Hair Follicle Drug Testing - Waterproof, LA

What it is, How it works

Hair analysis has emerged as a potent method for the identification of both drug and alcohol consumption. By embedding biomarkers within the fibers of growing hair strands, hair offers a prolonged record of drug and alcohol intake. When procured close to the scalp, hair can reveal drug and alcohol usage for up to around three months. This method is easy to conduct, relatively resistant to tampering, and straightforward to transport.

An ideal sample for testing and verification consists of a 1.5-inch segment of approximately 200 hair strands (about the thickness of a #2 pencil) taken closest to the scalp, yielding 100mg of hair. For EtG, additional testing, and panels beyond 10, a 150mg sample is advisable. We suggest determining the specimen's weight using a jeweler’s scale. If scalp hair cannot be obtained, a similar quantity of body hair can be collected. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The core stages involved in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into the lab’s system. This phase involves ensuring the sample was properly sealed and delivered, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry not covered by an electronic chain of custody system.

Screening serves as an initial swift evaluation for substance abuse. Although Screening is an economical method to dismiss drug presence in most samples, any positive findings require confirmation to be valid in legal scenarios. Samples identified as presumptively positive during Screening necessitate further verification.

In instances where a sample shows a presumptive positive in Screening, more hair is extracted from the original sample and prepped for Extraction. During this phase, drugs are isolated from hair at substantially lower concentrations than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening compared to other techniques.

Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleansed before confirmation if necessary. The entire lab process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair analyses can identify drug usage for up to 90 days, whereas urine tests offer a shorter detection duration.
• Challenging to compromise: Hair drug tests are hard to cheat, enhancing result reliability.
• Tracks drug usage patterns: It presents a record of drug consumption over time, rather than just recent usage.

Limitations:

• Incapable of detecting recent usage: Drugs become detectable in hair approximately 5-7 days following intake.
• Expense: Generally, hair drug tests are more costly than alternative drug testing methods.
• Result variability: Elements such as hair color and individual hair growth variations can influence drug metabolite concentrations in hair.

Note: Although commonly termed "hair follicle tests," the procedure scrutinizes the hair strand rather than the follicle beneath the scalp.
