  • Patent number: 7473558
    Abstract: The present invention teaches a marker useful for detection and measurement of free radical damage. Specifically, the invention takes advantage of alterations which occur to the N-terminus of the albumin molecule, a circulating protein in human blood, in the presence of free radicals. These alterations affect the ability of the N-terminus of the albumin molecule to bind metals. Methods for detecting and quantifying this alteration include evaluating and quantifying the cobalt binding capacity of an albumin containing sample, analysis and measurement of the ability of albumin to bind exogenous cobalt, detection and measurement of the presence of copper in a purified albumin sample and use of an immunological assay specific to the altered form of serum albumin which occurs following free radical damage.

  • Publication number: 20060191788
    Abstract: The subject invention comprises electrochemical methods and devices for in vitro detection of an ischemic event in a patient sample. Following addition of a known amount of a transition metal ion to the patient sample, electrodes are used to measure the current or potential difference of non-sequestered transition metal ion in the sample. The amount of non-sequestered transition metal ion in the sample reflects the degree of modification to albumin that is the result of an ischemic event.

  • Patent number: 7074194
    Abstract: The subject invention relates to the detection, diagnosis and risk stratification of clinical events such as acute coronary syndrome, in patients with signs and symptoms of suspected cardiac origin. In one embodiment, a clinical event in a patient is diagnosed by obtaining the patient's ECG, and at least one in vitro diagnostic assay, preferably an assay for a marker of ischemia, and optionally in vitro diagnostic assays for necrotic markers or other cardiac indicators, and combining the foregoing results in an algorithm to provide a diagnosis or a risk stratification of the clinical condition.
