Accredited Drug Testing provides comprehensive hair follicle drug testing services in Fremont, California. If you require a hair or alcohol test, Accredited Drug Testing excels in this area, and we have numerous testing facilities across the United States capable of conducting a hair test. Typically, 1.5 to 2 inches of hair from the head or body is necessary. Hair testing can be utilized for detecting drugs, alcohol/ETG, or other personalized testing options.
Recently, the use of hair follicle drug tests has become more prevalent in the field of drug testing. Employers, judicial systems, and substance abuse professionals often opt for hair testing over urine testing. Hair follicle drug tests are indispensable for employers enforcing zero-tolerance drug use regulations, for court cases, and for those on probation. The major advantage of hair tests is their extended detection period for drug use, typically up to 90 days, coupled with the observed collection method, making them nearly foolproof. Still, if testing for substance use within the last 5 days is required, urine tests prove most effective.

Hair analysis is increasingly recognized as an effective means for detecting substance usage. Hair captures a prolonged history of alcohol and drug consumption by embedding biomarkers within the strands as they grow. When taken from near the scalp, hair offers a detection window that lasts up to approximately three months for alcohol and drugs. The collection of hair is straightforward, relatively resistant to tampering, and easy to transport.
A sample of 1.5 inches, consisting of roughly 200 hair strands (about the width of a #2 pencil) nearest to the scalp, yields 100mg of hair, which is the preferred sample size for screening and verification. For EtG, additional tests, or tests exceeding 10 panels, 150mg of the sample is advised. Utilizing a jeweler’s scale for weighing the sample is suggested. If scalp hair is not accessible, a comparable amount of body hair can be used. When head hair is referenced, it specifically means scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result typically involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first phase, where a sample is introduced into a laboratory's system. This step includes verifying proper sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data not provided by an electronic chain of custody system.
Screening consists of an initial fast check for substance abuse. Although Screening is an economical method to rule out substance use for most samples, a positive result requires confirmation to be legally acceptable. Any samples that test presumptively positive in Screening necessitate additional confirmation.
If a sample yields a presumptively positive result during the Screening phase, more hair is extracted from the initial specimen for the Extraction process. Here, drugs are separated from hair at significantly lesser concentrations compared to other techniques (e.g., urine or oral fluid), making hair drug screening the most complex methodology to conduct.
Verification of any positive screening outcome is undertaken using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are washed prior to confirmation if required. The whole laboratory procedure from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.
