Assignee:
Quest Diagnostics Investments Incorporated - Wilmington DE
International Classification:
C12Q001/00
US Classification:
435 4
Abstract:
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-dtestosterone.

Abstract:
Provided are methods of detecting the presence or amount of a vitamin D metabolite in a sample using mass spectrometry. The methods generally comprise ionizing a vitamin D metabolite in a sample and detecting the amount of the ion to determine the presence or amount of the vitamin D metabolite in the sample. Also provided are methods to detect the presence or amount of two or more vitamin D metabolites in a single assay.

International Classification:
H01J 49/00 C12Q 1/00
US Classification:
250282, 250281, 435 71
Abstract:
Provided are methods for determining the amount of dihydrotestosterone (DHT) in a sample using mass spectrometry. The methods generally involve ionizing DHT in a sample and detecting and quantifying the amount of the ion to determine the amount of DHT in the sample.

US Classification:
250282, 250281, 250288, 250423 R, 250424
Abstract:
Provided are methods for measuring renin activity in a plasma sample using mass spectrometry. The methods generally involve ionizing purified angiotensin 1 from the sample and detecting the amount of angiotensin 1 ions generated. The amount of detected angiotensin 1 ions are then related to the amount of angiotensin 1 generated in the sample, which in turn is related to renin activity in the sample.

Abstract:
Provided are methods for determining the amount of underivatized dehydroepiandrosterone (DHEA) in a sample using mass spectrometry. The methods generally involve ionizing DHEA in a sample and detecting and quantifying the amount of the ion to determine the amount of DHEA in the sample.
