In the last few years, drug screening methods increasingly favor hair follicle tests. Various professionals such as employers, courts, and substance abuse authorities now prefer hair drug tests to standard urine tests. Hair follicle tests cater to employers with zero-tolerance policies and court-mandated testing. While they offer a detection period of up to 90 days and feature an observed collection process to prevent tampering, urine tests remain more precise for detecting recent drug use within 5 days.

Hair analysis has gained recognition as an effective means for detecting drug and alcohol usage. Hair captures a long-term record of alcohol and drugs by preserving biomarkers in the hair's structure. If obtained near the scalp, hair offers up to a roughly 90-day detection period for alcohol and drugs. Collection is straightforward, hard to tamper with, and easily transportable.
A sample measuring 1.5 inches, consisting of approximately 200 hair strands (similar in size to a #2 pencil) close to the scalp yields 100mg, which is optimal for both screening and confirmation. For EtG, additional tests, or when tests exceed 10 panels, 150mg of the sample is suggested. It is advisable to use a jeweler’s scale for weighing. In the absence of scalp hair, the same quantity of body hair can be collected. Head hair specifically refers to scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The essential stages in processing a drug test result in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of initially handling a sample in the lab’s system. This step involves ensuring the sample’s proper sealing and shipping, assigning it a random LAN (Laboratory Accessioning Number), and performing any additional data entry not covered by an electronic chain of custody.
Screening performs an initial rapid assessment for substance abuse. Although Screening is a budget-friendly method to exclude drug use from most samples, a positive result requires confirmation for court validity. Samples that test presumptively positive during Screening necessitate a second confirmation.
In cases of a presumptively positive result during Screening, more hair is processed from the original sample for the Extraction phase. Here, drugs are removed from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), highlighting the intricate nature of hair drug analysis.
Confirming any positive Screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS systems. All samples that show presumptively positive results undergo a wash before Confirmation if necessary. The entire process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.
