Accredited Drug Testing offers comprehensive hair follicle drug examinations in Chula Vista, California. When in need of a hair-based drug or alcohol test, Accredited Drug Testing is the expert in this field, boasting testing facilities in every city across the nation, equipped to conduct hair tests. Typically, 1.5 to 2 inches of head or body hair is required. Hair analysis can detect drugs, alcohol/ETG, or provide tailored testing solutions.
In recent times, drug testing procedures increasingly incorporate the hair follicle method. Many employers, judicial systems, and substance abuse counselors prefer hair testing over the traditional urine test. Hair follicle tests are employed by businesses with strict no-drug policies, courts, and those on probation. Their main advantage is a longer detection window for drug usage—up to 90 days—collected in a supervised manner, making deception nearly impossible. Yet, for identifying drug use within the past five days, urine tests remain the precise option.

Hair testing is increasingly recognized as an effective method for detecting drug and alcohol consumption. Hair can archive a prolonged record of alcohol and drug usage by encasing biomarkers within the structure of the hair strand as it grows. When hair samples are collected near the scalp, they can offer up to a three-month detection timeframe for alcohol and other drugs. Hair collection is straightforward, challenging to tamper with, and easily transportable.
A hair sample of 1.5 inches, consisting of about 200 strands (comparable to the diameter of a #2 pencil) located nearest the scalp, provides around 100mg, which is the optimal amount for screening and confirmation. For EtG testing, additional tests, and those exceeding 10 panels, 150mg of hair is suggested. We advise measuring the sample with a jeweler’s scale. If scalp hair cannot be collected, an equivalent quantity of body hair is acceptable. References to head hair specifically pertain to scalp hair only, whereas body hair includes all other types (such as facial or axillary hair).
Process Overview
The four key stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial integration of a sample into a lab's system, which involves ensuring the sample was properly sealed and shipped, assigning it a random Laboratory Accessioning Number (LAN), and completing any necessary data entry not covered by an electronic chain of custody.
Screening acts as a preliminary evaluation for drugs of abuse. Although Screening is a cost-efficient approach to exclude drug usage in most samples, any positive results require confirmation to be legally admissible. Samples with presumptive positive results in Screening require further confirmation.
If the Screening phase yields a presumptive positive, additional hair is extracted from the original sample to prepare for Extraction. In this phase, drugs are extracted from hair at concentrations significantly lower than those found in other testing methods (e.g., urine or oral fluid), which contributes to the complexity of hair drug screening.
Confirmation of any positive results from Screening is conducted utilizing GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing as necessary before confirmation. The entire laboratory processing sequence, from Accessioning to Confirmation, is scrutinized under both CAP (College of American Pathologists) Hair specifications and ISO / IEC 17025 accreditation standards.
