The Uppsala team presented at the Vårmöte klinisk kemi, 5-7 April in Tylösand, Sweden. Here Torbjörn is presenting our MS based assays for analysing PEth (a marker for alcohol consumption measured in blood) and cortisol/cortison measurements in urine. The methods have been in clinical use for more than a year now at Akademiska sjukhuset. Kim is also presenting an ultrasensitive method for detecting trace levels of levonorgestrel. The method is in use for detecting if lost contraceptive coils are present or not in the body, and the method can also be used for environmental monitoring in e.g. aquatic species.
