Hair Follicle Drug Testing - Luke, MD

What it is, How it works

The assessment of hair has become recognized as a robust means for identifying the presence of drug and alcohol use. Hair provides an extensive history of alcohol and other substances by capturing biomarkers within the fibers of the growing hair strand. When gathered near the scalp, hair can reveal a detection window for alcohol and drugs of up to roughly three months. Collecting hair is straightforward, moderately difficult to tamper with, and simple to transport.

A sample measuring 1.5 inches, containing about 200 strands of hair (similar to the width of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample size for screening and confirmation. For EtG, additional panels, and/or tests beyond 10 panels, 150mg of the specimen is advisable. It's recommended to measure the specimen using a jeweler’s scale. If scalp hair isn't available, an equivalent amount of body hair is collectible. When discussing head hair, it specifically refers to scalp hair only. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial processing of a specimen into a laboratory's system. This step includes confirming that the sample was sealed and shipped correctly, allocating a random LAN (Laboratory Accessioning Number), and filling in any additional data not provided by an electronic chain of custody system.

Screening is a preliminary check for substance abuse. While Screening is a cost-efficient way to eliminate drug usage for most samples, a positive result needs confirmation to be acceptable in court. Any samples yielding a presumptive positive result in Screening must undergo further confirmation.

If Screening shows a presumptive positive result, additional hair is extracted from the initial sample and prepared for Extraction. During Extraction, drugs are drawn from hair at significantly lower concentrations than in other methodologies (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.

Confirmation of any positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleaned before confirmation as necessary. The complete laboratory procedure, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, in contrast to urine tests, which have a shorter detection period.
• Challenging to manipulate: It is significantly challenging to deceive a hair drug test, thereby increasing result accuracy.
• Offers retrospective data: It can display a pattern of drug use over time, rather than just recent usage.

Limitations:

• Inability to detect recent use: It takes approximately 5-7 days for substances to become detectable in hair.
• Expense: Compared to other drug testing methods, hair drug tests tend to be more costly.
• Result variability: Factors like hair color and personal differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Although often termed "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp
