Accredited Drug Testing offers comprehensive hair follicle drug analysis in Wytheville, Virginia. If a hair test for drugs or alcohol is needed, our expertise lies in hair analysis. Our centers are spread across all major cities nationwide. Usually, 1.5 to 2 inches of head or body hair can be tested. Tests can identify drugs, alcohol/ETG, or other tailored hair testing solutions.
Recently, drug testing increasingly involves hair follicle analysis. Employers, courts, and substance abuse professionals now often prefer hair tests over urine tests. Employers with strict anti-drug policies, along with courts and probation officers, favor this method. The biggest advantage of hair testing is its extended drug detection window, which is typically up to 90 days. Hair collection is observed, minimizing tampering. However, for substance use within the past five days, urine tests remain most accurate.

Hair testing is recognized as an effective means for identifying drug and alcohol consumption. Hair encapsulates a prolonged timeline of substance use by encasing biomarkers within the fibers of developing hair strands. When procured near the scalp, hair offers up to an approximate 3-month detection period for alcohol and drugs. Collection of hair is straightforward, relatively tamper-resistant, and convenient to transport.
A 1.5-inch sample, consisting of near 200 hair strands (around the diameter of a #2 pencil) closest to the scalp, provides 100mg of hair, an optimal amount for screening and confirmation. For EtG, specialized tests, and/or assessments that exceed 10 panels, a specimen of 150mg is suggested. It is advised to weigh the sample using a jeweler’s scale. In instances where scalp hair is not available, an equivalent quantity of body hair can be gathered. When mentioning head hair, it pertains strictly to scalp hair. Body hair refers to all other varieties (facial, axillary, etc.).
Process Overview
The core stages in processing a drug test result in a laboratory consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary handling of a sample into a laboratory’s framework. This involves verifying that the sample was sealed and dispatched correctly, allocating a random LAN (Laboratory Accessioning Number), and carrying out any extra data input not covered by an electronic chain of custody system.
Screening provides an initial assessment for illicit drugs. Although Screening offers a cost-effective means to eliminate drug use across numerous samples, a positive screening must be verified to hold up in court. Samples that are presumptively positive during Screening do necessitate a follow-up confirmation.
Should a sample appear presumptively positive in the Screening phase, additional hair is extracted from the original sample and readied for Extraction. In this phase, drugs are extracted from hair at a significantly lower concentration than alternative methods (e.g., urine or oral fluid), highlighting why hair drug screening is the most challenging method to execute.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed as necessary before confirmation. The entire laboratory process, from Accessioning to Confirmation, is overseen under the guidelines of the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.
