Accredited Drug Testing provides comprehensive hair follicle drug assessments in Napa, California. For those requiring meticulous hair drug or alcohol screening, Accredited Drug Testing excels in hair analysis with numerous testing centers across cities Nationwide capable of conducting such tests. Typically, 1.5 to 2 inches of hair from the scalp or body are sufficient for most evaluations. Hair samples undergo examination for drugs, alcohol/ETG, or other tailored testing solutions.
In recent years, drug testing methods have increasingly incorporated hair follicle analysis. Both employers, judicial systems, and Substance Abuse experts are now favoring hair drug evaluations over traditional urine assessments. Hair follicle tests are deployed by employers with strict no-drug policies, judicial authorities, as well as probation officers. The main advantage lies in its extended detection time for drug usage, often up to 90 days, collected under supervision and virtually immune to deception. Yet, for detecting drug use within the last five days, urine testing remains the most precise method.

Hair testing is perceived as an effective means for detecting drug and alcohol consumption. Hair strands, through their fibers, capture biomarkers as they grow, offering a prolonged record of alcohol and drug use. Hair collected near the scalp can reveal drug and alcohol use within roughly a 3-month period. Collecting hair is straightforward, somewhat tamper-resistant, and uncomplicated to mail.
A sample measuring 1.5 inches, containing approximately 200 hair strands (equivalent to the girth of a #2 pencil) near the scalp provides 100mg of hair, which is the optimal amount for analysis and confirmation tests. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg specimen is advised. It's suggested to measure the sample using a jeweler’s scale. Should scalp hair not be available, an equivalent volume of body hair can be sampled. Head hair specifically refers to scalp hair. Body hair includes all other hair types, such as facial and axillary hair.
Process Overview
The administration of a drug test result in the laboratory consists of four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is entered into a lab's system. It involves verifying the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and filling in any missing data not captured by a digital chain of custody system.
Screening is the first assessment for substances of abuse. Though Screening is an economical method for ruling out drug use in most cases, a positive result must be validated for legal acceptance. Samples with a presumptive positive in Screening require further confirmation.
When a sample is presumptively positive at the Screening phase, additional hair is extracted from the original sample and set for Extraction. In this phase, substances are drawn from hair at a lower concentration compared to other methods such as urine or saliva, making hair drug tests the most complex to conduct.
Confirmation of any presumptive positive requires GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The whole lab process from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed as "hair follicle tests", the procedure actually examines the hair strand rather than the follicle under the scalp.
In Napa, hair follicle testing significantly outperforms traditional urine testing. Benefits of hair testing: A primary advantage is superior detection accuracy that urine tests simply can't match. With a longer detection window and greater reliability, hair testing provides a clearer picture of an individual's substance use history.
Urine tests can often miss substances used a few days prior. In contrast, hair tests cover up to a 90-day period, offering a more comprehensive assessment. This broader scope aids employers in maintaining a drug-free workplace more effectively than with traditional methods alone.
In Napa, the strength of hair follicle testing lies in its expansive detection window, capturing drug use over the last 90 days. Extended Detection Window: Such a comprehensive view is invaluable, providing employers with a detailed understanding of an individual's past substance use, contributing to more informed decision-making.
While other tests may only reflect recent usage, hair analyses offer insights into longer-term patterns. This advantage aids employers in making informed hiring choices and ensuring ongoing workplace safety, presenting a full spectrum of substance use behavior.
Hair follicle testing in Napa effectively minimizes the risk of sample tampering, delivering results that are both reliable and indisputable.
