Hair Follicle Drug Testing - Provencal, LA

What it is, How it works

Hair examinations serve as an effective approach for identifying alcohol and drug consumption. Hair offers a prolonged timeline of drug and alcohol usage by embedding biomarkers within the fibers of the growing hair strand. Once collected near the scalp, hair presents up to a roughly 3-month discovery period for drugs and alcohol. Hair is straightforward to collect, somewhat resistant to tampering, and convenient to transport.

Gathering a 1.5-inch sample consisting of roughly 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp provides a 100mg hair sample, which is optimal for analysis and verification. For EtG, additional testing, and/or panels exceeding ten, a 150mg sample is advised. It's best to measure the sample using a jeweler's scale. If scalp hair isn’t available, a proportional amount of body hair can be gathered. When referencing head hair, it pertains solely to scalp hair, while body hair includes all other types (such as facial or axillary hair).

Process Overview

The primary stages in the laboratory processing of drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.

Accessioning handles the initial integration of a sample into the laboratory’s system. This process encompasses confirming that the sample was sealed and dispatched accurately, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplemental data input not supplied by an electronic chain of custody framework.

Screening is a preliminary rapid examination for drugs typically abused. Although Screening is an economical method to rule out drug usage in most samples, a positive screen must be verified for court admissibility. Samples that yield presumptive positive results in Screening need further confirmation.

When a sample shows a presumptive positive in the Screening phase, additional hair is taken from the initial sample for preparation for Extraction. During Extraction, drugs are drawn out from hair at significantly lower concentrations compared to other methods (like urine or oral fluid), resulting in hair drug testing being one of the most complex methodologies.

Verification of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo washing as necessary before confirmation. The complete laboratory workflow from Accessioning to Confirmation is reviewed complying with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can perceive drug usage for as long as 90 days, unlike urine tests, which have a narrower detection timeframe.
• Challenging to deceive: Hair drug tests are difficult to circumvent, leading to more dependable outcomes.
• Offers historical insight: It can display a timeline of drug use rather than just recent usage.

Limitations:

• No detection of recent use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests typically incur higher costs compared to alternative drug testing methods.
• Result variability: Elements such as hair color and individual disparities in hair growth can influence drug metabolite concentration in hair.

Note: Although sometimes termed "hair follicle tests," the examination evaluates the hair strand, not the follicle beneath the scalp.
