Hair Follicle Drug Testing - Rock Hall, MD

What it is, How it works

Hair testing has become recognized as an effective means for identifying drug and alcohol consumption. Hair retains a comprehensive record of alcohol and drug use by encapsulating biomarkers within the growing strands. When sampled near the scalp, this method can offer an approximate 90-day detection span for alcohol and drugs. Collecting hair is straightforward, resistant to tampering, and convenient to transport.

A sample size of 1.5 inches consisting of around 200 hair strands (comparable to a #2 pencil's width) nearest the scalp provides 100mg, which is perfect for both screening and validation. For EtG, add-ons, and panels exceeding 10 panels, it's advisable to use a 150mg specimen. Using a jeweler’s scale for accurate measurement is suggested. Should scalp hair be unavailable, collecting an equivalent amount of body hair is an alternative. It’s important to specify that head hair pertains to scalp hair, whereas body hair includes all other varieties (such as facial and axillary hair).

Process Overview

The lab-based drug testing process encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial handling of a sample in a lab system. This involves confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any required data entry omitted by an electronic chain of custody system.

Screening presents a preliminary evaluation for drugs of abuse. Though Screening is an economical method to dismiss drug usage in most samples, a positive screen necessitates confirmation for legal admissibility. Any samples with a positive outcome in Screening need further validation.

If a sample returns a presumptive positive during Screening, additional hair is extracted from the initial sample for the Extraction stage. In this phase, drugs are extracted from hair at notably lower levels compared to other methods (such as urine or oral fluid); hence, hair drug testing is particularly challenging to conduct.

Confirming any positive screening outcomes is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All samples flagged as presumptively positive are cleansed before confirmation, if required. The entire lab procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection timeframe.
• Hard to falsify: It's exceedingly challenging to deceive a hair drug test, enhancing result reliability.
• Offers historical insights: It delivers a drug usage pattern over time, not solely recent consumption.

Limitations:

• Inability to detect recent use: It requires around 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug tests typically cost more than other drug testing methodologies.
• Result variations: Elements such as hair color and individual hair growth differences can impact drug metabolite concentration in hair.

Note: Although commonly termed "hair follicle tests", these tests examine hair strands and not follicles beneath the scalp.
