  • Patent number: 5185267
    Abstract: An improved method for detecting the presence of durg metabolites in the meconium of newborn infants is described. The method involves a single step extraction of the drug metabolites from meconium using a buffered aqueous solution containing methanol in an amount between about 10 and 30% by volume and buffered to a pH between 6 and 7 and then assaying the extract individually for the presence of the drug metabolites. The method is particularly useful for detection of cocaine, morphine, cannabinoid and amphetamine metabolites; however, any drug metabolite in the infant meconium can be tested if it is extracted by the solution from the meconium. Various assay methods are used for the drug metabolites in the solutions derived from the meconium, including immunoassays, fluorescent assays and mass spectroscopy. The method provides for early detection of drug presence in newborn infants which contribute to infant illness.

  • Patent number: 5015589
    Abstract: A method for detecting the presence of drug metabolites in the meconium of newborn infants is described. The method involves separation of the drug metabolites from meconium in solution and then assaying the solution for the presence of the drug metabolites. The method is particularly useful for detection of cocaine, morphine and cannabinoids; however, any drug metabolite in the infant meconium can be tested. Conventional assay methods are used for the drug metabolites in the solutions derived from the meconium. The method provides for early detection of drug presence in infants which contribute to infant illness.
