Typically, 1.5 to 2 inches of crown or body hair is necessary. These tests detect drugs, alcohol/ETG, or other tailored options through hair analysis.
Recently, hair follicle testing has become a more common method for drug screening. Many workplaces, courts, and substance abuse specialists now prefer hair drug tests over the standard urine test. Companies with zero-tolerance drug policies, legal institutions, and probation cases choose this method. Its primary advantage is the extended detection period of up to 90 days, with observed collection, making it hard to tamper with. However, urine tests remain the most precise for identifying recent drug use (within five days).

Hair testing is regarded as an effective method for identifying drug and alcohol use. Hair captures a prolonged history of alcohol and other drugs by embedding biomarkers within the strands of hair as they grow. When taken from near the scalp, hair can indicate drug and alcohol use over a period of up to around three months. The collection process for hair is straightforward, hard to tamper with, and convenient to transport.
A sampled length of 1.5 inches of approximately 200 hair strands (comparable to a #2 pencil in size) taken nearest the scalp yields 100mg, which is the optimal sample size for both screening and follow-up testing. For EtG, additional tests, and/or tests beyond 10 panels, a specimen weight of 150mg is recommended. It is advisable to use a jeweler’s scale to weigh the specimen. If scalp hair is inaccessible, an equivalent quantity of body hair can be procured. 'Head hair' specifically refers to scalp hair alone. 'Body hair' encompasses all other types, including facial and axillary hair.
Process Overview
The procedural stages in the lab processing of a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves initially entering a sample into a laboratory’s system. This step includes checking the sample for proper sealing and shipment, assigning it a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.
Screening entails a prompt preliminary check for drug abuse. Screening serves as a cost-effective strategy to eliminate drug use in most samples. However, if the screen is positive, it must be confirmed to be legally valid. Any samples showing a presumptive positive in Screening require a subsequent confirmation.
Where a sample shows a presumptive positive during the Screening phase, additional hair is extracted from the initial specimen and prepared for Extraction. Here, drugs are extracted from hair at a much lower concentration than with other techniques (e.g., urine or oral fluid), which is why hair drug screening stands as the most challenging methodology to conduct.
Confirmation of any positive result is carried out by means of GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes washing before confirmation if necessary. The entire lab process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and accreditation per ISO/IEC 17025 standards.
