Accredited Drug Testing provides comprehensive hair follicle testing services in La Crescenta, California. If you require a test for drugs or alcohol through hair analysis, Accredited Drug Testing is equipped for such testing, with centers across the nation. For accurate results, approximately 1.5 to 2 inches of hair from the head or body is needed. Tests can detect drugs, alcohol/ETG, or other tailored options.
The trend towards utilizing hair follicle tests for drug detection has grown, replacing traditional urine tests. Employers, judicial systems, and substance professionals now favor hair drug tests. These tests are invaluable for zero-tolerance environments, legal scenarios, and probation settings, offering up to 90 days detection. Despite this, urine tests remain more precise for recent use detection, up to 5 days.

Hair analysis has gained recognition as an effective method for detecting substance and alcohol use. Hair retains a long-term record of alcohol and various drugs by capturing biomarkers in the strands of growing hair. Collected near the scalp, hair can reveal up to approximately a 3-month timeframe for alcohol and other drugs. Hair is straightforward to collect, somewhat challenging to tamper with, and simple to ship.
A 1.5-inch piece of about 200 hair strands (around the width of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample for checking and verifying. For EtG, add-ons, and/or assessments exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the sample on a jeweler’s scale. If scalp hair is not present, a similar quantity of body hair can be obtained. When mentioning head hair, we are talking about scalp hair only. Body hair includes all other types of hair (facial, axillary, etc.).
Process Overview
The four principal steps in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial handling of a sample into a laboratory’s system. This step verifies the sample was sealed and sent correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any further data entry absent from an electronic chain of custody system.
Screening includes an initial rapid assessment for substances of abuse. Screening is a cost-efficient method to exclude drug use in most samples; however, a confirmed screen is essential for court admissibility. Any samples that appear positive in Screening require further confirmation.
If a sample suggests a positive result in the Screening phase, more hair is drawn from the original sample and prepared for Extraction. During this phase, drugs are extracted from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), thus making hair drug screening the most challenging methodology to conduct.
Confirmation of any positive screening result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed prior to confirmation as needed. The entire lab process from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
