Accredited Drug Testing offers comprehensive hair follicle drug assessments in Lignum, Virginia. For those requiring hair drug or alcohol evaluations, Accredited Drug Testing excels in hair testing, with locations across the country to assist. Typically, 1.5 to 2 inches of hair from the crown or body is needed. These analyses cover drugs, alcohol/ETG, and other specialized hair testing needs.
Over recent years, drug testing methodologies have significantly shifted towards hair follicle assessments. Employers, courts, and substance abuse experts favor hair tests over traditional urine analyses. Hair tests are preferred by employers with zero-tolerance policies, judicial systems, and probation individuals. The key advantage is its ability to detect drug use up to 90 days, conducted with direct supervision, making it hard to circumvent. However, urine tests remain precise for recent drug consumption within the past five days.

Hair analysis has emerged as a significant instrument for identifying drug and alcohol consumption. Hair retains a prolonged history of alcohol and various drugs by embedding biomarkers within the fibers of the hair strand as it grows. When collected near the scalp, hair can offer up to a roughly 3-month detection range for alcohol and other drugs. Hair is straightforward to collect, somewhat challenging to tamper with, and convenient for shipping.
A hair sample of 1.5 inches containing about 200 strands of hair (around the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, the preferred quantity for screening and confirmation. For EtG, add-ons, and/or assessments exceeding 10 panels, 150mg of the specimen is advised. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair is not accessible, an equivalent amount of body hair may be collected. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The primary steps in the laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial handling of a sample within a laboratory's system. This process includes ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry not covered by an electronic chain of custody system.
Screening entails a preliminary check for drug misuse. Although Screening is a cost-effective approach to exclude drug usage in the bulk of samples, a positive screen must be verified to be admissible in court. Samples that are presumptively positive during Screening require a secondary confirmation.
When a sample is presumptively positive in the Screening phase, additional hair is extracted from the initial specimen and prepared for Extraction. During this phase, drugs are extracted from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging technique to perform.
Confirmation of any positive Screening result is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.

Note: Though commonly termed "hair follicle tests", the analysis actually examines the hair strand and not the follicle beneath the scalp.
