Abstract: A method of assessing the analytical performance of a biochemical measured using a multi-analyte assay is described. The method includes analytically validating a measurement of the level of a first biochemical in a sample, wherein the first biochemical has been previously analytically validated for three or more analytical validation conditions; measuring the level of a second biochemical in a sample, wherein the second biochemical is structurally or biochemically related to the first biochemical; and comparing validation parameters of the first biochemical with validation parameters of the second biochemical to determine whether the performance of the second biochemical is acceptable based on the comparison results.

Abstract: A method of assessing the quality of a biological sample while maintaining the viability of the biological sample for intended use analysis is described herein. The method includes analyzing a biological sample obtained from a subject for an intended use, assessing the quality of the biological sample using one or more biomarkers of sample quality, and simultaneously performing intended use analysis on the same sample. Assessing the quality of the sample can include assessing compliance with sample handling protocols and assessing subject compliance.

Abstract: Methods and systems are described herein for small molecule biochemical profiling of an individual subject for diagnosis of a disease or disorder, facilitating diagnosis of a disease or disorder, and/or identifying an increased risk of developing a disease or disorder in the individual subject. Aberrant levels of small molecules present in a sample from an individual subject are identified and diagnostic information relevant to the individual subject is obtained based on the identified aberrant levels. The obtained diagnostic information includes one or more of an identification of at least one biochemical pathway associated with the identified subset of the small molecules having aberrant levels, an identification at least one disease or disorder associated with the identified subset of the small molecules having aberrant levels, and an identification of at least one recommended follow up test associated with the identified subset of the small molecules having aberrant levels.
