Recently, hair follicle drug testing has gained prominence for its effectiveness. Employers, courts, and substance abuse professionals often prefer it over traditional urine tests. Hair follicle testing is favored by companies enforcing strict drug-free policies, judicial bodies, and individuals on probation. Its primary advantage lies in a detection period lasting up to 90 days, ensuring an accurate collection process that is difficult to tamper with. Nonetheless, urine tests remain superior for detecting recent drug use within five days.

Hair testing is recognized as an effective method for detecting substance use, including alcohol. It offers an extended historical view of substance use by capturing biomarkers within the strands as hair grows. Collecting hair near the scalp can give a detection period of up to three months for substances like alcohol and other drugs. The process of gathering hair is straightforward, hard to tamper with, and easy to send for testing.
A hair sample of 1.5 inches consisting of roughly 200 strands (around the thickness of a #2 pencil) near the scalp provides 100mg, which is the standard amount for screening and confirmation. For EtG, additional tests beyond 10 panels need 150mg. We advise confirming the sample's weight using a jeweler’s scale. In cases where scalp hair is not available, a comparable amount of body hair can be used. "Head hair" specifically refers to scalp hair, whereas "body hair" includes any other types such as facial or axillary hair.
Process Overview
Laboratory processing of a drug test result consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
In the Accessioning phase, the sample is initially processed into a laboratory's system. This step includes ensuring the sample was correctly sealed and shipped, assigning it a unique Laboratory Accessioning Number (LAN), and capturing any additional data that might be missing from an electronic chain of custody system.
Screening provides a preliminary check for drugs of abuse. Although Screening is a cost-efficient means to exclude drug usage in most cases, any positive findings in Screening must be verified for legal acceptance. Presumptive positives from Screening need further confirmation.
For samples that test presumptively positive during Screening, additional hair is extracted from the original sample for the Extraction phase. Drugs are extracted at very low concentrations compared to other tests like urine or oral fluid, making hair drug screening the most challenging methodology to conduct.
Confirmation of positive Screening results is performed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All positive samples undergo washing as necessary before confirmation. The complete laboratory workflow from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair designation and in compliance with ISO / IEC 17025 standards.

Note: Although termed "hair follicle tests," the analysis is conducted on the hair strand rather than the follicle beneath the scalp.
