OBJECTIVE To determine women's responses to cervical interrogation by fluorescent and reflective spectroscopy (FRS). MATERIALS AND METHODS A convenience sample of women scheduled for a colposcopic examination was interrogated by a cervical FRS system. Thereafter, women completed a 24-item questionnaire that assessed their responses to the spectroscopic test. Likert-scale responses were compar...

We evaluated a new EMIT#{174} II monoclonal amphetamine! methamphetamine assay for screening human urine by comparing itwith the EMIT#{174} d.a.u. monoclonal amphetamine/methamphetamine assay and a fluorescence polarization assay. The EMIT II assay has a cutoff of 1 mg!L d-methamphetamine. The EMIT II and EMIT d.a.u. assays were run on a BM/Hitachi 704 analyzer; for the fluorescence polarizatio...
