In West Sierra, California, Accredited Drug Testing provides comprehensive hair follicle drug testing. If you're seeking a hair drug or alcohol evaluation, we specialize in hair testing with centers available in all cities across the nation to administer these tests. A hair test requires 1.5 to 2 inches of hair, which can be sourced from your head or body, for drugs, alcohol/ETG, or other tailored testing.
Recently, hair follicle drug tests are increasingly favored for drug testing. Various employers, courts, and substance abuse experts demand hair tests over traditional urine tests. Employers enforcing zero-tolerance policies, judicial systems, and probation clients find these tests beneficial due to their extended drug detection period, up to 90 days, and collection in supervised settings. Despite this, for drug detection within recent 5 days, urine tests remain the reliable option.

Hair tests have become recognized as an effective method for detecting substance use. Hair captures a comprehensive history of alcohol and drug usage by embedding indicators within the strands as they grow. When taken near the scalp, hair can offer approximately a three-month detection period for substances. The collection process is straightforward, somewhat resistant to tampering, and easy to transport.
A 1.5-inch segment consisting of roughly 200 hair strands (similar in diameter to a #2 pencil) near the scalp provides about 100mg, which is the optimal amount for testing. For EtG, additional tests, or analyses beyond 10 panels, a 150mg specimen is advised. We suggest weighing the sample on a jeweler's scale. If scalp hair is inaccessible, a comparable quantity of body hair is an alternative. When mentioning head hair, it specifically means scalp hair. Body hair encompasses other types such as facial or axillary hair.
Process Overview
The process of analyzing a drug test consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into the lab’s system. This phase involves checking the integrity of the sealed and shipped sample, allocating a random LAN (Laboratory Accessioning Number), and completing any missing data entry not supplied by an electronic chain of custody system.
Screening acts as a preliminary examination for substances of abuse. Although screening is an economical way to dismiss drug presence in most samples, a positive finding must be verified to be valid in legal scenarios. Samples yielding presumptive positives during Screening require further verification.
In cases of a presumptive positive result in the Screening stage, additional hair is isolated from the initial sample and prepared for Extraction. During this stage, substances are extracted at much lower concentrations compared to other methods (e.g., urine or saliva), making hair drug testing a highly complex methodology.
Any positive screening results proceed to Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed prior to confirmation, as needed. The full laboratory workflow from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair protocols and compliance with ISO / IEC 17025 standards.
