Recent advances in the field of doping detection.

Patterns of doping in Britain have on the whole changed from the use of CNS stimulants and depressants to therapeutic substances, or to accidental doping by feeding contaminated food or food supplements. Progress in detection and identification is largely a result of improvements in separation and isolation, especially by gas chromatography, together with the introduction of mass spectrometry. Radiommunoassay and high performance liquid chromatography promise to be important techniques in the future, especially in detection of anabolic steroids and corticosteroids.
