Mass spectroscopy test can distinguish between those who have handled drugs and those who have taken them
Sweat from the fingertips could provide a more comfortable and convenient alternative to blood testing to check that patients are taking their antipsychotic drugs, UK researchers have found.
The researchers, who were based at the University of Surrey, collected finger sweat samples from 60 patients receiving treatment with clozapine, quetiapine or olanzapine, before and after a hand washing procedure, and analysed them using liquid–chromatography mass–spectrometry.
