Hair Follicle Drug Testing - Chevy Chase, MD

What it is, How it works

Hair analysis has emerged as a significant means for assessing drug and alcohol consumption. Hair serves as a long-lasting record by embedding biomarkers within the fibers of the developing hair strand. When sourced near the scalp, hair can reveal a detection period of up to roughly 3 months for alcohol and various drugs. Collecting hair is straightforward, relatively tamper-proof, and convenient for transportation.

A hair sample measuring 1.5 inches, consisting of about 200 strands (akin to a #2 pencil), nearest to the scalp provides 100mg of hair, which is the optimal sample size for initial testing and verification. When dealing with EtG, supplementary tests, and/or testing beyond 10 panels, 150mg of the specimen is advised. Utilizing a jeweler’s scale for weighing the specimen is recommended. Should scalp hair be unavailable, an equal quantity of body hair may be sourced. References to head hair pertain specifically to scalp hair solely, whereas body hair denotes any other hair types (such as facial, axillary, etc.).

Process Overview

The primary steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves introducing a sample into a laboratory system. This step includes ensuring the sample was properly sealed and sent, allocating a random LAN (Laboratory Accessioning Number), and completing additional data entry not covered by an electronic chain of custody system.

Screening consists of an initial cursory check for illicit substances. Although Screening is an affordable method for excluding drug use in most samples, a positive screening result must be verified to hold up in legal proceedings. Any samples that are initially positive in Screening require further confirmation.

If a sample is initially positive in the Screening phase, additional hair is extracted from the original specimen and prepared for Extraction. This stage involves extracting drugs at a significantly lower concentration from hair than through other techniques (e.g., urine or oral fluid), highlighting hair drug analysis as the most challenging technique to execute.

Any positive results from Screening are verified through GC/MS, GC/MS/MS, or LC/MS/MS. All initial positive samples are cleansed prior to confirmation as necessary. The comprehensive lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can uncover drug use for up to 90 days, in contrast to urine tests which feature a briefer detection span.
• Hard to manipulate: Manipulating a hair drug test is exceedingly challenging, which enhances the reliability of the findings.
• Offers historical insights: The test can identify a pattern of drug usage over a timeframe, not solely recent usage.

Limitations:

• Inability to detect recent use: Drugs require about 5-7 days to become detectable within hair.
• Costly: Hair drug testing is generally pricier than other drug testing approaches.
• Inconsistent results: Variabilities like hair color and personal growth variance can influence drug metabolite concentration in hair.

Note: Often termed as "hair follicle tests", the test evaluates the hair strand itself and not the follicle beneath the scalp
