Hair Follicle Drug Testing - Whittier, NC

What it is, How it works

The perception of hair testing has evolved into a vital technique for unveiling the history of alcohol and drug consumption. By embedding biomarkers within the hair's growing strands, it offers a comprehensive record of substance use. When clipped close to the scalp, hair samples can capture substance intake details up to an estimated three-month span. Hair collection is straightforward, tampering is challenging, and transportation is convenient.

Gathering a 1.5-inch segment containing roughly 200 hair strands (similar in thickness to a #2 pencil) from near the scalp yields 100mg, which is an optimal amount for both screening and verification. For more extensive tests like EtG add-ons or panels beyond 10, a 150mg specimen is advisable. We suggest using a jeweler’s scale for accuracy. Should scalp hair be unavailable, equivalent body hair is an acceptable substitute. In our context, "head hair" strictly denotes scalp hair, whereas "body hair" encompasses all other varieties (including facial and axillary).

Process Overview

The drug test result processing at labs involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning focuses on the preliminary sample inclusion in the lab's system. The procedure includes ensuring the sample's seal and shipment integrity, assigning a randomized LAN (Laboratory Accessioning Number), and finishing any supplementary data input not covered by an electronic chain of custody system.

Screening conducts an initial, swift assessment for signs of drug presence. Although cost-efficient for distinguishing drug negatives in most samples, any positive screening outcome necessitates official confirmation for legal validity. Samples with tentative positive results must undergo further confirmation.

Should a sample test preliminarily positive in the Screening phase, additional hair is extracted from the initial collection for further analysis during the Extraction stage. Here, drug components are isolated from the hair at notably lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair-based drug testing.

The Confirmation phase for affirming preliminary screening results employs techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples tentatively marked as positive undergo a washing procedure prior to confirmation, as necessary. The comprehensive workflow from Accessioning through Confirmation adheres to both CAP (College of American Pathologists) Hair classification and accreditation according to ISO / IEC 17025 norms.

Advantages of hair drug testing:

• Extended detection span: Hair drug assessments can reveal drug intake up to 90 days back, which is longer than the timeframe urine tests can account for.
• Resistance to tampering: Cheating on a hair drug test is notably challenging, thus boosting result fidelity.
• Reveals usage patterns: Offers an insight into long-term substance use trends, rather than just recent incidents.

Limitations:

• Not suitable for recent usage: Detection of drug residue in hair takes approximately 5-7 days to manifest.
• Cost considerations: Compared to other testing methods, hair drug assessments often come with higher expenses.
• Results variability: Variances such as hair pigmentation and individualized growth rates can influence metabolite concentration levels within the hair.

Note: Commonly called "hair follicle tests", the analysis is conducted on the hair strand itself, not the follicle beneath the scalp.
