The invention provides methods for quantifying enzymatic activity of an enzyme with a known substrate. The methods employ SELDI-TOF mass spectrometry, and are suitable, in particular, for assaying aspects of the renin-angiotensin system. The methods may be utilized to assess and/or monitor biological conditions associated with the renin-angiotensin system prior to the manifestation of known physiological and biomarkers for such conditions. The methods are suitable for analysis of pharmacological effectors of the renin-angiotensin system, and are particularly suitable for automation and high-throughput screening assay design.
