Hair testing is recognized as an effective method for detecting drug and alcohol usage. It offers an extended timeline by capturing biomarkers within the strands of hair as it grows. When hair is taken near the scalp, it can present a detection window of up to 3 months for drugs and alcohol. Gathering hair is straightforward, relatively hard to tamper with, and convenient to transport.
A sample measuring 1.5 inches, consisting of around 200 strands (comparable in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is perfect for analysis. For EtG, additional tests, or panels beyond 10, a 150mg sample is advised. Using a jeweler’s scale to weigh this sample is recommended. If scalp hair isn't available, a similar amount of body hair can be used. "Head hair" references scalp hair only, while "body hair" includes any other body areas (such as facial, axillary).
Process Overview
The lab procedure for reviewing drug test results consists of Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to initially entering a sample into the lab's system. This process ensures the sample is sealed and shipped correctly, assigns a LAN (Laboratory Accessioning Number), and includes any additional input not provided by digital chain of custody records.
Screening is a preliminary check for drugs. While it's an efficient way to eliminate drug use in most samples, a positive test must be confirmed for legal admissibility. Any samples with potential positives in Screening need a follow-up confirmation.
If a sample tests positive in Screening, extra strands are taken from the initial sample and prepared for Extraction. In this step, drugs are pulled from hair at much lower concentrations than through other substances (like urine or oral fluid), making hair testing a complex method.
Confirmation of positive results occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All potential positive samples are cleansed before confirmation as needed. The full lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair specifications and ISO / IEC 17025 certification standards.

Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
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.
