Assay of teicoplanin in serum: comparison of high-performance liquid chromatography and fluorescence polarization immunoassay.

A simple liquid extraction coupled with reverse-phase HPLC and UV detection was shown to correlate well with fluorescence polarization immunoassay (FPIA) on the Abbott TD(x) analyser for serum teicoplanin analysis, r(2) = 0.974, HPLC = 0.908 TDx + 2.
