Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair offers a long-term record of alcohol and drug use by capturing biomarkers in the strands as they grow. When gathered near the scalp, hair may offer a detection timeframe of up to three months for alcohol and drugs. Collecting hair is straightforward, relatively tamper-resistant, and easy to mail.
A sample measuring 1.5 inches with roughly 200 hair strands (comparable to the girth of a #2 pencil) nearest to the scalp provides 100mg of hair, the optimal amount for analysis and verification. For additional EtG tests or those exceeding 10 panels, a 150mg sample is suggested. We advise using a jeweler’s scale for precision. If scalp hair is inadequate, an equal volume of body hair might be used. When discussing head hair, it pertains solely to scalp hair. Body hair encompasses all other forms (face, armpit, etc.).
Process Overview
The primary phases in the lab analysis of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial intake of the sample into a lab’s system. This process involves checking the sample's seal and shipping status, generating a random LAN (Laboratory Accessioning Number), and performing any extra data entry not covered by an electronic chain of custody system.
Screening entails a preliminary evaluation for drugs of interest. While it is economical for excluding drug usage in most samples, a positive result in Screening requires confirmation for legal acceptability. Samples that indicate presumption of positivity in Screening must undergo further validation.
If a sample shows presumed positivity during Screening, additional hair is extracted from the original sample for Extraction. During this phase, hair releases drugs in lower concentrations compared to other methods (such as urine or saliva), which explains the complexity of hair drug testing.
Confirmation of any positive results from Screening occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All samples suspected of being positive are washed before confirmation if necessary. Every stage from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Limitations:
Note: Although commonly labeled as "hair follicle tests", the analysis actually targets the hair strand rather than the follicle beneath the scalp
