EV ALUA TION OF A RAPID ORAL FLUID POINT OF CARE TEST FOR MDMA<br />

Recreational use <strong>of</strong> 3,4-methylenedioxymethamphetamine (MDMA) either alone or in combination with<br />

other drugs such as alcohol and cannabis has become increasingly popular among young people throughout<br />

the UK, Europe and the US. The Cozart® RapiScan oral fluid drug test system has been use successfully for<br />

monitoring compliance within treatment centres, criminal justice settings and more recently at the roadside.<br />

The aim <strong>of</strong> this study was to evaluate the Cozart® RapiScan test cartridge developed for the detection <strong>of</strong><br />

MDMA and methamphetamine in oral fluid. Fifty oral fluid samples were obtained from drug addicts<br />

attending drug dependency units and were screened initially using the Cozart® microplate ELISA for<br />

amphetamines. All samples were then screened using the Cozart® RapiScan test cartridge for MDMA<br />

followed by confirmation by gas chromatography-mass spectrometry (GC-MS).<br />

A total <strong>of</strong>23 samples screened positive and were confirmed for MDMA either alone or in combination with<br />

amphetamine. A further 15 samples were confirmed negative for all amphetamines by GC-MS and 14 <strong>of</strong><br />

these samples also screened negative using the Cozart® RapiScan. The false positive sample was<br />

investigated further and was found to contain an extremely high concentration <strong>of</strong> pseudoephedrine. The<br />

remaining 12 samples were confirmed positive for amphetamine only. Six samples screened negative and<br />

the other six screened positive due to the extremely high concentrations <strong>of</strong> amphetamine in these samples.<br />

No samples tested in this study contained methamphetamine.<br />

The Cozart® RapiScan Drug Test System for the detection <strong>of</strong> MDMA correctly identified 100% <strong>of</strong> MDMA<br />

~. positive samples ranging from 53nglmL to concentrations in excess <strong>of</strong> lS0ng/mL. False positive results<br />

were only observed when samples contained extremely high concentrations <strong>of</strong> amphetamine or<br />

pseudoephedrine, which is consistent with the cross reactivity pr<strong>of</strong>ile <strong>of</strong> the drug test.<br />
