Accredited Drug Testing offers comprehensive hair follicle drug assessments in Stanford, California. If a hair drug or alcohol test is required, our company specializes in hair evaluations and provides service in cities nationwide. Most commonly, you need 1.5 to 2 inches of head or body hair to be tested. Hair assessments are capable of detecting drugs, alcohol/ETG, or other tailored testing types.
Recently, drug testing methods have increasingly adopted the hair follicle approach. Employers, courts, and substance misuse experts often prefer hair drug tests over traditional urine examinations. Hair follicle assessments are favored by companies, legal systems, and probation officers due to their zero-tolerance policy compliance. They are beneficial as they offer a longer drug detection timeline, generally up to 90 days, are collected under observation, and are nearly impossible to manipulate. For short-term use detection within five days, urine tests remain most effective.

Hair testing is regarded as an effective method for identifying drug and alcohol consumption. Hair captures a detailed timeline of substance use by embedding biomarkers within the expanding hair strand's fibers. A strand of hair, cut near the scalp, offers an alcohol and drug detection window of up to roughly three months. Hair is easy to collect, less likely to be tampered with, and convenient to transport.
A 1.5-inch hair sample, consisting of roughly 200 strands (around the diameter of a #2 pencil) closest to the scalp, yields 100mg—the optimal amount for both screening and confirmation. For EtG, additional tests, and analyses exceeding 10 panels, a 150mg collection is advised. We suggest using a jeweler's scale for precise measurement. Should scalp hair be unobtainable, an equivalent quantity of body hair is acceptable. When specifying head hair, we specifically mean scalp hair, while body hair encompasses all other varieties such as facial or axillary hair.
Process Overview
The key stages in the laboratory evaluation of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially entered into a laboratory's system. This phase includes confirming the sample's proper sealing and shipping, providing a unique LAN (Laboratory Accessioning Number), and completing any further data entry absent from an electronic custody chain system.
Screening involves a preliminary swift evaluation for signs of drug abuse. Although Screening is an economical method to exclude drug use in most samples, a positive screening necessitates confirmation for court admissibility. Samples yielding presumptive positives in Screening must undergo a secondary validation.
Should a sample exhibit a presumptive positive at the Screening stage, additional hair is extracted from the primary sample and prepared for Extraction. At this juncture, drugs are retrieved from hair at notably lower concentrations compared to other methods (e.g., urine or oral fluid), attesting to hair drug screening's complex nature.
Any confirmed positive screening outcomes are validated using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing where essential before confirmation. The complete laboratory process, from Accessioning to Confirmation, falls under scrutiny based on both the CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 standard accreditation.
