Hair Follicle Drug Testing - Centreville, VA

What it is, How it works

Hair testing is now regarded as an efficient method for uncovering drug and alcohol consumption. Hair offers an extended timeline of such use by embedding biomarkers within the fibers of the developing hair strand. When clipped near the scalp, it serves as a detection tool for up to around a 3-month window for both alcohol and other narcotics. Hair is effortless to gather, somewhat resistant to tampering, and straightforward to transport.

Cutting a 1.5-inch segment of roughly 200 hair strands (akin to the thickness of a #2 pencil) nearest to the scalp produces 100mg of hair, which is deemed the optimal amount for analysis and confirmation. For EtG, ancillary tests, or tests exceeding 10 panels, a specimen of 150mg is suggested. It is advisable to measure the specimen with a jeweler’s balance. Should scalp hair not be available, a proportional quantity of body hair can be utilized. By head hair, we denote solely to scalp hair. Body hair constitutes all extra hair types (e.g., facial, axillary, etc.).

Process Overview

The laboratory handling of a drug test outcome incorporates four crucial stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the primary incorporation of a sample into a lab’s framework. This process ensures the sample’s proper sealing and transportation, allocates a random LAN (Laboratory Accessioning Number), and seeks completion of any additional data recording absent in an electronic chain of custody system.

Screening implies a rapid assessment for drugs commonly misused. Although Screening provides a cost-saving approach to negate drug presence in the majority of samples, any positive findings in Screening necessitate confirmation to hold up legally. Any samples flagged as positive in Screening must undergo secondary confirmation.

Should a sample yield a positive hint during Screening, further hair is extracted from the initiate for Extraction preparation. Here, drug traces are extracted at much lower concentrations compared to alternative methods (e.g., urine or oral fluid), establishing hair drug Screening as the most complex of methodologies.

Any affirmed positive findings in Screening undergo Confirmation through pathways such as GC/MS, GC/MS/MS or LC/MS/MS. Every presumptive positive specimen is cleansed ahead of confirmation when deemed essential. The full laboratory procedure from Accessioning to Confirmation is scrutinized according to both the CAP (College of American Pathologists) Hair standard and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection range: Hair drug screenings can identify drug usage for up to 90 days, juxtaposed with urine assessments which offer a more limited detection span.
• Minimized risk of manipulation: Hair drug tests are notably difficult to falsify, enhancing result credibility.
• Tracks historical usage: It can outline a sequence of drug use over time, rather than just recent exposure.

Limitations:

• Incapable of recognizing recent activity: Drugs require approximately 5-7 days to become detectable in hair.
• Expense: Hair drug tests typically incur higher costs than other drug testing techniques.
• Result discrepancies: Variables such as hair color and personal growth differences can influence the level of drug metabolites in the hair.

Note: Although commonly referred to as "hair follicle tests", the assessment concerns the hair strands, bypassing the follicle beneath the scalp.
