Patent number: 7613488Abstract: The present invention provides a method for measuring a blood analyte concentration of a body part comprising removing a portion or all of the blood from the body part to produce a modified body part, and recording a first absorbance value of the modified body part. This is followed by filling the body part with blood to produce a filled body part, and recording a second absorbance value of the filled body part. A difference spectrum is obtained by subtracting the first absorbance values from the second absorbance values, and a calibration algorithm for the blood analyte is applied to the difference spectrum, thereby measuring the concentration of the blood analyte. Also provided is an apparatus for determining the concentration of a blood analyte of a body part. The apparatus comprising a chamber of a size and shape to receive the body part, where the chamber comprises an element for withdrawing and reintroducing blood from the body part, when the body part is inserted within the chamber.Type: GrantFiled: December 22, 2003Date of Patent: November 3, 2009Assignee: NIResults Inc.Inventors: George N. Maracas, Romuald Pawluczyk, Duncan MacIntyre, Bronislaw Bednarz, Darin L. Farrelly, Chris Sterne, Ash Kaushal, Mang Li, Kenneth Anthony Morand

Patent number: 7343185Abstract: The present invention provides a method for identifying a concentration of a compound within a part of a subject. The method involves measuring the amount of electromagnetic radiation reflected by, or transmitted through the part with a detector, and using a quantitative mathematical analysis to determine the concentration of the compound in one, or more than one compartment, including a blood, interstitial, cellular, lymph, or bone compartment, of the part. A corrected concentration of the compound may be then determined within a compartment of interest, or a total concentration of the compound may be accurately determined. Preferably, the compound is glucose. From this determination, a clinical condition in a human or animal may be made by correlating the concentration of a measured compound in the compartment of a part of the human or animal to a clinical condition in need of treatment.Type: GrantFiled: June 18, 2003Date of Patent: March 11, 2008Assignee: NIR Diagnostics Inc.Inventors: James Samsoondar, Duncan MacIntyre

Patent number: 7328052Abstract: The present invention provides an apparatus and a method for identifying the risk of a clinical condition in a human or animal by correlating Near Infrared (NIR) absorbance spectral data with one or several parameters including a concentration of one or more substances in the skin, a concentration of one or more substances in skin plus subdermal tissue, a score derived from one or more clinical tests like a stress test on a treadmill, coronary angiography, or intravascular coronary ultrasound. The method determines the concentration of a compound in the skin of a human or animal and comprises the steps of placing a part of the skin against a receptor, directing electromagnetic radiation (EMR) from the near-infrared spectrum onto the skin, measuring a quantity of EMR reflected by, or transmitted through, the skin with a detector; and performing a quantitative mathematical analysis of the quantity of EMR to determine the concentration of the compound, for example free and esterfied cholesterol.Type: GrantFiled: September 17, 2004Date of Patent: February 5, 2008Assignee: NIR Diagnostics Inc.Inventors: James Samsoondar, Duncan MacIntyre, Ashwani Kaushal

Patent number: 7198955Abstract: A method is disclosed whereby the concentration of a blood substitute, such as cross-linked hemoglobin, in a serum or plasma specimen is rapidly and accurately identified and quantified. The method further takes the measured concentration of the blood substitute and uses it to correct for its effect, if any, on a measured analyte concentration, e.g., serum/plasma total protein. Further, the method allows for the determination of the concentration of true hemoglobin in the presence of blood substitutes. The method is carried out in respect of samples contained in a primary or secondary labelled tube, or a pipette tip used to dispense serum or plasma in a blood analyzer.Type: GrantFiled: October 16, 1997Date of Patent: April 3, 2007Assignee: NIR Diagnostics Inc.Inventors: James Samsoondar, Duncan MacIntyre
