Hair testing is now acknowledged as a robust method for detecting the use of drugs and alcohol. Hair captures a long-term history of alcohol and drugs by ensnaring biomarkers within the strands of the growing hair. Collected near the scalp, hair can reveal a detection window spanning up to roughly three months for alcohol and drugs. It is easy to collect, relatively hard to tamper with, and simple to ship.
A sample of 1.5 inches containing around 200 hair strands (akin to the thickness of a #2 pencil) near the scalp amounts to 100mg of hair, the perfect sample size for screening and confirmation. For EtG, additional services, and/or testing exceeding ten panels, a specimen of 150mg is advisable. We suggest using a jeweler’s scale for weighing the sample. If scalp hair is not available, a matching amount of body hair can be collected. By head hair, we solely mean scalp hair. Body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first phase, where a sample is processed into a laboratory’s system. This incorporates verifying the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input not provided through an electronic chain of custody system.
Screening is a preliminary rapid check for drugs of abuse. Although Screening effectively rules out drug use for most samples, a positive result needs validation to be eligible in court. Samples showing a presumptive positive result in Screening necessitate a secondary confirmation.
If Screening indicates a presumptive positive, more hair is extracted from the sample for the Extraction process. Here, drugs are extracted from hair in much lower concentrations compared to other methods (such as urine or oral fluid), which is why hair drug screening is considered the hardest methodology to execute.
Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo washing as required. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although frequently called "hair follicle tests", the analysis is conducted on the hair strand itself and not the follicle beneath the scalp.
