Hair Follicle Drug Testing - Wellfleet, NE

What it is, How it works

Hair analysis has evolved into a significant technique for identifying drug and alcohol consumption. Hair acts as a record of alcohol and drug consumption over an extended period by embedding biomarkers within the strands as they grow. By obtaining a sample near the scalp, a detection timeframe of around three months can be achieved for both alcohol and various drugs. Collecting hair is effortless, not easily tampered with, and straightforward to transport.

An ideal sample for evaluation and confirmation is a 1.5-inch segment comprising about 200 hair strands (similar in size to a #2 pencil), yielding 100mg of hair. For EtG, additional requirements, and/or tests exceeding 10 panels, a sample of 150mg is advisable. Using a jeweler's scale is recommended to weigh the sample. Should scalp hair be unavailable, an equivalent quantity of body hair may be taken. Reference to head hair specifically means scalp hair alone. Body hair encapsulates all other varieties (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning concerns the initial assimilation of a sample into a lab’s database. This step includes ensuring the sample’s sealing and shipment were correct, assigning a random LAN (Laboratory Accessioning Number), and entering any additional data not covered by an electronic chain of custody.

Screening incorporates an initial rapid examination for substance abuse. Though Screening is a budget-friendly means to exclude drug usage in most samples, a positive screen must be verified to stand in court. Any samples presenting a presumptive positive result in Screening necessitate secondary confirmation.

Should a sample yield a presumptive positive during the Screening phase, more hair is drawn from the primary sample and set for Extraction. In this phase, drugs are drawn from hair at lower concentrations compared to other methods (e.g., urine or saliva), signifying hair drug analysis is the most complex methodology to execute.

Each positive screening outcome undergoes Confirmation via GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positive results are cleaned before confirmation if necessary. The comprehensive laboratory workflow from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and meets ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can identify drug consumption up to 90 days, in contrast to urine evaluations which offer a briefer period.
• Challenging to falsify: Falsifying a hair drug test is particularly arduous, enhancing result accuracy.
• Offers historical insight: It uncovers a usage trend over time, rather than merely recent usage.

Limitations:

• Incapable of detecting recent intake: Detectability of drugs in hair requires about 5-7 days.
• Expense: Hair drug evaluations typically cost more than alternative methods.
• Result variability: Elements like hair color and individual growth variations can alter drug metabolite levels in hair.

Note: Although often termed as "hair follicle tests", the analysis itself is conducted on the strand and not the follicle beneath the scalp
