Recently, drug testing methods have increasingly favored hair follicle tests. Employers, courts, and substance abuse experts often opt for hair tests over traditional urine tests. Hair follicle tests are preferred by organizations with strict drug use policies, legal entities, and for those on probation.

What it is, How it works

Hair analysis is recognized as an effective method for identifying substance and alcohol usage. Hair retains a long-term record of alcohol and drugs by embedding biomarkers within the structure of the hair strands. When taken from near the scalp, hair can offer a detection period of up to around three months for both alcohol and drugs. Hair is straightforward to collect, not easily tampered with, and simple to transport.

A 1.5-inch piece consisting of roughly 200 hairs (approximately the size of a #2 pencil) from the area nearest the scalp yields 100mg of hair, which is the perfect sample size for both screening and verification. For EtG, additional tests, and/or tests exceeding 10 panels, a 150mg sample is advisable. It is suggested to measure the specimen with a jeweler’s scale. If scalp hair isn't available, the same quantity of body hair may be used. When mentioning head hair, we specifically mean scalp hair. Body hair denotes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test includes four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial integration of a sample into a lab's system. This step involves checking that the sample was properly sealed and transported, allocating a random LAN (Laboratory Accessioning Number), and completing any other necessary data entry not covered by an electronic chain of custody system.

Screening is a preliminary rapid assessment for substances of abuse. While Screening is a budget-friendly method to exclude drug usage in most cases, a positive screening necessitates confirmation to stand up in court. Any screenings that return as presumptively positive require a subsequent confirmation step.

If a sample is marked presumptively positive at the Screening phase, more hair is extracted from the initial sample for the Extraction phase. In Extraction, drugs are isolated from hair at significantly lower concentrations than through alternative methods (like urine or oral fluid), which is why hair analysis is the most challenging methodology to conduct.

Confirmation of any positive screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that test positive presumptively are washed before confirmation as necessary. The overall laboratory procedure from Accessioning through Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests can detect substance use for up to 90 days, in contrast with urine tests, which have a shorter detection period.
  • Tough to manipulate: It is extremely difficult to falsify a hair drug test, ensuring more precise results.
  • Captures historical usage: It portrays a trend of drug use over time, not just recent usage.

Limitations:

  • Inability to detect recent use: It typically takes between 5-7 days for substances to become detectable in hair.
  • Expensive: Hair drug tests tend to be costlier compared to other drug test methods.
  • Result variability: Hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Despite commonly being called "hair follicle tests", this test examines the hair strand rather than the hair follicle beneath the scalp.
