Accredited Drug Testing offers comprehensive drug screening through hair follicle analysis in Coulterville, California. Whether you require testing for drugs or alcohol, our centers are available in numerous cities across the nation. A minimum of 1.5 to 2 inches of hair is typically needed from the head or body. Hair tests can detect drugs, alcohol/ETG, or other specified substances.
Recently, hair follicle drug tests have become a more popular method of screening for drug use. Courts, employers, and Substance Abuse experts increasingly prefer this method over urine tests. Hair follicle tests are ideal for environments with zero-tolerance policies, providing a detection window of up to 90 days with an observed collection process, making them nearly uncheatable. However, for drug use within the past 5 days, urine tests remain the most accurate.

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, offering a long-term record of substance use. When taken near the scalp, it can reveal drug and alcohol use for up to three months. Collecting hair is straightforward, somewhat resistant to tampering, and simple to transport.
A 1.5-inch segment of about 200 hair strands (similar in size to a #2 pencil) closest to the scalp provides 100mg of hair, the perfect sample for screening and confirmation. For EtG, extra tests, and/or panels exceeding 10, a 150mg sample is advised. We suggest measuring the sample with a jeweler’s scale. If scalp hair isn’t available, collect an equivalent amount of body hair. Head hair applies only to scalp hair. Body hair covers all other types (facial, axillary, etc.).
Process Overview
The key steps in lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the first processing of a sample into a lab’s system. It verifies the sample’s sealed and correct shipping, assigns a random LAN (Laboratory Accessioning Number), and fills in any extra data entry not provided by an electronic chain of custody system.
Screening offers an initial quick check for substance abuse. While Screening is cost-effective for ruling out drug use in most samples, a positive screen must be confirmed for legal admissibility. Samples that test presumptively positive require a secondary confirmation.
If a sample shows presumptive positivity in the Screening stage, additional hair is taken from the initial sample and prepped for Extraction. This process pulls drugs from hair at much lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug testing the hardest to perform.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples are washed before confirmation if necessary. The entire lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
