Accredited Drug Testing provides extensive hair follicle drug testing services in Williamsville, Virginia. If you're in need of a hair or alcohol screening, Accredited Drug Testing is an expert in hair testing, with facilities in cities across the nation equipped to handle hair analyses. Typically, 1.5 to 2 inches of hair from the head or body is needed. Hair analyses can detect drugs, alcohol/ETG, or can be tailored for other specific testing needs.
Drug testing methods have increasingly involved hair follicle drug testing in recent times. A variety of employers, judicial entities, and substance abuse experts are now opting for hair tests instead of the traditional urine analysis. Hair follicle testing is preferred by employers enforcing strict no-drug policies, legal courts, and probation officers, primarily due to its extended detection timeframe of up to 90 days, making it nearly foolproof to circumvent. Yet, for identifying drug usage within the past five days, the urine test remains unmatched in accuracy.

The utilization of hair testing has emerged as a significant method in identifying drug and alcohol consumption. Hair serves as a long-term registry of alcohol and drug presence by embedding biomarkers within its fibers during growth. When gathered near the scalp, hair offers a detection window of roughly 3 months for alcohol and drugs. The collection process for hair is straightforward, relatively tamper-resistant, and convenient for transport.
A segment of 1.5 inches comprising approximately 200 hair strands (similar in diameter to a #2 pencil) near the scalp yields 100mg, which is optimal for analysis and verification. For EtG, additional screenings, and/or tests exceeding 10 panels, 150mg of hair is preferable. Measuring the sample using a jeweler’s scale is advised. Should scalp hair be absent, an equivalent quantity of body hair can be used. References to head hair exclusively denote scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four primary phases in the laboratory processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial incorporation of a sample into the lab’s framework. This stage encompasses ensuring the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any residual data input not facilitated by an electronic chain of custody protocol.
Screening acts as a preliminary assessment for drug presence. Though cost-effective, a positive result in Screening must undergo confirmation for legal validity. Samples yielding a presumptive positive from Screening require subsequent confirmation.
In instances of presumptive positives in Screening, more hair is extracted from the original sample for the Extraction phase. In this phase, drug components are isolated from hair at a concentration considerably lower than found in other methods (e.g., urine or saliva), underscoring hair drug testing’s complexity.
Confirmation of positive screening outcomes is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo cleansing before confirmation if needed. The complete lab procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair classification and complies with ISO / IEC 17025 standards.
