Abstract: Disclosed are methods and systems for confirming the identification of samples processed by a high-throughput analytical technique. The method may include the steps of distributing a plurality of individual samples to individual predetermined positions of a multi-sample test unit and distributing an identifier material to at least one predetermined position of the multi-sample test unit. The method may also include determining the absence or presence of an analyte in the plurality of individual samples, and determining the absence or presence of the identifier material, wherein the presence of the identifier material at the predetermined position of the multi-sample test unit is used to confirm the identity of the plurality of individual samples positioned in the multi-sample test unit. Also disclosed are systems for performing the disclosed methods or any of the steps of the disclosed methods. The methods and systems may be applied to high-throughput LC-MS/MS or other analytical methods.

Abstract: Multiplex analysis methods for rapid analysis of the presence or amount of two or more biomolecules in a sample are disclosed. Systems implementing such methods are further disclosed.
