Organizations, legal entities, and addiction specialists are opting for this test over traditional urine tests. These tests cater to employers with strict no-drug policies, legal settings, and those on probation.

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 tests are now recognized as a formidable tool for detecting drugs and alcohol usage. Hair retains a timeline of alcohol and drug use by capturing biomarkers within the strands' fibers. When clipped near the scalp, hair offers a detection window for drugs and alcohol extending up to about 3 months. The collection process is straightforward, challenging to tamper with, and easy to transport.
Obtaining a 1.5-inch section of roughly 200 hair strands, similar in size to a #2 pencil, nearest the scalp will yield 100mg of hair, the optimal amount for both screening and confirmatory tests. For EtG, add-ons, or tests exceeding 10 panels, it's suggested to use 150mg of the sample. It's advisable to measure the sample on a jeweler's scale. Where scalp hair isn't available, a comparable quantity of body hair can be used. The term head hair refers exclusively to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test proceeds through four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves introducing a sample into the lab's system. This includes confirming the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and filling any additional data gaps not covered by an electronic chain of custody system.
Screening acts as a preliminary rapid assessment for substances of abuse. It's an economical way to eliminate drug use possibilities for most samples, but a positive screening result must be confirmed to hold up in court. Samples that exhibit a tentative positive in Screening necessitate further confirmation.
Should a sample show a tentative positive during Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are separated from the hair at a notably lower concentration compared to other methods (such as urine or oral fluid), which is why hair drug analysis is considered the most challenging method to conduct.
Confirmation of any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation as necessary. The entire lab process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation as well as the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While commonly termed "hair follicle tests", the analysis actually focuses on the hair strand, not 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.
