In Hamlin, Texas, Accredited Drug Testing offers thorough hair follicle drug assessments. Whether it's for drug or alcohol testing, our centers across the nation, including all cities, are equipped to conduct hair testing. Typically, 1.5 to 2 inches of head or body hair is required. Hair tests can detect drugs, alcohol (ETG), or can be customized for other needs.
Hair follicle drug tests have recently gained popularity for drug testing. Employers, legal systems, and abuse specialists often prefer this over urine tests. Those with zero-tolerance policies, the judiciary, and individuals on probation rely on it. The main advantage is its long-term detection window of up to 90 days, with observed sample collection, making it difficult to falsify. However, when recent use within 5 days is a concern, the urine test remains highly accurate.

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of drug and alcohol use by integrating biomarkers within the fibers of the hair as it grows. When sourced near the scalp, hair can reveal alcohol and other drug usage for up to around three months. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch section of approximately 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp will produce 100mg of hair, which is optimal for both initial screening and further confirmation. For EtG, additional tests, and/or analyses exceeding 10 panels, a 150mg sample is advisable. We suggest using a jeweler’s scale to measure the sample weight. If scalp hair isn’t available, a comparable quantity of body hair may be gathered. When we mention head hair, we mean only scalp hair. Body hair encompasses any other types like facial or axillary hair.
Process Overview
The laboratory analysis of a drug test result comprises four major phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning represents the initial step of processing a sample into the lab's workflow. This step ensures the sample was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any additional information entry not handled by an electronic chain of custody system.
Screening serves as an initial assessment for the presence of drugs of abuse. Although Screening offers a budget-friendly means to exclude drug use in most samples, a positive result from Screening must be verified to be valid in legal situations. Any samples that test presumptively positive during Screening necessitate a subsequent confirmation.
Should a sample test positive during the Screening phase, additional hair is extracted from the original sample and then readied for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations compared to other techniques (e.g., urine or saliva), making hair drug testing one of the most challenging methodologies to perform.
Confirmation of any positive result from screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed as required before confirmation. The full laboratory workflow, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.
