Many workplaces, judiciary bodies, and Substance Abuse experts now prefer hair testing over typical urine analysis. Hair follicle tests support zero-tolerance policies, legal orders, and probation checks. The main advantage is an extended detection window for substances, usually up to 90 days, with direct observation collection, enhancing test integrity. However, for recent drug usage within 5 days, urine tests remain the most precise.

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures and retains biomarkers within the fibers of the developing hair shaft, offering an extended overview of alcohol and drug usage. By obtaining samples near the scalp, hair testing can reveal substance use up to a 90-day period. Hair collection is straightforward, challenging to tamper with, and simple to send for analysis.
A 1.5-inch piece containing approximately 200 hair strands (equivalent to the width of a #2 pencil) taken next to the scalp yields 100mg, the preferred amount for testing. For EtG, additional markers, or panels exceeding 10, 150mg is suggested. It is advisable to weigh the sample using a jeweler’s scale. If scalp hair is not available, a corresponding portion of body hair is acceptable. References to head hair imply scalp hair solely, while body hair encompasses all other hair types (such as facial, underarm, etc.).
Process Overview
The process for laboratory analysis of a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial inputting of the sample into a laboratory's system. This process includes ensuring the sample was appropriately sealed and dispatched, allocating a unique LAN (Laboratory Accessioning Number), and completing any supplementary information not supplied by a digital chain of custody framework.
Screening performs a preliminary assessment for substance abuse. Although Screening is a cost-effective method to eliminate drug usage in most instances, any positive findings require confirmation for legal admissibility. Samples that show presumptive positives in Screening must undergo a follow-up confirmation.
If a sample registers as presumptive positive during Screening, additional hair is taken from the original sample for Extraction. During this phase, substances are extracted from the hair at significantly reduced concentrations compared to other methods (such as urine or oral fluid), making hair drug analysis one of the more complex testing methodologies.
Confirmation of any positive findings from Screening is achieved through GC/MS, GC/MS/MS or LC/MS/MS analysis. All samples with presumptive positives undergo a necessary pre-confirmation wash. The entire testing process, from Accessioning to Confirmation, aligns with both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.
