Situated in Halifax, Virginia, Accredited Drug Testing offers comprehensive hair follicle drug testing. If you require a drug or alcohol hair test, we at Accredited Drug Testing focus on this area, offering testing facilities nationwide capable of performing thorough tests. Generally, 1.5 to 2 inches of hair from the head or body is required. Hair assessments can be conducted for drugs, alcohol/ETG, or personalized testing options.
Recently, hair follicle drug testing has become more commonplace compared to the traditional methods. Many employers, judicial systems, and Substance Abuse experts are turning to hair tests over conventional urine exams. Hair tests are preferred by organizations with strict drug policies, the court system, and those on probation. Notably, hair tests can detect drug use over a lengthy period—up to 90 days—which provides a reliable and tamper-proof alternative. However, urine tests are still more accurate for recent use within the last 5 days.

Hair testing is widely recognized as an effective method for identifying drug and alcohol consumption. Providing an extensive historical record, hair captures biomarkers within the fibers of the growing strand. Collecting samples near the scalp allows for a detection period of approximately three months for alcohol and drugs. The process of collecting hair is straightforward, challenging to tamper with, and convenient to transport.
Gathering a 1.5-inch sample comprising around 200 strands (approximately the thickness of a standard #2 pencil) closest to the scalp results in 100mg of hair, which is the preferred sample for analysis and confirmation. For EtG, additional tests, or panels exceeding 10, 150mg of the sample is advisable. Utilizing a jeweler’s scale is recommended for weighing the specimen. In the absence of scalp hair, a similar quantity of body hair is acceptable. When discussing head hair, we solely refer to scalp hair, while body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the lab’s system. This stage includes verifying the proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody system.
Screening involves a preliminary rapid test for substances of abuse. While Screening is a cost-efficient strategy to negate drug use in most samples, a positive result necessitates confirmation for legal proceedings. Any samples presumptively positive in Screening require a follow-up confirmation.
Should a sample test positive during the Screening phase, additional hair is taken from the original specimen and prepared for Extraction. Here, drugs are extracted from hair at considerably lower concentrations than in alternate methodologies (e.g., urine or oral fluid), contributing to the complexity of hair drug testing.
Confirmation of any positive Screening results is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing before confirmation as required. Throughout the laboratory procedure from Accessioning to Confirmation, all processes are evaluated under the CAP (College of American Pathologists) Hair standard and the ISO / IEC 17025 accreditation.
