Drug Detection

 

Detection Windows

A detection window is the time frame in which a drug can be detected within a biological sample. A cut-off level is applied which allows results to be classified as either positive or negative. The detection window is the period of time in which the level of drug can be identified as being above or below this cut-off.

Urine

Urine is the most common sample type for drug testing and offers a longer detection window than oral fluid for drugs.

Detection Window:

Drugs: 12 hours – 12 days
(drug dependent)

Alcohol: Maximum of 24 hours
(dependent on quantity ingested)

Oral Fluid

Oral fluid testing analyses a saliva sample for parent drugs and their metabolites, providing analysis of short-term drug abuse.

Detection Window:

Drugs: Up to 24 – 48 Hours
(drug dependent)

Hair

A hair drugs test offers a longer window of detection than alternative testing and can provide a detailed view or overall picture of drug or alcohol use.

Detection Window:

Based entirely on hair length

Head hair: 1cm is equal to a detection window of approximately 1 month

Body Hair: Can be used to provide an extended window of up to 1 year

Breath

Breath can be tested for alcohol using hand-held devices which provide immediate results. These devices can gauge blood alcohol content (BAC) by measuring deep lung air.

Detection Window:

Maximum of 24 hours
(dependent on quantity ingested)
