Teicoplanin measurement in patients with renal failure: comparison of fluorescence polarization immunoassay, microbiological assay, and high-performance liquid chromatographic assay.

abstract：:The emerging nation of South Africa, in common with some other countries, notably Eastern Europe, is heir to decades of neglect with regards to the exposure of the majority of its population to toxic materials. In this short review, the major toxic health hazards are described. For most of these risks there are now pr...
