Advancements in hair testing have made it an effective method for identifying drug and alcohol consumption. Hair can capture a long-standing record of alcohol and drug intake by embedding biomarkers within the strands of hair as they grow. When hair is collected near the scalp, it can offer a detection window of up to about 3 months for substances such as alcohol. Collecting hair is straightforward, relatively hard to tamper with, and convenient to transport.
A 1.5-inch segment consisting of roughly 200 strands of scalp hair, which is comparable to the size of a #2 pencil, yields approximately 100mg of hair, the optimal amount for both initial screening and further testing. For EtG, supplementary tests, or screenings beyond 10 panels, a sample of 150mg is advisable. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair cannot be obtained, an equivalent amount of body hair may be used instead. References to head hair specifically indicate scalp hair, while body hair encompasses all other types (such as facial and axillary hair).
Process Overview
The laboratory processing of a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample gets entered into a laboratory's system. This phase includes checking that the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry that an electronic chain of custody system hasn't already provided.
Screening is the next stage, which involves a preliminary examination for the presence of drugs. While this method is cost-effective for eliminating most drug usage cases, a positive screen needs corroboration for legal admissibility. Samples that indicate potential positivity during Screening must undergo secondary confirmation.
If a sample shows potential positivity during Screening, additional hair is extracted from the original sample for the Extraction phase. At this point, substances are extracted from hair at significantly lower concentrations than in other methods (such as urine or oral fluid), making hair drug testing one of the most challenging methods to perform.
Confirmation of any positive screening findings is conducted using technologies like GC/MS, GC/MS/MS, or LC/MS/MS. All samples that show potential positivity are thoroughly cleaned before confirmation as necessary. The comprehensive laboratory process, from Accessioning to Confirmation, is reviewed in compliance with both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often called "hair follicle tests", the examination evaluates the hair strand rather than the follicle beneath the scalp.
