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.
Hair testing has emerged as a strong method for detecting drug and alcohol consumption. Hair serves as a record of alcohol and drugs over time by encasing biomarkers in the fibers of the developing hair strand. When taken near the scalp, hair can provide an approximate detection period of 3 months for alcohol and other substances. Hair is easy to gather, relatively challenging to tamper with, and simple to transport.
A segment of 1.5 inches consisting of around 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal sample for both screening and validation. For EtG, additional tests, or those exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale for weighing the sample. If scalp hair is not accessible, a comparable quantity of body hair may be utilized. When discussing head hair, it specifically pertains to scalp hair. Body hair includes all other hair varieties (beard, armpit, etc.).
Process Overview
The four primary stages in lab processing of drug test results are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially integrated into the lab's system. This step involves ensuring the sample's seal and shipment are intact, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic custody chain.
Screening offers a preliminary swift analysis for drugs of abuse. Although Screening is a cost-efficient approach to discount drug usage in most samples, a positive result needs confirmation for legal admissibility. Samples that test presumptively positive in Screening require a follow-up verification.
If a sample is tentatively positive during the Screening phase, further hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are isolated from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most complex method to execute.
Verification of any positive screening outcome is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleansed prior to confirmation if needed. The complete lab procedure from Accessioning to Confirmation undergoes scrutiny under both CAP (College of American Pathologists) Hair criteria and the ISO/IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Though commonly referenced as "hair follicle tests", the analysis is conducted on the hair strand rather than the follicle beneath the scalp.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation.
