Hair Follicle Drug Testing - Enka, NC

What it is, How it works

Hair testing is increasingly recognized as a potent method for detecting alcohol and drug use. Hair captures biomarkers within the fibers of the growing strand, offering a long-term history of substance use. Collecting hair near the scalp can provide a detection period of up to 3 months for alcohol and drugs. Hair samples are easy to collect, relatively resistant to tampering, and simple to transport.

A sample measuring 1.5 inches with roughly 200 strands (akin to the size of a #2 pencil) closest to the scalp yields 100mg of hair, which is optimal for screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, a 150mg specimen is advised. It is recommended to measure the specimen on a jeweler’s scale. If scalp hair is absent, an equivalent volume of body hair can be used. Head hair specifically refers to scalp hair, while body hair includes all other types (facial, axillary, etc.).

Process Overview

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

Accessioning entails the initial integration of a sample into a lab’s system, involving sealing and shipping verification, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data not captured by an electronic chain of custody.

Screening provides a quick initial check for drug abuse. Although cost-effective for excluding drug use in most samples, a positive screen must be confirmed to be valid in legal contexts. Presumptively positive samples in Screening require secondary confirmation.

Should a sample be presumptively positive in Screening, additional hair is extracted from the original specimen for Extraction. Here, drugs are extracted at a concentration lower than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Confirming any positive screening outcome is achieved via GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. The full laboratory process, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection period: Hair drug tests can reveal drug use up to 90 days, unlike urine tests which offer a shorter period.
• Hard to falsify: Cheating a hair drug test is challenging, ensuring more accurate outcomes.
• Historical data provision: It depicts a drug usage pattern over time, not solely recent use.

Limitations:

• No detection of recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests generally cost more than alternative methods.
• Result variations: Influenced by factors like hair color and individual growth rate affecting drug metabolite concentration.

Note: Although commonly labeled as "hair follicle tests", the analysis focuses on the hair strand, not the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Enka, NC, hair follicle testing surpasses urine testing due to its superior detection capabilities. Unlike urine tests, hair follicle testing can identify drug use over a longer period, offering unmatched reliability.
