Hair Follicle Drug Testing - Fort Polk North, LA

What it is, How it works

Hair analysis has emerged as an effective method for detecting substance use, including drugs and alcohol. This technique offers an extended history of substance intake due to the entrapment of biomarkers within the hair's strands. A sample taken close to the scalp can reveal alcohol or drug intake over a period extending up to roughly three months. Hair sampling is straightforward to gather, relatively tamper-resistant, and straightforward to transport.

Gathering a 1.5-inch segment of approximately 200 hair strands (roughly matching the thickness of a standard #2 pencil) next to the scalp yields 100mg of hair, which is optimal for conducting both screening and confirming tests. For EtG, additional analyses, and/or screenings surpassing 10 panels, it’s advised to obtain 150mg of the hair sample. Using a jeweler’s scale for precise measurement is suggested. In cases where scalp hair is unavailable, a similar volume of body hair can be utilized. "Head hair" implies only scalp hair, whereas "body hair" encompasses all other types such as facial or underarm hair.

Process Overview

The processing of drug test results in a lab involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initiation of processing in a lab’s system, involving the validation of proper sample sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and finalizing any requisite data entry when not supplied by an electronic custody system.

Screening offers a preliminary scan for drug usage. Though this is a budget-friendly means to identify drug use in most samples, a positive screen necessitates confirmation for legal acceptability. Samples registering as presumptively positive during Screening need subsequent confirmation.

If a sample shows presumptive positivity at Screening, more hair is allocated from the original sample to prep for Extraction. During this, drugs are isolated from the hair at reduced concentrations compared to other techniques (e.g., urine or oral fluids), underscoring the precision required for hair drug testing.

Positive findings in screening undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Presumptive positive samples are cleansed before confirmation when necessary. The complete laboratory flow from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) designation and accords with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detectable period: Hair testing can observe drug use for up to 90 days, compared with the shorter span found in urine analyses.
• Enhanced test reliability: Manipulating a hair drug test is challenging, rendering outcomes more trustworthy.
• Usage trend insight: It discloses substance usage patterns over time, beyond immediate usage.

Limitations:

• Ineffective for recent intake: Drugs are typically identifiable in hair after 5 to 7 days.
• Higher expenditure: Hair testing incurs greater costs than alternative testing methods.
• Result variability: Aspects like hair pigmentation and personal growth variations may impact drug metabolite concentration within hair strands.

Note: Commonly known as "hair follicle tests", this examination actually assesses the hair strand itself, rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Fort Polk North, LA, hair follicle testing offers a significant advantage over urine testing. Its primary benefit lies in a much longer detection period for drug use, typically up to 90 days, which gives employers a better understanding of an individual's substance use history. This surpasses the limited window of a urine test, making hair tests more reliable for monitoring long-term abstinence.

The reliability of hair testing is heightened by its resistance to tampering, an issue often encountered with urine tests. With stringent collection protocols that ensure sample integrity, hair testing is far less susceptible to manipulation, providing accurate and trustworthy results that employers can depend on.
