Hair testing has become recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of substances by embedding biomarkers within the strands as they grow. When taken near the scalp, hair can offer a detection period of up to roughly three months for drugs and alcohol. Hair is easy to gather, relatively hard to tamper with, and straightforward to transport.
A 1.5-inch hair sample consisting of about 200 strands (approximately the thickness of a #2 pencil) near the scalp provides 100mg of hair, an optimal amount for screening and confirmation tests. For EtG, additional tests, or tests exceeding 10 panels, 150mg of the sample is advisable. Utilizing a jeweler’s scale for weighing the specimen is recommended. In the absence of scalp hair, a similar quantity of body hair can be collected. The term "head hair" refers exclusively to scalp hair, while "body hair" includes all other hair types (such as facial and axillary).
Process Overview
The principal stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning features the initial handling of a sample within a lab's system. This process confirms that the sample was securely sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not available via an electronic chain of custody system.
Screening serves as a preliminary swift evaluation for the presence of drugs. Screening is economically efficient for dismissing drug use in most cases, yet a positive screening requires further confirmation for legal admissibility. Any samples deemed presumptively positive during Screening necessitate an additional confirmation step.
Should a sample test presumptively positive during Screening, more hair is extracted from the original sample to prepare for Extraction. During this stage, drugs are extracted at a significantly reduced concentration compared to other methods (e.g., urine or saliva), which accounts for the complexity of hair drug screening.
The Confirmation of any positive screening involves methodologies such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity undergo washing before confirmation as necessary. From Accessioning through Confirmation, the entire process undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
