Hair Follicle Drug Testing - Smiths, AL

What it is, How it works

Hair analysis has gained recognition as a potent means for uncovering drug and alcohol consumption. Hair archives long-standing evidence of alcohol and drug intake by embedding markers in its growing fibers. When sourced near the scalp, hair can reveal alcohol and drug use for up to approximately 90 days. Collecting hair is straightforward, relatively tamper-resistant, and easy to transport.

A 1.5-inch segment of about 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal quantity for both screening and verifying results. For EtG, add-ons, or tests exceeding 10 panels, a 150mg sample is advised. It's suggested to weigh the specimen on a jeweler's scale. If scalp hair is inaccessible, an equal volume of body hair may be utilized. By "head hair," we refer exclusively to scalp hair. "Body hair" encompasses all other types (e.g., facial, axillary).

Process Overview

The laboratory handling of a drug test outcome involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary integration of a sample into a lab's system. This process checks that the sample was sealed and dispatched correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any data entry missing from an electronic chain of custody system.

Screening serves as an initial rapid assessment for the presence of drugs. Although Screening is an affordable method to dismiss drug use in most samples, a positive screen must be confirmed before court admittance. Samples that register as presumptively positive during Screening do require a secondary confirmation.

If a sample is flagged as presumptively positive during Screening, additional hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are derived from hair at notably reduced concentrations compared to other methods (e.g., urine or oral fluid), hence hair drug screening is the most arduous methodology to execute.

Confirmation of any positive screen is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation as required. The comprehensive laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair categorization and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can identify drug use for up to 90 days, in contrast to urine tests which possess a narrower detection span.
• Hard to bypass: Evading a hair drug assessment is exceedingly difficult, resulting in more precise outcomes.
• Offers historical insight: It reveals a consumption pattern over time, not just recent intake.

Limitations:

• Incapable of detecting recent intake: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug assessments tend to be pricier than alternative drug testing techniques.
• Result variability: Elements such as hair color and personal hair growth discrepancies can influence drug metabolite concentrations in hair.

Note: Although frequently termed "hair follicle tests", the examination analyzes the hair strand itself, not the follicle beneath the scalp
