Hair Follicle Drug Testing - Leming, TX

What it is, How it works

Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers over time, offering a comprehensive record of alcohol and drug use. When taken near the scalp, hair samples can indicate usage of alcohol and substances for up to roughly a three-month period. Collecting hair is straightforward, relatively tough to tamper with, and conveniently transportable.

A hair sample measuring 1.5 inches, consisting of approximately 200 strands (similar in diameter to a #2 pencil), yields 100mg of hair, which is optimal for both screening and confirmation. For EtG, supplementary tests, and/or screens exceeding 10 panels, 150mg of the sample is suggested. It's advisable to weigh the sample with a jeweler’s scale. In cases where scalp hair is not available, an equivalent quantity of body hair can be obtained. References to head hair pertain solely to scalp hair, whereas body hair denotes all other types (facial, axillary, etc.).

Process Overview

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

Accessioning comprises the initial handling of a sample within a laboratory's framework. This phase includes ensuring the sample's proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing any absent data entry that is not covered by an electronic chain of custody system.

Screening functions as a preliminary assessment for illicit substances. Although Screening offers a cost-efficient method to eliminate drug presence in most samples, any positive result demands further confirmation to hold up legally. Presumptively positive samples identified in Screening necessitate additional validation.

For samples deemed presumptively positive during Screening, more hair is extracted from the initial collection and prepared for Extraction. During this phase, substances are extracted from hair at much lower concentrations compared to other techniques (e.g., urine or saliva), making hair drug testing one of the most intricate methodologies.

GC/MS, GC/MS/MS, or LC/MS/MS are employed to confirm any positive Screening results. Presumptive positive samples are cleansed as necessary prior to Confirmation. The comprehensive lab process, from Accessioning to Confirmation, undergoes inspection under both the CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug consumption over a 90-day span, whereas urine tests cover a shorter period.
• Resistance to cheating: Manipulating a hair drug test is notably challenging, thus ensuring greater result accuracy.
• Offers trend details: Hair tests can illustrate a pattern of drug consumption over time, beyond recent use.

Limitations:

• Delayed detection of recent use: Drugs typically become detectable in hair after 5-7 days.
• Expense: Hair drug screenings generally incur higher costs relative to other testing methods.
• Fluctuating outcomes: Elements like hair color and individual growth rates can influence metabolite concentrations.

Note: Commonly termed "hair follicle tests," these assessments actually analyze the hair strand itself, not the underlying follicle.
