Hair Follicle Drug Testing - Wann, NE

What it is, How it works

Hair analysis is now considered a formidable method for identifying drug and alcohol consumption. Hair offers an extended record of substance use by capturing biomarkers within the strands of emerging hair. Collected near the scalp, hair can yield a detection timeframe of up to roughly 90 days for alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and convenient for shipping.

A 1.5-inch segment of approximately 200 hair strands (equivalent to a #2 pencil in thickness) nearest the scalp provides 100mg of hair, an optimal sample for both screening and confirmation. For EtG, additional tests, or more than 10 panels, 150mg of hair is advised. It’s advisable to weigh the specimen with a jeweler’s scale. If scalp hair is not an option, the equivalent amount of body hair should be taken. When mentioning head hair, it exclusively concerns scalp hair. Body hair encompasses all other hair types (including facial and axillary).

Process Overview

The primary stages in the lab handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves integrating a sample into a lab’s database. This covers confirming the sample was correctly sealed and dispatched, generating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent in an electronic chain of custody.

Screening provides an initial assessment for drugs of abuse. While it's a cost-efficient measure to discount drug use in most samples, confirmation is required for any positive screening to be court-admissible. Samples showing presumptive positive results in Screening demand a secondary confirmation.

If Screening hints at a positive result, additional hair is drawn from the primary sample and readied for Extraction. Here, drugs are separated from hair at much lower concentrations compared to other techniques (e.g., urine or oral fluid), making hair drug screening a challenging methodology.

Verification of any positive Screening outcome uses GC/MS, GC/MS/MS or LC/MS/MS. All presumptively positive samples undergo washing before confirmation if needed. The complete laboratory operation from Accessioning to Confirmation undergoes a review under both the CAP (College of American Pathologists) Hair designation and meets ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests identify drug use spanning up to 90 days, unlike urine tests with shorter detection periods.
• Difficult to manipulate: Cheating on a hair drug test is highly challenging, making results more reliable.
• Offers historical insights: It demonstrates a pattern of drug use over time, rather than just recent usage.

Limitations:

• Inability to detect recent activity: Detectable drugs in hair appear after about 5-7 days.
• Expense: Hair drug tests typically cost more than alternative drug test methods.
• Result variability: Hair color and personal variations in hair growth can influence drug metabolite concentrations in hair.

Note: Although commonly called "hair follicle tests", the analysis targets the hair strand instead of the follicle beneath the scalp.
