at least one tab and a break line. The base includes a capillary channel and a test element. The capillary channel is in fluid communication with the test element. The test element is adapted to receive the fluid sample. The at least one tab is removably attached to the base. The capillary channel extends from the base into a portion of the tab. The break line intersects the capillary channel in which an inlet to the capillary channel is exposed along the break line when the tab is separated from the base.Type: ApplicationFiled: July 15, 2014Publication date: November 6, 2014Inventor: Roger Fleming
