In Corte Madera, California, Accredited Drug Testing offers comprehensive hair follicle drug testing. If your need calls for a hair drug or alcohol evaluation, our expertise lies in hair testing with centers in cities across the Nation, capable of performing these assessments. Generally, a person needs to have between 1.5 to 2 inches of hair on the crown or body for testing. Hair testing is efficient for drugs, alcohol/ETG, or other tailored hair analyses.
Recently, the trend in drug testing leans toward utilizing a hair follicle drug test more than ever. This shift is noticed among employers, courts, and Substance Abuse specialists opting for hair tests over the usual urine tests. Hair follicle tests are crucial for zero-tolerance employers, judicial systems, and those on probation. Their main advantage lies in an extended detection duration for drug consumption, typically up to 90 days, collected under observation and hard to falsify. However, for detecting drug use within five days, urine tests remain the most reliable.

Hair testing is recognized as a robust method for detecting drug and alcohol consumption. Hair offers an extended chronology of substance use by embedding biomarkers within the hair strand's fibers as it grows. When hair is collected near the scalp, it can provide up to a three-month detection period for alcohol and drugs. The collection of hair is straightforward, altering its integrity is challenging, and it is easily shippable.
Gathering a 1.5-inch sample, approximately 200 strands or akin to a #2 pencil's size, from the scalp results in 100mg of hair, which is optimal for both screening and confirmation. For testing such as EtG or panels exceeding 10, 150mg of the sample is advised. It's suggested to weigh the sample with a jeweler’s scale. If scalp hair isn't accessible, a similar quantity of body hair can be used. Mentioning head hair pertains exclusively to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
There are four primary steps in processing a drug test outcome in the laboratory: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step where a sample is incorporated into the lab’s system. This step includes checking that the sample is appropriately sealed and dispatched, assigning it a unique LAN (Laboratory Accessioning Number), and completing any data input absent from an electronic chain of custody system.
Screening involves a swift preliminary examination for substance abuse. Screening is a cost-effective method to eliminate drug use in the majority of samples; however, a positive screen requires confirmation to be valid in legal contexts. Samples that test presumptively positive during Screening need subsequent confirmation.
For samples that indicate positivity in Screening, additional hair is retrieved from the original sample and readied for Extraction. During this phase, drugs are drawn from hair at substantially lower concentrations than in other methods (e.g., urine or oral fluid), which underscores the complexity of performing hair drug screening.
Confirmation of any positive screens is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation as warranted. The entire lab process from Accessioning to Confirmation undergoes review according to both the CAP (College of American Pathologists) Hair certification and accreditation aligned with ISO / IEC 17025 standards.
