Accredited Drug Testing offers comprehensive hair follicle drug testing in Weaverville, California. If you're in need of a hair drug or alcohol test, our expertise lies in hair analysis, with facilities across all cities nationwide capable of conducting such tests. Generally, 1.5 to 2 inches of hair from the head or body is required. These tests can detect drugs, alcohol/ETG, or be tailored for specific hair testing purposes.
Lately, drug testing methods have increasingly incorporated hair follicle drug tests. Many workplaces, judicial systems, and Substance Abuse experts now opt for hair tests over conventional urine analyses. Hair follicle tests are popular among employers enforcing strict anti-drug policies, courts, and probation officers. The key advantage of hair drug tests is their extended detection capability, often reaching up to 90 days, with collection under supervised conditions, and they are challenging to manipulate. Nevertheless, urine tests remain the preferred method for detecting recent drug use within 5 days.

Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. Hair retains a comprehensive record of substance use by embedding biomarkers within the shaft of the growing hair. When samples are collected near the scalp, they can offer approximately a 3-month detection window for substances like alcohol and other drugs. Hair sampling is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch segment consisting of roughly 200 hair strands (comparable to the diameter of a #2 pencil) nearest to the scalp yields 100mg, which is the ideal amount for screening and confirmation purposes. For EtG, additional substances, and/or tests exceeding 10 panels, 150mg of the specimen is advisable. Utilizing a jeweler’s scale for weighing the specimen is recommended. In the absence of scalp hair, an equivalent amount of body hair can be used. When discussing head hair, it refers exclusively to scalp hair. Conversely, body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial integration into a laboratory’s system. This process entails verifying the correct sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not supplied by an electronic chain of custody system.
Screening consists of an initial rapid assessment for drugs of abuse. Although Screening is a cost-efficient strategy to exclude drug usage for most samples, a positive screen necessitates confirmation for legal admissibility. Samples yielding a presumptive positive result in Screening must undergo further confirmation.
In scenarios where the Screening stage suggests a positive result, an additional portion of hair from the initial specimen is utilized for Extraction. During Extraction, drugs are removed from the hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug testing the most challenging method to execute.
Confirmation for any positive screen results is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Necessary washing of all presumptive positive samples is done before confirmation. The complete laboratory process, from Accessioning to Confirmation, is reviewed under the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
