Hair Follicle Drug Testing - Leonville, LA

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. It offers a comprehensive history of substance use by embedding biomarkers within the hair fiber as it grows. When collected close to the scalp, hair can offer a detection period for alcohol and other drugs extending up to roughly three months. Collecting hair is straightforward, not easily tampered with, and convenient to transport.

A 1.5-inch segment of approximately 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a quantity of 150mg from the sample is advisable. We suggest using a jeweler’s scale for measuring the sample. In the absence of scalp hair, an equivalent amount of body hair may be gathered. Reference to head hair specifically implies scalp hair alone. Body hair pertains to all other types (facial, axillary, etc.).

Process Overview

The primary stages in the laboratory handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial processing of a sample into a laboratory’s system, which includes verifying that the sample was adequately sealed and shipped, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any supplemental data entry not supplied by an electronic chain of custody system.

Screening implies an initial quick assessment for illicit drugs. While Screening serves as an economical approach to dismiss drug usage in the majority of samples, a positive screen necessitates confirmation to be court-admissible. Any samples yielding presumptive positive results in Screening require a follow-up confirmation.

Should a sample test presumptively positive during Screening, additional hair is extracted from the original specimen and prepared for Extraction. In this phase, drugs are extracted from hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), which explains why hair drug testing is the most challenging method to conduct.

Confirmation of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptive positive undergo a washing process before confirmation as required. The whole laboratory process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, unlike urine tests with a shorter detection timeframe.
• Resilience to tampering: Cheating a hair drug test is very difficult, which enhances result accuracy.
• Offers historical insight: It can demonstrate a pattern of drug use across a duration, not merely recent use.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days post-use.
• Costly: Hair drug tests typically cost more than alternative drug testing methods.
• Result variations: Elements such as hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Commonly termed as "hair follicle tests", the analysis actually involves the hair strand, not the follicle beneath the scalp.
