Hair screening is now recognized as an effective method for identifying substance and alcohol consumption. Hair captures a prolonged history of chemical and alcohol presence by embedding biomarkers within the fibers of hair as it grows. When taken close to the scalp, hair offers up to roughly a three-month detection timeframe for drugs and alcohol. It is straightforward to collect, relatively challenging to tamper with, and effortless to transport.
A 1.5-inch portion consisting of about 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp will yield 100mg, which is the optimal amount for examination and verification. For EtG, extra tests, and/or panels exceeding 10, a 150mg sample is advised. It is suggested to measure the sample on a jeweler’s scale. If scalp hair is unavailable, an equivalent quantity of body hair can be used. 'Head hair' refers exclusively to scalp hair. 'Body hair' pertains to all other types such as facial or axillary hair.
Process Overview
The key stages in the laboratory evaluation of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a specimen into the laboratory's framework. This involves ensuring the sample has been correctly sealed and transported, generating a random LAN (Laboratory Accessioning Number), and performing any extra data recording not covered by an electronic chain of custody system.
Screening comprises an initial swift analysis for illicit drugs. Although Screening provides a cost-efficient method to exclude drug presence in most samples, confirmation of a positive result is necessary for legal acceptance. Samples identified as presumptively positive during Screening require further conclusive verification.
If Screening indicates presumptive positivity, additional hair is extracted from the initial sample and prepared for Extraction. During this phase, drugs are retrieved from hair at a significantly reduced concentration compared to other methods (e.g., urine or oral fluid), which is why hair drug screening is notably complex.
Positive Screening outcomes are verified through methodologies like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity go through a cleansing process before confirmation if necessary. The full laboratory process, from Accessioning through to Confirmation, adheres to both CAP (College of American Pathologists) Hair protocols and the accreditation under ISO / IEC 17025 standards.

Note: Although sometimes called "hair follicle tests", the evaluation focuses on the hair strand and not the scalp’s hair follicle.
