Hair Follicle Drug Testing - Roanoke, LA

What it is, How it works

Hair analysis has emerged as an influential method for uncovering drug and alcohol consumption. The hair's fibers capture biomarkers as the hair grows, creating a prolonged record of substance use. When collected near the scalp, hair can offer up to roughly a 3-month potential detection period for alcohol and drugs. Hair is straightforward to gather, relatively hard to tamper with, and simple to transport.

A sample measuring 1.5 inches with around 200 hair strands (comparable to a #2 pencil's width) nearest the scalp will weigh 100mg, which is the optimal amount for assessing and confirming. For EtG, supplementary tests, and/or tests exceeding 10 panels, 150mg is advisable. We suggest using a jeweler’s scale for weighing the sample. If head hair isn't accessible, an equivalent quantity of body hair may be collected. When mentioning head hair, we refer to scalp hair only. Body hair includes all other hair (facial, axillary, etc.).

Process Overview

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

Accessioning signifies the preliminary handling of a sample into a lab's system. This process validates that the sample is sealed and dispatched correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry absent from an electronic chain of custody system.

Screening provides an initial quick assessment for drugs. Though cost-effective for ruling out drug use in most samples, a positive result in Screening must be confirmed for legal acceptance. Any samples that appear positive in Screening necessitate additional confirmation.

Should a sample appear positive during Screening, additional hair is extracted from the original sample for Extraction. Here, drugs are isolated from hair at significantly reduced concentrations compared to other methods (e.g., urine or saliva), making hair drug testing the most challenging method to conduct.

Confirmation of any positive result from Screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All potentially positive samples undergo washing before confirmation if necessary. The entire procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests have the capability to identify drug use for up to 90 days, unlike urine tests which present a shorter timeframe.
• Hard to deceive: It's exceedingly difficult to alter a hair drug test, rendering the findings more reliable.
• Delivers historical insight: It offers insights into a person's drug use pattern over time, rather than merely recent consumption.

Limitations:

• Cannot identify recent consumption: A timeframe of roughly 5-7 days is needed for drugs to register in hair.
• Expense: Hair drug tests usually cost more than other testing approaches.
• Result variations: Hair color and unique individual hair growth rates can influence the drug metabolite concentration in the hair.

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