Accredited Drug Testing provides comprehensive hair follicle drug testing in Petrolia, California. If a hair drug or alcohol test is required, Accredited Drug Testing excels in hair testing and operates testing centers in every city across the Nation that can conduct a hair test. Typically, 1.5 to 2 inches of hair from the crown of your head or body can be used. Hair tests can be assessed for drugs, alcohol/ETG, or other tailored hair testing needs.
In recent years, the inclusion of hair follicle drug tests in drug testing methods has become more prevalent. Many employers, courts, and Substance Abuse professionals now prefer a hair drug test over the conventional urine test. Hair follicle drug tests are employed by employers with strict drug use policies, courts, and individuals on probation. The main advantage of hair follicle drug testing is its extended detection period for drug use, generally up to 90 days, collected through an observed collection process, making it nearly impossible to tamper with. However, when testing for drug use within the last 5 days, the urine test remains the most precise method.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Seen as an effective means for identifying drug and alcohol consumption, hair testing is gaining recognition. Hair can reveal a prolonged history of substance use by capturing biomarkers within the fibers of the growing hair shaft. When collected near the scalp, this method can offer an approximate 3-month detection period for alcohol and drugs. Hair is easy to obtain, relatively tamper-proof, and convenient to transport.
An ideal sample is a 1.5-inch section of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp, yielding 100mg of hair for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is suggested. It is advised to weigh the sample using a jeweler’s scale. If scalp hair is unavailable, a similar amount of body hair can be used. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other types (like facial or axillary).
Process Overview
There are four primary steps in processing a drug test result through the laboratory: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of entering a sample into the lab's system. This process includes confirming the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and inputting any supplementary data not captured by an electronic chain of custody.
Screening involves a preliminary check for substances of abuse. While Screening is a budget-friendly method to rule out most drug use cases, a positive result mandates confirmation to be court-admissible. Samples indicating a presumptive positive in Screening require secondary verification.
Should a sample show presumptive positivity during Screening, additional hair is taken from the original sample for Extraction. In this phase, drugs are extracted from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening notably more challenging to perform.
Confirmation of any positive Screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to necessary confirmation. The complete laboratory procedure, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.
