Hair Follicle Drug Testing - Brusly, LA

What it is, How it works

Hair testing is now recognized as a robust method for identifying drug and alcohol usage. Hair captures a prolonged timeline of alcohol and other drugs by embedding biomarkers within its growing fiber strands. Collected nearby the scalp, hair can furnish an approximate 3-month window for detecting alcohol and various drugs. Hair is easy to gather, hard to tamper, and convenient to transfer.

A hair sample of 1.5 inches in length consisting of about 200 strands (comparable to a #2 pencil) taken closest to the scalp will yield 100mg of hair, serving as the perfect specimen for screening and validation. For EtG, additional, and/or more than 10-panel tests, 150mg of the sample is advised. Utilizing a jeweler’s scale is suggested to weigh the specimen. If scalp hair is inaccessible, an equal volume of body hair can be utilized. By head hair, we mean scalp hair solely. Body hair refers to all other types of hair (facial, axillary, etc.).

Process Overview

The laboratory process for deriving a drug test outcome consists of four essential stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the primary processing of a specimen within a laboratory’s system. This process entails confirming the proper sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any extra data entry not encompassed by an electronic chain of custody system.

Screening involves an immediate preliminary assessment for substance misuse. Although Screening is a cost-efficient approach to eliminate drug usage in most samples, a positive screening demands confirmation to be acceptable in legal scenarios. Samples preliminarily positive in the Screening stage require additional confirmation.

For a sample deemed positive in Screening, more hair is extracted from the original specimen for preparation in the Extraction phase. Here, drugs are extracted from hair at concentrations significantly lower than in other techniques (such as urine or oral fluid), highlighting the complexity of performing hair drug testing.

Confirmation of any Screening positive outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Pre-confirmation, all presumptive positive samples undergo washing if necessary. The complete laboratory process from Accessioning through Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair certification and compliance with ISO / IEC 17025 standards.

Benefits of hair-based drug testing:

• Extended detection period: Hair drug assays can recognize drug consumption for up to 90 days, unlike urine tests with a narrower detection span.
• Hard to manipulate: Altering a hair drug test is extremely challenging, enhancing result accuracy.
• Offers historical data: It reveals a pattern of drug intake over time, covering more than just immediate use.

Constraints:

• Non-detection of recent use: Drugs become detectable in hair roughly around 5-7 days post-use.
• Expense: Generally, hair drug assessments incur higher costs than other testing methods.
• Result variability: Factors like hair color and individual hair growth variations can influence drug metabolite concentrations within the hair.

Note: Commonly termed as "hair follicle tests", the analysis targets the hair strand itself rather than the follicle beneath the scalp.
