Hair Follicle Drug Testing - Parrott, VA

What it is, How it works

Hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. By encapsulating biomarkers within the strands of hair as it grows, hair offers a detailed history of alcohol and substance use. When collected near the scalp, hair can offer up to roughly a 3-month detection period for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches containing roughly 200 hair strands (similar to the girth of a #2 pencil) closest to the scalp yields 100mg of hair, the optimal amount for both screening and verification. For EtG, additional tests, and/or screenings beyond 10 panels, 150mg of the specimen is advised. It is best to measure the specimen using a jeweler’s scale. In cases where scalp hair is unavailable, an equivalent quantity of body hair can be used. References to head hair indicate scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory process for drug test results involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of integrating a specimen into the laboratory’s system. This process includes ensuring the sample was sealed and dispatched appropriately, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data input that might be missing from an electronic chain of custody system.

Screening consists of a preliminary assessment for substances of abuse. While Screening provides a cost-effective means to eliminate drug usage in most samples, positive screens must be confirmed for them to be valid in legal situations. Samples with presumptive positive outcomes in Screening necessitate a subsequent confirmation.

Should a sample test presumptively positive during the Screening phase, additional hair is extracted from the primary specimen and prepped for Extraction. In this phase, drug compounds are extracted from the hair at a far lower concentration than in alternative methods (e.g., urine or oral fluid), making hair drug testing the most challenging methodology to execute.

Positive screening results are confirmed through methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo necessary washing before confirmation. The comprehensive laboratory steps from Accessioning to Confirmation are evaluated under the guidelines of CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can identify drug use up to 90 days, unlike urine tests which offer a shorter detection window.
• Hard to deceive: Manipulating a hair drug test is extremely challenging, which increases result accuracy.
• Offers historical insight: It reveals a timeline of drug consumption over an extended period, not merely recent usage.

Limitations:

• Fails to identify recent use: Drugs become detectable in hair only after about 5-7 days.
• Expense: Typically, hair drug tests cost more compared to other drug test methods.
• Result variability: Elements such as hair color and personal differences in hair growth can impact drug metabolite concentrations in hair.

Note: Commonly labeled as "hair follicle tests", the analysis concerns the hair strand rather than the follicle beneath the scalp.
