Accredited Drug Testing offers comprehensive hair follicle drug testing services in San Lorenzo, California. Whether you're in need of a hair drug or alcohol test, we specialize in hair-based testing and boast centers in cities across the nation capable of this service. Generally, 1.5 to 2 inches of hair are needed from the crown of the head or body. Hair tests can check for drugs, alcohol/ETG, or other tailored testing solutions.
In recent times, hair follicle drug tests have increasingly been adopted as a means of drug testing. Employers, courts, and substance abuse specialists are opting for hair over traditional urine tests. Hair drug tests are favored by organizations with zero-tolerance policies against drug use, courts, and probation officers. The main advantage of hair drug tests is their extended detection period, typically up to 90 days, collected under supervised conditions, and are hard to tamper with. However, for identifying drug use within the last five days, urine tests remain the most precise.

Hair analysis is increasingly viewed as an effective means for identifying drug and alcohol consumption. The fibers of actively growing hair capture biomarkers, creating a long-term record of substance use. When taken near the scalp, hair offers an approximately 3-month detection timeframe for both alcohol and drugs. Collection is straightforward, relatively tamper-resistant, and easily shippable.
A segment of hair 1.5 inches in length and around 200 strands (comparable to the thickness of a #2 pencil) nearest to the scalp typically yields 100mg, which is optimal for evaluation and verification. For tests involving EtG, additional panels, beyond 10, require 150mg. We advise using a jeweler’s scale for precise measurement. If scalp hair is inadequate, an equivalent measure of body hair may suffice. Specific reference to head hair pertains exclusively to scalp hair, whereas body hair encompasses all other varieties (such as facial or axillary hair).
Process Overview
The laboratory processing of a drug test comprises four crucial steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially entered into a lab's system. This step certifies the sample's proper sealing and shipping, assigns an arbitrary LAN (Laboratory Accessioning Number), and finalizes any missing details that an electronic custody protocol might omit.
Screening is a preliminary and efficient assessment for substance abuse. Although cost-effective at excluding drug use for most samples, a positive result must be verified for legal acceptability. Samples presumed positive from Screening must undergo further validation.
If Screening indicates a presumptive positive, excess hair from the original sample is extracted for further Examination. This phase extracts drugs at significantly reduced levels compared to other methods (such as urine or oral fluids), highlighting the complexity of hair drug testing.
Positive screenings necessitate Confirmation through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Pre-confirmation, all samples suspected positive are thoroughly cleansed as required. The comprehensive lab process, from Accessioning through Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although termed "hair follicle tests", the examination targets the hair strand itself, not the follicle from beneath the scalp.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. 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.
