In Riverside, Washington, Accredited Drug Testing offers comprehensive hair follicle drug testing services. If you're seeking a drug or alcohol hair test, our expertise lies in hair testing, with conveniently located centers nationwide capable of administering these tests. Typically, having 1.5 to 2 inches of hair available on the scalp or body suffices for testing. Our hair analyses can detect drugs, alcohol/ETG, and other custom options.
Over the last few years, hair follicle drug testing has increasingly become a favored technique for drug detection. Employers, the judicial system, and Substance Abuse experts more than ever prefer hair drug testing over traditional urine tests. Hair tests are popular with employers enforcing strict drug-free policies, courts, and individuals on probation. Its main advantage: a broader detection window—up to 90 days—collected through observable means, rendering cheating nearly impossible. Yet, for recent drug use (within five days), urine testing remains superior.

Hair analysis is increasingly recognized as a significant method for detecting the consumption of drugs and alcohol. By capturing biomarkers in the fibers of the hair as it grows, hair offers an extended historical record of substance use. When collected near the scalp, hair can reveal drug and alcohol use for up to about three months. The collection process for hair is straightforward, difficult to tamper with, and convenient to transport.
Collecting a 1.5-inch sample, around 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp, will yield 100mg of hair, the optimal amount for both screening and confirmation. For tests involving EtG, additional factors, or those exceeding 10 panels, a total of 150mg of hair is advised. It's suggested to weigh the hair on a jeweler's scale. In the absence of scalp hair, a comparable amount of body hair is suitable. References to head hair exclusively mean scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory handling of a drug test sample follows four essential phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of a sample into the lab's framework, ensuring the sample's seal and shipping are intact, assigning a random Laboratory Accessioning Number (LAN), and completing any leftover data entry missing from an electronic chain of custody system.
Screening includes a preliminary assessment for drugs of abuse. While Screening is economical for identifying drug use in the majority of samples, confirmations are necessary for any positive screens to be legally viable. Any samples that yield presumptive positive results during Screening require a subsequent confirmation.
Should a sample indicate a presumptive positive during Screening, additional hair is retrieved from the initial collection and readied for Extraction. In this phase, drugs are harvested from the hair in significantly lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screenings.
Confirmation of any positive screen is performed using methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing before confirmation if necessary. The full lab process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair criteria and the standards outlined in ISO/IEC 17025.
