Patent ID: 8027814

Claim:
A point-of-care method for assessing whether a condition in an individual is a hemorrhagic condition, comprising the steps of: (a) obtaining a cerebrospinal fluid sample comprising at least one analyte from an individual; (b) analyzing the cerebrospinal fluid sample by a spectrophotometer which scans an entire spectral wavelength range of from about 350 nm to about 650 nm and determines absorption data of at least one analyte in the sample over the entire spectral wavelength range; (c) determining a concentration of at least one analyte in the sample by applying a mathematical algorithm to the absorption data over the entire spectral wavelength range of step (b); and (d) assessing at the point-of-care of the individual whether the condition of the individual is a hemorrhagic condition based on the concentration of at least one analyte determined in step (c), wherein the concentration of at least one analyte in the sample may be determined in the presence of one or more additional proteins in the sample.
