Hair Follicle Drug Testing - Crewe, VA

What it is, How it works

Through growing acceptance, hair testing has become an influential method for identifying drug and alcohol consumption. By capturing biomarkers within the strands of developing hair, it offers a comprehensive timeline of substance use. When sourced near the scalp, hair offers roughly a 3-month period during which alcohol and drug usage can be detected. Collection is straightforward, tampering is challenging, and transport is uncomplicated.

Securing a 1.5-inch segment of approximately 200 hair strands (comparable to the girth of a #2 pencil) nearest to the scalp, amounts to 100mg of hair, the prime sample size for both screening and confirmation. For EtG, additional tests, and/or examinations exceeding 10 panels, a 150mg sample is advocated. We advise measuring the sample on a jeweler's scale. Should scalp hair be inaccessible, an equal quantity of body hair can be gathered. "Head hair" pertains to scalp hair specifically. "Body hair" denotes any other hair types (facial, axillary, etc.).

Process Summary

In the lab analysis of a drug test result, the key stages are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary integration of a sample into a lab's framework. This step consists of verifying proper sealing and shipment of the sample, assigning an arbitrary LAN (Laboratory Accessioning Number), and inputting any supplementary data not captured by an electronic chain of custody system.

Screening serves as an initial rapid assessment for drugs of abuse. While Screening economically excludes drug use in most samples, any positive findings must be substantiated to hold up in legal proceedings. Samples that yield presumptive positives during Screening require confirmation through additional testing.

Should a sample yield a presumptive positive during Screening, more hair is extracted from the initial sample and readied for Extraction. At this phase, drug extraction from hair occurs at notably lower concentrations compared to other means (ex. urine or oral fluid), illustrating why hair drug testing is exceptionally complex.

Confirmation of any positive screening outcome is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to Confirmation, presumptive positive samples are washed as necessary. A complete review from Accessioning to Confirmation takes place under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Benefits of hair drug screening include:

• Extended detection period: Hair drug screenings can identify drug usage for up to 90 days, contrasting with urine tests which have shorter detection spans.
• Challenging to evade: Hair drug testing proves challenging to tamper with, resulting in greater accuracy in outcomes.
• Offers usage history: It reveals patterns of drug consumption over extended durations, not solely recent use.

Drawbacks:

• Incapable of detecting recent usage: Detecting drugs in hair requires approximately 5-7 days.
• Expense: Hair drug testing typically incurs higher costs than alternative testing techniques.
• Result variability: Elements like hair color and individual hair growth differences can influence drug metabolite levels in hair.

Clarification: Though often termed “hair follicle tests,” the analysis targets the hair strand itself instead of the follicle beneath the scalp.
