Described is a method to determine the viability of cells by measuring the absolute and relative rate of metabolic activity and/or integrity of the cell membrane through the use of vibrational spectroscopy. The use of deuterated agents facilitates detection of changes associated with a change in viability.

tandem mass spectrometry (LC–MS/MS) is a highly specific and sensitive technique for measuring metabolites. However, coeluting components in tissue extracts can interfere with ionization at the interface of the LC and MS/MS phases, causing under- or overestimation of metabolite concentrations. Spiking of samples with known amounts of stable-isotope-labeled internalstandards (SIL-IS) allows measurements
