Hair analyses have gained recognition as an effective method for identifying substance consumption. By capturing biomarkers within the fibers of the growing hair strand, hair provides an extended history of alcohol and drug use. When taken near the scalp, hair can offer a detection period of approximately three months for various substances. The collection process for hair is straightforward, challenging to tamper with, and convenient for shipment.
Collecting a 1.5-inch sample of around 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, the recommended amount for screening and verification. For EtG, add-ons, and tests beyond 10 panels, 150mg of specimen is suggested. We advocate for measuring the specimen on a jeweler’s scale. In the absence of scalp hair, an equivalent volume of body hair can be used. Head hair specifically refers to scalp hair, whereas body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug tests consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial integration of a sample into a lab’s system. This step ensures the sample is sealed and shipped correctly, a random LAN (Laboratory Accessioning Number) is assigned, and any supplementary data entry not covered by an electronic chain of custody system is completed.
Screening is a rapid assessment for drugs of abuse. It serves as a cost-effective method to eliminate drug usage in most samples, yet a positive screen must be validated for legal acceptance. Samples that indicate possible positivity during Screening require additional confirmation.
If a specimen shows potential positivity during the Screening phase, further hair is extracted from the original sample for the Extraction stage. Here, drugs are retrieved from hair at a considerably lower concentration than other techniques (e.g., urine or oral fluid), which makes hair drug screening notably complex.
Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All samples indicating possible positivity are cleansed before confirmation as necessary. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Typically termed "hair follicle tests," the test examines the hair strand itself, rather than the follicle under the scalp.
