What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. It offers a prolonged view of alcohol and drug use by locking in biomarkers within the fibers of the growing hair strand. When taken near the scalp, this method can provide a detection period of up to around three months for alcohol and other substances. Hair is easy to gather, challenging to tamper with, and simple to transport.

Collecting a 1.5-inch sample consisting of roughly 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp gives 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG, additional tests, and/or panels beyond 10, a 150mg sample is advised. Using a jeweler’s scale to measure the specimen is recommended. If head hair isn't available, a similar quantity of body hair can be utilized. "Head hair" refers exclusively to scalp hair. "Body hair" indicates all other forms (facial, axillary, etc.).

Process Overview

The key steps in the laboratory analysis of a drug test are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial handling of a sample into a lab’s system. This process assures that the sample is properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and fills in any missing data not included by an electronic chain of custody system.

Screening is a preliminary rapid analysis for substances of abuse. Although Screening is an economical way to determine drug usage for most samples, a positive result must be confirmed to be valid in judicial situations. Any presumptively positive Screening results do necessitate secondary confirmation.

In cases where a sample shows a presumptive positive in Screening, additional hair is obtained from the original specimen and set up for Extraction. During this phase, drugs are isolated from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), making hair drug testing more intricate to execute.

The Validation of any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo a washing process before confirmation if necessary. The full laboratory sequence from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair classification and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extensive detection period: Hair drug testing can identify substance use for up to 90 days, unlike urine tests which have a more limited detection timeframe.
  • Resistance to tampering: Cheating on a hair drug test is highly challenging, thus making the outcomes more trustworthy.
  • Records historical usage: It provides a timeline of drug consumption over a duration, not only recent usage.

Limitations:

  • Cannot uncover recent usage: Drugs become detectable in hair after approximately 5-7 days.
  • Expense: Hair drug tests tend to be pricier than other drug testing techniques.
  • Result variability: Elements like hair color and individual differences in hair growth can influence the presence of drug metabolites in the hair.

Note: The term "hair follicle tests" is often misleading, as the assessment examines the hair strand, not the follicle beneath the scalp.
