    摘要: Provided are methods for determining the presence or amount of testosterone in a test sample, comprising ionizing all or a portion of the testosterone present in the sample to produce one or more testosterone ions that are detectable in a mass spectrometer. All or a portion of the testosterone present in the sample is ionized to produce one or more testosterone ions, which may be isolated and fragmented to produce precursor ions. A separately detectable internal testosterone standard can be provided in the sample. In a preferred embodiment, the reference is 2, 2, 4, 6, 6-d5 testosterone.

    摘要: Provided are methods for reducing transfer of fluid between liquid samples subject to consecutive instrument controlled filter sampling. Transfer of fluid between subsequent samples is reduced by decontaminating surfaces of the instrument. The methods reduce sample contamination so that any remaining unused sample may be subject to diagnostic analysis without less concern that the outcome will be the result of sample cross-contamination.
