In Mad River, CA, Accredited Drug Testing offers comprehensive hair follicle drug testing. If you're seeking a hair or alcohol test, our expertise in such assessments is unmatched, with centers spread across all cities nationwide. Typically, a minimum of 1.5 to 2 inches of hair from the crown or body is required for testing. These tests can detect drugs, alcohol/ETG, or custom substances.
Over recent years, hair follicle drug tests have gained prominence in drug testing procedures. Many professionals, such as employers, courts, and substance abuse experts, prefer them over standard urine tests. Organizations with zero-tolerance policies, court systems, and individuals on probation commonly use these tests due to their extended detection period of up to 90 days. They involve an observed collection process, minimizing cheating risks. Nonetheless, urine tests remain the best for recent drug use detection within five days.

Hair testing has emerged as a significant method for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and drug use by capturing biomarkers in the fibers of the hair strand as it grows. When harvested near the scalp, hair can offer up to a 3-month detection span for alcohol and various drugs. The collection process for hair is straightforward, relatively challenging to tamper with, and convenient to transport.
A sample size of 1.5 inches, consisting of roughly 200 hair strands (comparable to a #2 pencil's diameter), will provide 100mg of hair, which is ideal for screening and confirming. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the hair sample is advised. It is recommended to weigh the sample using a jeweler's scale. If scalp hair cannot be collected, an equal quantity of body hair may be used. When head hair is mentioned, it specifically means scalp hair. Body hair includes all other hair types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the primary step of entering a sample into a lab’s system. This step includes ensuring the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent from an electronic chain of custody system.
Screening encompasses an initial quick test for substances of abuse. Though Screening offers a cost-effective method to negate drug use in most samples, a court-admissible result requires confirmation of a positive screen. Samples showing presumptive positive results in Screening warrant additional confirmation.
If the Screening stage indicates a presumptive positive result, additional hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are extracted from the hair at a substantially lower concentration than in other methods (e.g., urine or oral fluid), which contributes to the complexity of hair drug screening.
Confirmation of a positive screen result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive findings undergo washing before confirmation as required. The complete lab procedure, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
