Hair Follicle Drug Testing - Pearson, WI

What it is, How it works

Hair analysis is increasingly recognized as a potent method for uncovering drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug intake by embedding biomarkers within the fibers of the developing hair strand. When trimmed near the scalp, hair can provide an estimated 3-month detection period for alcohol and drugs. Collecting hair is straightforward, relatively hard to tamper with, and convenient for shipping.

A sample measuring 1.5 inches with about 200 hair strands (approximately the girth of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is an optimal sample for testing and validation. For EtG, additional tests, and/or those over 10 panels, a 150mg specimen is preferable. It's suggested to weigh the specimen using a jeweler's scale. If scalp hair isn't accessible, an equivalent amount of body hair can be taken. When mentioning head hair, it specifically means scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).

Procedure Outline

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

Accessioning entails starting the integration of a sample into a laboratory's system. This process ensures the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data entry not included by an electronic chain of custody.

Screening involves a prompt initial evaluation for drugs of abuse. Although Screening is an affordable way to exclude drug usage in most samples, a verified screen is required for court admissibility. Presumptive positive samples from Screening need subsequent confirmation.

If the Screening phase yields a presumptive positive, additional hair from the initial sample is extracted to prepare for Extraction. During this phase, drugs are removed from hair at a significantly lower concentration than in other techniques like urine or oral fluid, making hair drug analysis the most challenging method to conduct.

Confirmation of positive screening results is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo cleaning before confirmation if required. The entire lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Benefits of hair drug analysis:

• Extended detection period: Hair drug analyses can identify drug usage for up to 90 days, whereas urine analyses have a shorter detection timeframe.
• Hard to manipulate: It is exceedingly challenging to deceive a hair drug analysis, enhancing result accuracy.
• Offers historical insight: It can disclose a pattern of drug consumption over time, not just recent usage.

Drawbacks:

• Inability to identify recent usage: Approximately 5-7 days are needed for drugs to become noticeable in hair.
• Expense: Hair drug analyses typically cost more than other drug testing approaches.
• Result variability: Aspects such as hair color and personal differences in hair growth can influence drug metabolite levels in hair.

Note: Although commonly called "hair follicle analyses", the test examines the hair strand instead of the follicle below the scalp.
