Offering thorough hair follicle drug testing services in Purcellville, Virginia, Accredited Drug Testing shines in the field. If you're in need of a hair drug or alcohol examination, we excel in providing such analyses, with centers in cities across the nation conducting these tests. Typically, 1.5 to 2 inches of hair, whether from the head or body, is required. These tests can detect drugs, alcohol, ETG, or can be customized for other hair testing needs.
The trend in drug testing methodologies has increasingly leaned towards hair follicle analyses. Employers, judicial bodies, and substance abuse experts now favor these over the conventional urine tests. Used by organizations with strict drug policies, courts, and individuals on probation, the major advantage of hair follicle tests is their ability to detect drug use over a prolonged period, approximately 90 days, making it highly effective and hard to manipulate. However, urine tests remain superior for detecting recent drug use within 5 days.

Hair testing has evolved into a vital method for identifying drug and alcohol consumption. By capturing biomarkers within the hair's growing fibers, hair gives a prolonged history of alcohol and drug usage. When collected near the scalp, hair can indicate up to an estimated three-month window for detecting alcohol and drugs. This type of sampling is easy to collect, relatively hard to tamper with, and convenient to transport.
A 1.5-inch segment of roughly 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, the preferred sample size for screening and validation. For EtG, additional tests, and/or panels exceeding 10, acquiring 150mg is advised. We suggest using a jeweler's scale to weigh the sample. If scalp hair cannot be obtained, an equivalent amount of body hair is suitable. When mentioning head hair, we refer specifically to scalp hair. Body hair includes all other varieties (facial, axillary, etc.).
Process Overview
The laboratory drug testing process consists of four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step, where the sample is integrated into a laboratory's system. This includes confirming the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not managed by an electronic chain of custody system.
Screening serves as a preliminary swift assessment for substances of abuse. While Screening efficiently determines drug use in most samples, any positive screenings require further validation to be court-admissible. Any samples found presumptively positive in Screening necessitate secondary confirmation.
When a sample tests presumptively positive during Screening, additional hair is extracted from the original specimen for the Extraction process. During Extraction, drugs are removed from hair at a much lower concentration than with other techniques (e.g., urine or oral fluid), which makes hair drug screening notably challenging.
Validation of any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The comprehensive lab process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
