Accredited Drug Testing offers extensive hair follicle substance assessment services in Howison, Mississippi. For hair or alcohol testing needs, we excel in hair analysis and maintain labs in all U.S. cities capable of hair sample testing. A minimum of 1.5 to 2 inches of hair is typically needed from the head or body. These tests detect drugs, alcohol/ETG, or can be tailored for specific substances.
In recent years, drug testing methodologies have progressively incorporated hair follicle analysis. Numerous employers, judicial systems, and substance specialists now prefer hair tests over traditional urine exams. Hair tests cater well to employers with strict drug policies, judicial clients, and probationers. Their main advantage is discerning substance use over 90 days, under watchful submission, rendering tampering near impossible. However, for detecting recent 5-day use, urine tests remain most precise.

Hair assessment is now recognized as an impactful method for uncovering drug and alcohol consumption. Hair offers an extended timeline of substance use by embedding biomarkers within the growing hair strands' fibers. When gathered close to the scalp, hair grants a detection window extending up to roughly three months for substances like alcohol and drugs. Hair collection is straightforward, quite resistant to tampering, and convenient to transport.
A sample measuring 1.5 inches comprising about 200 hair strands (around the thickness of a #2 pencil) nearest the scalp yields 100mg of hair, the recommended amount for both screening and verification. For EtG, additional tests, and those exceeding 10 panels, a specimen quantity of 150mg is advised. We propose using a jeweler’s scale for weighing the sample. If scalp hair is inaccessible, an equivalent volume of body hair can be obtained. When discussing head hair, we mean scalp hair specifically. Body hair encompasses all other types (like facial or underarm hair).
Process Overview
The four essential stages in the lab evaluation of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the first phase of processing a sample within a laboratory system. This phase involves ensuring the sample was sealed and dispatched correctly, allotting a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data input absent from an electronic chain of custody system.
Screening encompasses an initial speedy evaluation for illicit substances. Although Screening is an economical method to eliminate drug use in most samples, a positive outcome must be confirmed for court validity. Samples appearing presumptively positive during Screening necessitate a secondary confirmation.
For samples recorded as presumptively positive at the Screening stage, more hair is extracted from the initial sample to prepare for Extraction. In this phase, drugs are extracted from hair at a significantly lower concentration compare to other methods (such as urine or oral fluids), which is why hair drug screening is known to be the most challenging methodology to execute.
Verification of any positive screening result is performed via methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptively positive undergo washing prior to confirmation as needed. The entire lab procedure from Accessioning to Confirmation is overseen under the CAP (College of American Pathologists) Hair classification and the recognition of ISO / IEC 17025 standards.
