In San Quentin, California, Accredited Drug Testing offers comprehensive hair follicle drug testing services. Our expertise in hair testing extends nationwide, with centers in every city capable of executing these tests. Generally, 1.5 to 2 inches of hair from the crown or body suffices for testing purposes. Hair tests are versatile, allowing analyses for drugs, alcohol/ETG, and other specialized options.
The trend in drug testing has shifted towards increased use of hair follicle tests. Employers, legal systems, and substance misuse specialists now often prefer these tests over traditional urine analyses. Hair follicle drug tests serve as a tool for those upholding strict no-drug-use policies and for monitoring probation compliance. Their chief advantage is an extended detection timeframe, up to 90 days, collected under observation, rendering them highly tamper-proof. However, urine tests remain optimal for ferreting out usage within the last five days.

Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. Hair captures a long-term record of drug intake by embedding biomarkers within the fibers of the hair as it grows. When hair is taken from near the head, it can reveal drug usage for a period of up to about three months. It's easy to gather, hard to tamper with, and simple to send.
A 1.5-inch section comprising roughly 200 hairs (approximately pencil-sized) nearest to the scalp equals 100mg of hair, which is perfect for both screening and confirmation. For tests like EtG, extras, or those over 10 panels, 150mg of the sample is advised. We advise measuring the sample on a jeweler's scale. If scalp hair isn't available, an equivalent amount of body hair may be used. Head hair refers solely to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four core stages in the lab processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample enters the laboratory’s system. This step entails ensuring the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry not included in an electronic chain of custody.
Screening is a preliminary rapid assessment for drugs. Although Screening effectively rules out drug use in most samples, a positive result must be validated to be court-acceptable. Any samples that test positive in Screening require further verification.
When a sample tests positive in the Screening phase, additional hair is taken from the primary sample and readied for Extraction. Here, drug substances are pulled from hair at concentrations far lower than those seen in other methods (urine or oral fluid), hence making hair drug testing the most challenging method.
Any positive findings from Screening undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed if necessary before confirmation. The full lab procedure from Accessioning to Confirmation is inspected following both the CAP (College of American Pathologists) Hair code and ISO / IEC 17025 accreditation norms.

Note: Commonly called "hair follicle tests", the test examines the hair strand, not the follicle underneath the scalp

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. 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. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.
The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
