In recent times, drug testing methods often incorporate hair follicle testing. Employers, legal entities, and substance abuse specialists increasingly prefer this test over the traditional urine test. Hair follicle tests are favored by zero-tolerance employers, courts, and probation services due to their extended detection window of up to 90 days, observed collection process, and resilience against tampering. Nonetheless, for recent drug use within five days, urine testing remains highly accurate.

Hair strand analysis is recognized as an effective method for identifying drug and alcohol use. Hair fibers capture biomarkers within the growing strands, providing a long-term account of drug and alcohol usage. When taken near the scalp, hair can offer a detection period of up to roughly 90 days for alcohol and drugs. The collection process for hair is straightforward, challenging to tamper with, and simple to transport.
Using a 1.5-inch section of about 200 hairs (approximately the thickness of a #2 pencil) from just above the scalp provides a 100mg sample, an ideal quantity for initial and confirmatory testing. For EtG tests, additional panels, or assessments exceeding 10 panels, a 150mg sample is optimal. It's advisable to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent amount of body hair can be collected. Reference to head hair specifically denotes scalp hair, while body hair includes all other types (facial, armpit, etc.).
Process Overview
The processing of a drug test result in the lab comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initiation of sample processing within the lab system. This process ensures the sample was well-sealed and properly shipped, assigns a Laboratory Accessioning Number (LAN), and completes any missing data entry absent from an electronic chain of custody system.
Screening serves as an initial rapid assessment for the presence of drug abuse. While cost-effective for eliminating drug use in most specimens, a positive screen result must be confirmed to hold up in legal settings. Samples flagged as presumptively positive during Screening require further verification.
Should the Screening phase indicate a presumptive positive, additional hair is drawn from the original sample for Extraction. In this phase, drugs are refined from hair at much lower concentrations than other methods (such as urine or oral fluid), highlighting hair drug screening as the most complex method to execute.
To validate any positive screening findings, techniques like GC/MS, GC/MS/MS, or LC/MS/MS are utilized. Presumptively positive samples undergo washing prior to confirmation where necessary. Every step from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair classification and adheres to ISO / IEC 17025 standard accreditation.
