Accredited Drug Testing provides comprehensive hair follicle drug assessments in Herndon, Virginia. If a hair drug or alcohol test is essential, we excel in hair analysis, with facilities in every city nationally equipped to conduct a hair examination. Typically, 1.5 to 2 inches of scalp or body hair is required. Hair assessments can identify drugs, alcohol/ETG, or other tailored testing solutions.
Recently, the trend towards hair follicle drug testing has increased. More employers, legal systems, and substance experts now prefer a hair test over traditional urine analysis. This method is favored by zero-tolerance workplaces, courts, and probation-related cases. Key advantages include a comprehensive 90-day detection window, an observable sample collection, and enhanced security against tampering. Nonetheless, urine tests remain more precise for detecting recent drug use within the past five days.

Hair analysis is increasingly regarded as an effective method for identifying drug and alcohol consumption. Hair can archive a lengthy overview of alcohol and drug intake by securing biomarkers within the fibers of the hair as it grows. When taken from near the scalp, hair can indicate alcohol and drug usage for up to three months. Collecting hair is straightforward, challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (similar in diameter to a #2 pencil) nearest to the scalp produces 100mg of hair, which is the optimal amount for both screening and confirmation tests. For EtG, additional tests, or those exceeding 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is not available, an equivalent volume of body hair can be collected. "Head hair" pertains solely to scalp hair, while "body hair" covers all other hair types (such as facial and axillary).
Process Overview
The primary phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary treatment of a sample into a lab’s framework. This step ensures that the sample was sealed and dispatched correctly, allocates a random LAN (Laboratory Accessioning Number), and finalizes any remaining data entry not managed by an electronic chain of custody process.
Screening is an initial rapid assessment for drug abuse. While Screening is an economical method to exclude drug usage in most samples, a positive result necessitates confirmation to be valid in court. Any samples with a preliminary positive result in Screening require further confirmation.
If Screening yields a presumptive positive result, extra hair is extracted from the original sample and prepped for Extraction. During this phase, drugs are isolated from hair at notably diminished concentrations than in other methods (such as urine or oral fluid), making hair drug analysis especially challenging to execute.
Any positive screening outcomes undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before Confirmation as necessary. The entire lab process from Accessioning through Confirmation is reviewed under both the CAP (College of American Pathologists) Hair specification and the accreditation to ISO / IEC 17025 regulations.
