Considered an effective means for identifying drug and alcohol consumption, hair testing offers an extensive historical record by embedding biomarkers within the fibers of the hair strand as it grows. When collected near the scalp, it can provide a detection span of up to approximately three months for alcohol and other drugs. This method of collection is straightforward, somewhat resistant to tampering, and convenient to transport.
A sample of 1.5 inches, comprising about 200 hair strands (comparable to the diameter of a #2 pencil), close to the scalp yields 100mg of hair, which is ideal for initial testing and validation. For EtG and additional testing or tests exceeding ten panels, 150mg of the hair sample is advised. It is recommended to weigh the sample using a jeweler's scale. Should scalp hair be unavailable, an equivalent quantity of body hair may be gathered. "Head hair" pertains specifically to scalp hair, while "body hair" includes other types such as facial and axillary hair.
Process Overview
The key steps in laboratory processing of a drug test include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample within a laboratory’s system. This step confirms the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and finishes any additional data entry not handled by an electronic chain of custody system.
Screening is an initial rapid evaluation for drugs of abuse. Although Screening is a cost-effective method to eliminate drug use in most cases, a positive screen needs further confirmation to be legally admissible. Presumptive positives from Screening require another confirmation step.
When a sample shows a presumptive positive result during Screening, more hair from the initial sample is used in the Extraction stage. During Extraction, drugs are isolated from hair at a much lower concentration compared to other methods (like urine or oral fluid), which is why hair drug screening presents the greatest challenge.
Confirmation of any screening positive is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation when necessary. The entire laboratory process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and aligned with ISO / IEC 17025 standards.

Note: Although commonly termed "hair follicle tests," the analysis focuses on the hair strand, not the follicle beneath the scalp.
