Methods for detecting dihydroxyvitamin d metabolites by mass spectrometry |
| abstract |
There is provided a method for determining an amount of one or more dihydroxyvitamin D metabolites in a biological sample, when taken from a human, by tandem mass spectrometry, comprising: (i) generating a precursor ion of said one or more dihydroxyvitamin D metabolites by ionizing said one or more dihydroxyvitamin D metabolites with atmospheric pressure chemical ionization (APCI); (ii) generating one or more fragment ions of said precursor ion; and (iii) detecting an amount of one or more of said ions generated in step (i) or (ii) or both and relating the amount of detected ions to the amount of said one or more dihydroxyvitamin D metabolites in said sample; wherein said one or more dihydroxyvitamin D metabolites are not subject to derivatization. |
