Hair Follicle Drug Testing - Abingdon, VA

What it is, How it works

The examination of hair has emerged as a formidable method for identifying drug and alcohol consumption. Hair retains a prolonged chronicle of substance intake by embedding biomarkers within the strands as they grow. When procured near the scalp, hair can yield approximately a 90-day detection timeframe for intoxicants. Procuring hair is straightforward, challenging to tamper with, and convenient for dispatch.

A 1.5-inch segment comprising around 200 hair strands (akin to the thickness of a #2 pencil) nearest to the scalp will supply 100mg of hair, making it the perfect sample for both screening and confirmation. For EtG, supplementary tests, and/or assays exceeding 10 panels, a specimen of 150mg is advisable. Utilizing a jeweler’s scale for weighing the sample is suggested. In the absence of scalp hair, a comparable quantity of body hair can be gathered. When speaking of head hair, it pertains solely to scalp hair. Body hair denotes all other hair varieties (facial, axillary, etc.).

Step-by-Step Procedure

The laboratory procedure for handling a drug test outcome encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial phase of incorporating a sample into a lab’s framework. This includes ensuring the sample was appropriately sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and finalizing any additional record logging absent from an electronic chain of custody system.

Screening performs a preliminary swift evaluation for substance abuse. Though Screening is cost-efficient for discounting drug use on most samples, a positive screen needs verification for legal acceptability. Samples with implied positive results from Screening require further confirmation.

Should a sample return a presumptive positive at the Screening phase, more hair is sourced from the original specimen and prepped for Extraction. During this stage, drugs are extracted from hair at substantially lower concentrations compared to other techniques (e.g., urine or oral fluid), hence the complexity of hair drug screening.

The Confirmation process of any positive screening result employs GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives are cleansed as necessary before confirmation. The comprehensive laboratory workflow from Accessioning to Confirmation undergoes evaluation under CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can identify drug intake for as long as 90 days, unlike urine tests with limited detection spans.
• Minimized chance of deceit: Hair drug tests pose significant challenges against cheating, thereby ensuring more precise results.
• Chronological substance usage: It highlights a trend in drug usage over time, not just recent consumption.

Disadvantages:

• Inability to detect immediate use: It takes roughly 5-7 days for drugs to manifest in hair.
• Expensiveness: Hair drug assessments tend to be costlier than other testing techniques.
• Results variability: Attributes like hair shade and personal hair growth discrepancies can influence drug metabolite levels in the hair.

Note: Although commonly termed "hair follicle tests", the analysis concerns the hair strand itself, not the follicle beneath the scalp
