In Grundy, Virginia, Accredited Drug Testing offers comprehensive hair follicle drug tests. Whether it's a test for drugs or alcohol, our network of testing sites across the nation provides specialized hair testing services. Typically, 1.5 to 2 inches of head or body hair is necessary for testing. We provide analyses for drugs, alcohol/ETG, and other customized assessments.
Hair follicle drug testing has become increasingly common in recent times. Employers, judicial systems, and addiction specialists often opt for hair tests over traditional urine analysis. These tests are favored by entities with zero-tolerance policies, legal requirements, and probationary monitoring. The main advantage is their extended detection window, up to 90 days, along with secure collection methods, which make tampering nearly impossible. However, urine tests are still best for detecting recent drug use within the past 5 days.

Hair testing is recognized as an effective method for identifying drug and alcohol usage. Hair captures a long-term record of drugs and alcohol by securing biomarkers within its developing fibers. Hair collected near the scalp may reveal a detection timeline for alcohol and drugs extending up to about three months. Collecting hair is straightforward, relatively tough to tamper with, and hassle-free to transport.
A sample measuring 1.5 inches and consisting of roughly 200 hair strands (comparable to a #2 pencil thickness) taken nearest the scalp provides 100mg of hair, which is the optimal amount for both screening and verification. For EtG, additional tests, and tests exceeding ten panels, it is advisable to provide 150mg of the specimen. It's suggested to measure the specimen's weight using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair is acceptable. References to head hair specifically mean scalp hair. Body hair encompasses all other types, such as facial and axillary hair.
Process Overview
The path of processing a drug test in the laboratory encompasses four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial sample processing step managed within a laboratory’s system. This stage checks that the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and fulfills additional data entry requirements not included in an electronic chain of custody system.
Screening offers a preliminary, swift assessment for substance abuse. While it is an economical method to exclude drug usage from most samples, positive results in Screening require confirmation for legal admissibility. Therefore, samples that test presumptively positive in Screening must undergo further verification.
Following a presumptive positive result in the Screening phase, extra hair from the original sample is extracted for the Extraction stage. During Extraction, drugs are derived from hair at concentrations significantly less than those used in other testing methods like urine or oral fluid, contributing to hair drug screening’s complexity as a testing methodology.
Confirmation of any positive screening outcomes is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before Confirmation if necessary. The entire process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and conformance with ISO / IEC 17025 standards.
