Hair Follicle Drug Testing - Graham, AL

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol usage. Hair retains a comprehensive record of alcohol and drug consumption by embedding biomarkers within its fibers as it grows. When sourced near the scalp, hair samples offer a detection window of up to about three months for alcohol and drugs. The collection process is straightforward, resistant to tampering, and facilitates easy shipping.

A sample measuring 1.5 inches and consisting of approximately 200 hair strands (roughly equivalent in size to a #2 pencil) can yield 100mg of hair, which is an ideal quantity for both screening and confirmation. For EtG, add-ons, and/or tests above 10 panels, a specimen weighing 150mg is suggested. Using a jeweler's scale for measurement is advisable. If scalp hair isn't available, body hair in a similar quantity can be used. When mentioning head hair, this specifically relates to scalp hair. Body hair encompasses all other types, including facial and axillary.

Process Overview

The laboratory procedure for processing a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning initiates the process by entering a sample into the laboratory's system. This step verifies the sample's proper sealing and shipment, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry not addressed by an electronic chain of custody system.

Screening provides an initial assessment for drug abuse presence. It is cost-efficient for excluding drug usage in most samples; however, a positive result in Screening requires confirmation to be court-admissible. Samples showing presumptive positivity require further confirmation.

For samples flagged as presumptively positive during Screening, additional hair is taken from the original specimen for the Extraction phase. In this stage, drugs are extracted from the hair in much lower concentrations than in methods like urine or oral fluid analysis, which adds to the complexity of hair drug screening.

Confirmation of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before confirmation, if needed. The complete laboratory workflow from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests, which have a shorter timeframe.
• High resistance to tampering: Cheating on hair drug tests proves very challenging, enhancing result accuracy.
• Chronological usage information: Provides a timeline of drug consumption, extending beyond immediate use.

Limitations:

• Inability to detect recent usage: Detection in hair requires approximately 5-7 days post-consumption.
• Expense: Hair tests generally incur higher costs than alternative drug testing methods.
• Result variability: Influences like hair color and individual hair growth differences can affect metabolite concentrations in hair.

Note: While colloquially known as "hair follicle tests," the analysis targets the hair strand rather than the follicle beneath the scalp.
