In recent times, drug testing methods have increasingly leaned toward hair follicle drug tests. More employers, courts, and substance abuse experts are opting for hair drug tests over conventional urine tests. These tests cater to employers with zero-tolerance drug policies, judicial systems, and those on probation. The main advantage of hair follicle drug tests is their extended drug detection window, generally up to 90 days, ensuring an observed collection procedure and making evasion nearly impossible. However, urine tests remain the most precise for screening drug use within the last five days.

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. The hair captures biological markers within the strands, providing a comprehensive timeline of substance use. When collected at the scalp's base, hair can offer up to a three-month detection period for drugs and alcohol. Hair samples are easy to gather, challenging to tamper with, and simple to send.
A sample measuring 1.5 inches in length with about 200 hair strands (approximately the thickness of a #2 pencil) near the scalp provides 100mg of hair, which is optimal for testing. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advised. Specimens should be weighed with a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair can be used. "Head hair" specifically refers to scalp hair, while "body hair" includes all other types (such as facial or axillary hair).
Process Overview
The laboratory processing of a drug test encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the sample is first processed within the lab’s system by confirming proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and inputting any additional information not provided by an electronic chain of custody system.
Screening serves as an initial quick assessment for substances of abuse. Although Screening efficiently rules out drug use in most cases, any positive results must be authenticated to be valid in legal proceedings; thus, presumptive positive screenings necessitate further verification.
When a sample shows presumptive positivity during Screening, additional hair is derived from the original sample and readied for Extraction. This phase involves extracting drugs from hair at lower concentrations than other methods (like urine or oral fluid), highlighting the complexity of hair drug analysis.
The Confirmation phase uses GC/MS, GC/MS/MS, or LC/MS/MS for validating positive screenings. All samples marked as presumptive positive undergo washing before Confirmation if needed. Each phase, from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Though termed "hair follicle tests", the actual analysis examines the hair strand rather than the follicle beneath the scalp.
