1994 journal article
Quantitative Measurement of Cyclosporin A in Blood by Time-of-Flight Mass Spectrometry
Analytical Chemistry, 66(14), 2362–2368.
MeSH headings : Chromatography, High Pressure Liquid; Cyclosporine / blood; Fluorescence Polarization Immunoassay; Humans; Mass Spectrometry; Spectrometry, Mass, Fast Atom Bombardment
TL;DR:
Blood samples were analyzed by a nonspecific method, fluorescence polarization immunoassay (FPIA), and by a specific method, high-performance liquid chromatography (HPLC), and the TOF-MS results are in good agreement with the HPLC results, but not with the FPIA results.
