Hair Follicle Drug Testing - Naval Academy, MD

What it is, How it works

Hair analysis is now recognized as an effective resource for identifying drug and alcohol consumption. Hair offers a comprehensive timeline for alcohol and drugs by capturing biomarkers within the structure of the evolving hair shaft. When taken near the scalp, hair can reveal usage history of up to about three months for alcohol and drugs. Hair sampling is straightforward, hard to tamper with, and simple to send.

A sample of 1.5 inches, consisting of approximately 200 hair strands (approximating a #2 pencil), nearest to the scalp, will yield 100 mg of hair, which is the optimal quantity for testing and result confirmation. For tests like EtG, add-ons, and panels exceeding 10, 150 mg of the hair should be used. It is advised to use a jeweler’s scale for precise measurement. In the absence of scalp hair, a similar volume of body hair can be gathered. References to head hair solely pertain to scalp hair, while body hair encompasses all other hair (facial, axillary, etc.).

Process Overview

The laboratory procedure for drug test outcomes consists of four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary process where a sample is introduced into a lab's framework. It involves ensuring the sample's security during sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and completing any residual data entry not handled by an electronic chain of custody protocol.

Screening executes an immediate scan for substance abuse. While Screening offers a budget-friendly option to dismiss drug presence in most samples, a positive outcome necessitates confirmation for legal acceptability. Samples returning a positive Screening result demand secondary verification.

Should a sample exhibit a presumptive positive in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. At this juncture, drugs are isolated from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), justifying why hair drug testing is notably challenging to conduct.

Confirmation of all positive screening outcomes occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo cleansing prior to confirmation as necessary. The full laboratory protocol from Accessioning to Confirmation gets evaluated under the CAP (College of American Pathologists) Hair criteria and is consistent with accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can recognize drug use lasting up to 90 days, while urine tests present a briefer detection timeframe.
• Resistance to fraud: It's exceedingly challenging to deceive a hair drug test, thus enhancing result accuracy.
• Detailed usage record: It offers insights into drug consumption patterns over time, not merely recent usage.

Limitations:

• Incipient use undetectable: Drugs require about 5-7 days post-usage to become traceable in hair.
• Expense: Hair drug tests typically incur higher costs than alternative testing methods.
• Variable findings: Elements like hair color and individual growth differences can influence drug metabolite levels in hair.

Note: Despite often being called "hair follicle tests," the examination pertains to the hair strand, not the follicle beneath the scalp.
