Equipment used to perform presence/absence tests:

Single use kits and a portable analysing unit enabling detection of the eight most wanted classes of molecules.Based on the Ascend MultimmunoAssay Technology, these tests are widely used throughout the world and largely documented, and they provide a well-defined specificity.

This equipment offers:

• Quick diagnosis: Result obtained within 15 minutes on location.
• High reliability: Guaranteed by the calibration process and automated control of the analysis equipment.
• Ease of use: Test is handled once. Results are displayed and stored automatically, eliminating the risk of incorrect results caused by human error.
• High accuracy, specificity and sensitivity :

	Précision %	Spécificité %	Sensibilité %
Methadone	100	100	100
Benzodiazepines	97	99	94
Cocaine	100	100	100
Amphetamines /metamphetamines	99	100	99
Tetrahydrocannabinol	100	100	100
Opiates	100	100	100
Barbiturates	100	100	100
Tricyclic antidepressants	99	98	99

• Detection according to the positive levels established by the recommendations of the SAMHSA/NIDA (Substance Abuse and Mental Health Services Administration/National Institute on Drug Abuse):

Methadone	300 ng/ml
