Hair Follicle Drug Testing - Wingate, NC

What it is, How it works

The recognition of hair testing as a significant technique for identifying drug and alcohol use has grown. Hair captures a comprehensive history of alcohol and other substance use by embedding biomarkers within its growing strands. When procured from near the scalp, hair may reveal drug and alcohol usage over an approximate three-month period. Hair collection is straightforward, hard to tamper with, and easy to transport.

A sample measuring 1.5 inches with around 200 strands (comparable to a #2 pencil in width) from the scalp yields 100mg of hair, the optimal sample size for screening and validation. For EtG, additional tests, and panels exceeding ten, a specimen of 150mg is advisable. Utilizing a jeweler's scale for weighing the specimen is suggested. If scalp hair is absent, a similar amount of body hair might be used. References to head hair imply scalp hair exclusively, while body hair encompasses all other types like facial or axillary hair.

Process Overview

The core phases in a lab's handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning manages the preliminary processing of a sample within a lab's framework. This step ensures the sample is correctly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any remaining data entry not covered by an electronic custody control system.

Screening performs an initial swift assessment for drug presence. While Screening is cost-efficient for eliminating drug use in most samples, positive findings must be verified to stand in legal situations. Samples with presumptive positives from Screening need subsequent verification.

In cases where Screening results indicate a presumptive positive, additional hair is extracted from the original specimen for the Extraction stage. Here, drugs are removed from hair at significantly lower levels than other methods like urine or oral fluid, making hair screening particularly challenging.

Verification of a positive screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positives are cleaned before confirmation as required. Each step, from Accessioning through Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair standard and the ISO / IEC 17025 accreditation criteria.

Pros of hair drug testing:

• Extended detection range: Hair tests can trace drug use up to 90 days, unlike urine tests with shorter detection periods.
• Hard to deceive: Tampering with hair drug tests is notably challenging, ensuring more reliable outcomes.
• Offers usage history: It reveals patterns of drug use over time, not just recent consumption.

Drawbacks:

• Unable to detect recent consumption: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests are typically pricier than other testing approaches.
• Inconsistent results: Elements like hair color and personal differences in hair growth can influence drug metabolite levels in hair.

Note: Commonly called "hair follicle tests", the analysis focuses on the hair strand rather than the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
