Accredited Drug Testing offers comprehensive hair follicle drug testing in Kentfield, California. If you're in need of a hair drug or alcohol test, Accredited Drug Testing specializes in such tests, with facilities available nationwide to conduct a hair test. Generally, 1.5 to 2 inches of hair from the crown or body is required. Hair testing can screen for drugs, alcohol/ETG, or other customized options.
Recently, hair follicle drug tests have become a more common method for drug testing. Many employers, courts, and substance abuse experts prefer hair drug tests over standard urine tests. Employers with zero-tolerance drug policies, courts, and probationary individuals utilize these tests for their longer detection period, up to 90 days, and because they are difficult to tamper with. For recent drug use within 5 days, urine tests remain more accurate.

Hair analysis has emerged as an effective means for detecting substance and alcohol consumption. Hair offers an extended timeline of alcohol and drug use by capturing biomarkers within the fibers of the growing strand. When taken near the scalp, hair can present approximately a three-month period of detection for both alcohol and drugs. Hair is straightforward to collect, moderately challenging to tamper with, and convenient to transport.
A 1.5-inch portion comprising around 200 strands (comparable to a #2 pencil width) adjacent to the scalp yields 100mg, which is the optimal size for both screening and confirmation tests. For EtG, additional assays, and/or tests exceeding 10 panels, a 150mg sample is advisable. It's recommended to ascertain the sample's weight using a jeweler’s scale. In absence of scalp hair, an equivalent quantity of body hair can be sourced. The term head hair pertains solely to scalp hair, whereas body hair includes other types such as facial and axillary hair.
Process Overview
The laboratory processing of a drug test result encompasses four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial appointment of a sample into a lab’s system. This involves confirming the sample’s sealing and shipment, allotting a unique LAN (Laboratory Accessioning Number), and performing any supplementary data entry absent from an electronic chain of custody.
Screening consists of an initial rapid appraisal for drugs of abuse. A Screening test is a cost-effective approach to dismiss drug use in most samples, though a positive screen mandates confirmation for legal admissibility. Samples that show a presumptive positive in Screening necessitate a further confirmatory test.
In cases where a sample tests presumptively positive during Screening, additional hair is extracted from the original batch and readied for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations than alternative methods (e.g., urine or oral fluid), making hair drug analysis a highly challenging procedure.
Confirmation of any positive Screening outcome is performed with GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples testing presumptive positive are pre-washed before confirmation as required. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Note: Despite being commonly termed as "hair follicle tests", the analysis targets the hair strand rather than the follicle itself beneath the scalp

The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation.
