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.

commonly used arylsulfatase extracted from the snail Helix pomatia. In the past, this enzyme has been used in the form of a crude mixture of enzymes, however, recently we have purified this sulfatase for a new application in metabolomics-driven discovery of sulfated metabolites. To evaluate the substratespecificity of this promiscuous sulfatase, we have synthesized a series of new sulfated metabolites
