  • Rapid screening test for smith-lemli-opitz syndrome
    Patent number: 5629210
    Abstract: A rapid screening test was used to distinguish between blood of normal infants and that of individuals having the Smith-Lemli-Opitz Syndrome (SLO). Blood was spotted on filter paper and analyzed with no extractions or separations. The method comprises the steps of vaporizing a cholesterol containing organic sample, ionizing the vaporized sample, detecting fragment ions of said vaporized ionized sample, and determining the intensity ratio of said fragment ions for cholesterol/7-dehydrocholesterol in the sample. The method includes performing the analysis by time-of-flight secondary ion mass spectrometry without derivation or chemical steps.
