Accredited Drug Testing offers comprehensive hair follicle drug assessments in Homestead Valley, CA. If a hair drug or alcohol test is required, our specialty in hair testing is supported by nationwide centers ready to conduct these tests. Typically, hair length should be 1.5 to 2 inches from the crown or body. Tests can detect drugs, alcohol/ETG, and provide custom options.
Recently, hair follicle testing has become a preferred method for drug testing. Employers, courts, and substance abuse experts increasingly select hair drug tests over urine tests. These tests are ideal for employers with zero-tolerance policies, as well as for courts and those on probation. The main advantage is a broader detection window of up to 90 days, with an observed collection process, making cheating difficult. However, for recent drug use, under five days, a urine test remains most accurate.

Hair analysis has gained recognition as an effective method for detecting substance and alcohol use. Hair captures a long-term record of alcohol and other drugs by incorporating biomarkers within the growing hair strand's fibers. When gathered near the scalp, hair can offer up to roughly a 3-month detection timeframe for alcohol and other drugs. The collection of hair is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch segment comprising about 200 hair strands (around the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the perfect amount for screening and verification. For EtG, expanded panels, and/or screenings exceeding 10 panels, a 150mg sample is advisable. It is suggested to measure the sample using a jeweler’s scale. If scalp hair is unattainable, a comparable quantity of body hair can be used. When referencing head hair, we specifically mean scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The four key stages in the laboratory evaluation of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary processing of a sample into a lab’s system. This process ensures that the sample was properly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry not already provided by an electronic chain of custody system.
Screening involves a preliminary swift analysis for drugs of abuse. Although Screening is a cost-efficient strategy to exclude drug use in most samples, a positive screen must be confirmed to be admissible in legal settings. Any samples identified as possibly positive in Screening do require additional confirmation.
If a sample shows potential positivity in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are isolated from hair at much lower concentrations than in alternative methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.
Any positive screening outcome is verified via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with potential positivity are cleansed before confirmation if needed. The comprehensive laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 benchmarks.
