Accredited Drug Testing provides comprehensive hair follicle drug assessments in Portola Valley, California. Whether you require a hair drug or alcohol evaluation, we specialize in hair testing. We operate facilities across all U.S. cities that can conduct these tests. Generally, 1.5 to 2 inches of hair from the head or body is necessary. Hair tests can identify drugs, alcohol/ETG, or can be customized.
Recently, the popularity of hair follicle drug testing has grown considerably. Employers, courts, and substance abuse authorities increasingly prefer hair tests over traditional urine tests. Institutions with zero-tolerance policies, legal systems, and probationers favor hair tests for their extended drug detection period, generally up to 90 days. The test's observation process and complexity make it hard to manipulate, unlike urine tests, which are best for recent drug use within five days.

Using hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair offers a historical account of substance use by capturing biomarkers in the fibers of the growing hair shaft. Collected from near the scalp, hair can reveal up to a three-month detection timeline for substances. Collecting hair is straightforward, relatively tamper-resistant, and easy to transport.
A 1.5-inch section comprising roughly 200 hair strands (comparable to a standard #2 pencil) near the scalp yields 100mg, which is the preferred amount for initial and confirmatory testing. For EtG, additional tests, or for panels beyond 10, 150mg of the sample is suggested. It is advisable to use a jeweler's scale to measure the sample. In the absence of scalp hair, an equivalent quantity of body hair can be used. When mentioning head hair, it is specific to scalp hair. Body hair covers all other types (such as facial, axillary, etc.).
Process Overview
The four primary steps in laboratory processing of drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves incorporating a sample into a lab's workflow. This procedure verifies seal integrity and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any unprovided data entry from an electronic chain of custody.
Screening entails a preliminary, rapid assessment for drugs of abuse. While cost-effective for excluding drug use in most cases, a positive screen requires confirmation for legal admissibility. Samples with a presumptive positive screen necessitate further confirmation.
Should a sample test presumptively positive at the Screening phase, additional hair from the original sample is used for Extraction. In this phase, drugs are extracted from hair at a much lower concentration compared with other methods (e.g., urine or oral fluid), explaining why hair drug testing is the most challenging to conduct.
Positive screening confirmations are conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if needed. The comprehensive lab process, from Accessioning to Confirmation, is evaluated for both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
