The trend in drug testing now increasingly features hair follicle tests. Preference for hair drug testing over urine tests is rising among employers, courts, and Substance Abuse experts. These tests are favored by employers with strict no-drug policies, as well as courts and probationary services. The key advantage is a more extensive detection window of up to 90 days, collected under supervision and difficult to fake. However, urine tests remain the most precise for use within the past 5 days.

Hair testing is increasingly recognized as an adept method for identifying drug and alcohol consumption. Hair maintains a comprehensive record of alcohol and drug intake by encapsulating biomarkers within its fibers as it grows. When cut close to the scalp, hair can reveal drug or alcohol use over a span of up to about 3 months. The collection of hair is straightforward, somewhat resistant to tampering, and convenient for transportation.
A sample of 1.5 inches, consisting of approximately 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for analysis and confirmation. For EtG testing, additional screens, or those beyond 10 panels, a specimen of 150mg is advisable. It's suggested to measure the specimen with a jeweler's scale. Should scalp hair be unavailable, a similar amount of body hair can be collected. "Head hair" solely refers to scalp hair, whereas "body hair" encompasses all other hair forms (such as facial and axillary hair).
Process Overview
There are four primary stages in the laboratory analysis for a drug test result: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample is initially integrated into a laboratory’s system. This stage involves checking the proper sealing and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic custody chain system.
Screening entails a preliminary rapid assessment for drugs of abuse. Although Screening is an economical approach to dismiss drug usage in most samples, a positive result needs verification to be permissible in legal contexts. Any samples that are presumptively positive in Screening require subsequent confirmation.
If a sample tests presumptively positive during Screening, additional hair is extracted from the original specimen and organized for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), which is why hair drug testing is considered one of the most challenging methodologies to execute.
Any positive results from Screening require Confirmation through methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive undergo washing prior to confirmation if needed. The comprehensive laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 standards.
