Accredited Drug Testing provides comprehensive hair follicle evaluations in Nicasio, California. If a test for drugs or alcohol via hair is necessary, Accredited Drug Testing excels in this field, with testing centers across the nation including Nicasio. Hair strands must generally be 1.5 to 2 inches long for testing from the head or body, enabling analysis for substances like drugs, ETG, or through specialized tests.
Hair follicle drug testing has increasingly become a method of choice recently. Employers, legal authorities, and addiction specialists often opt for hair tests over urine tests. Their advantages include a lengthy detection period, reaching up to 90 days, which is hard to falsify. Still, for identifying recent drug use within five days, urine tests hold their accuracy advantage.

Hair testing has emerged as a robust method for detecting drug and alcohol usage. Hair retains a historical record of alcohol and drug use by embedding biomarkers within the strands as they grow. When obtained near the scalp, hair can offer a detection window of up to roughly three months for alcohol and drugs. Collecting hair is straightforward, relatively challenging to tamper with, and simple to transport.
A sample length of 1.5 inches, which consists of about 200 hair strands (comparable to a #2 pencil), collected nearest to the scalp, yields 100mg of hair, which is the preferred sample size for screening and confirming. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is advised. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair cannot be collected, an equivalent amount of body hair is acceptable. References to head hair are specifically about scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of processing a sample within a laboratory system. It includes confirming the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and inputting any additional data not available through an electronic chain of custody system.
Screening serves as an initial rapid evaluation for drugs of abuse. Although Screening is a cost-efficient method to exclude drug use in most samples, a positive result must be validated to be legally acceptable. Any samples with a presumptive positive result in Screening require further confirmation.
Should a sample yield a presumptive positive result during Screening, additional hair is taken from the sample and prepared for Extraction. Drugs are removed from the hair in this stage at much lower concentrations compared to other methodologies (e.g., urine or oral fluid), making hair drug screening a challenging process to execute.
Confirmation for any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a washing process before confirmation when necessary. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
