Hair Follicle Drug Testing - Rock Island, WA

What it is, How it works

Evaluated as highly effective, hair testing serves as a substantial method for identifying drug and alcohol consumption. With hair strands capturing biomarkers within their fibers, they offer a chronological archive of substances. When hair is collected near the scalp, it can reveal alcohol or drug use spanning up to three months. Collecting hair is straightforward, challenging to alter, and straightforward to transport.

A hair sample measuring 1.5 inches with approximately 200 strands (approximately equal to a #2 pencil) taken close to the scalp yields 100mg, which is optimal for testing and verification. For EtG, additional tests, or screenings beyond 10 panels, a specimen weighing 150mg is preferable. Using a jeweler’s scale for measurement is advised. In the absence of scalp hair, an equivalent quantity of body hair may be substituted. When mentioning head hair, it specifically pertains to scalp hair. All other hair types (such as facial and axillary) fall under body hair.

Process Overview

Drug test laboratory processing involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where a sample is incorporated into the lab’s workflow. It encompasses checking for correct sample sealing and shipping, generating a random LAN (Laboratory Accessioning Number), and completing additional data entry tasks not covered by an electronic chain of custody.

Screening provides a preliminary check for substance abuse. Though cost-effective for excluding the presence of drugs in most samples, a positive screening outcome must be confirmed for legal purposes. Samples that are presumptively positive require further confirmation.

If a sample indicates presumptive positivity during Screening, additional hair from the primary sample is utilized for Extraction. This phase involves extracting drugs from hair at a much lower concentration than in alternative methodologies (e.g., urine or oral fluid), resulting in hair drug screening being notably challenging.

Confirmation of any presumptive positive result is performed employing methods such as GC/MS, GC/MS/MS, or LC/MS/MS. Required washing of all presumptive positive samples occurs before confirmation. The comprehensive laboratory procedure from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair specification and accreditation to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can detect drug use for up to 90 days, a longer span compared to urine tests.
• Difficulty to cheat: The challenges in cheating a hair drug test render the results more reliable.
• Provides historical data: It offers insights into drug usage patterns over time, beyond just recent consumption.

Limitations:

• Cannot detect recent use: Drugs take about 5-7 days to become detectable in hair.
• Cost: Hair drug tests commonly exceed the cost of other drug testing techniques.
• Variations in results: Individual differences such as hair color and growth rate can influence the concentration of drug residues in hair.

Note: Although commonly called "hair follicle tests", the procedure examines the hair strand itself, not the follicle beneath the scalp.
