Abstract: A method of determining whether a subject is likely to have a condition includes measuring concentration levels of a plurality of target biomarkers in a sample obtained from the subject; comparing the measured concentration levels to respective reference concentration levels; in the event that the measured concentration level of at least one of the target biomarkers is less than its respective reference concentration level, and the measured concentration level of at least one of the target biomarkers is greater than its respective reference concentration level, providing an indication that the subject is likely to have the condition, and otherwise: providing an indication that the subject is unlikely to have the condition.

Abstract: An apparatus and method for rapidly and accurately identifying and quantifying analytes in a complex mixture is disclosed. The apparatus comprises an ultra-sensitive cavity-enhanced spectrometer coupled to data-collection and analysis devices. The method comprises the use of a database containing the absorption cross-sections of various analytes to numerically determine the composition of the sample.
