Hair Follicle Drug Testing - Hallwood, VA

What it is, How it works

Hair analysis has gained recognition as an effective means for identifying drug and alcohol consumption. Hair retains a long-term record of these substances by encapsulating biomarkers within its fibers. When procured near the scalp, the sample can indicate a history of up to three months regarding alcohol and drug presence. Collecting hair is straightforward, resistant to tampering, and convenient for transportation.

A 1.5-inch hair sample consisting of roughly 200 strands, comparable to the thickness of a #2 pencil, will yield 100mg, which is optimal for screenings and confirmations. For EtG, additional tests, and/or panels exceeding ten, a specimen of 150mg is advisable. We suggest measuring the specimen with a jewelry scale. In the absence of scalp hair, an equivalent amount from body hair can be gathered. Reference to head hair pertains only to scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory process of determining a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage of integrating a sample into a lab's system, involving the verification of proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and concluding any additional data entry overlooked by an electronic chain of custody system.

Screening is an initial assessment for drugs. Although it provides a budget-friendly method to dismiss drug presence in most samples, any positive findings must be affirmed for legal purposes. Samples with presumptive positive readings during Screening necessitate further verification.

Presumptive positive samples require more hair to be extracted for further analysis. During Extraction, drugs are retrieved from hair at lower concentrations than other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug testing.

Confirmation of positive screening results is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivism undergo washing before the confirmation stage. The entire laboratory procedure from Accessioning to Confirmation is conducted following the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can track drug use for up to 90 days, unlike urine tests that cover shorter durations.
• Hard to adulterate: It is tough to tamper with a hair drug test, lending to more precise outcomes.
• Chronological data: It reveals drug consumption patterns over time, beyond mere recent use.

Limitations:

• Ineffectual for recent use: Drugs need approximately 5-7 days to be traceable in hair.
• Expense: Hair drug assessments are usually costlier than other testing methods.
• Result variation: Variables such as hair pigmentation and individual hair growth differences can impact drug metabolite levels in hair.

Note: Commonly known as "hair follicle tests", the method evaluates the hair strand itself, rather than the follicle beneath the scalp.
