Accredited Drug Testing offers comprehensive hair follicle testing in San Ramon, California. Whether you need a drug or alcohol screen via hair sample, we specialize in this method and have centers across all U.S. cities ready to conduct the test. Adequate hair length—1.5 to 2 inches from the crown or body in most cases—is necessary. Hair analyses can check for drugs, alcohol/ETG, or tailored testing needs.
Over the years, hair follicle drug testing has increasingly become the method of choice for screenings. Employers, courts, and Substance Abuse professionals often prefer it over urine analysis. Hair tests are favored by entities with strict no-drug policies, including employers, judicial systems, and those managing probation. The key advantage is its extended detection window, up to 90 days, minimizing evasion, unlike urine tests which are optimal for recent drug use within 5 days.

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of the hair strand, hair offers an extended timeline of alcohol and drug intake. When hair is collected near the scalp, it can reveal drug and alcohol usage over the past three months. Hair is easy to collect, hard to tamper with, and simple to transport.
A sample measuring 1.5 inches from roughly 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the ideal amount for screening and confirmation. For tests involving EtG, additional panels, or those exceeding 10 panels, 150mg of the sample is suggested. We advise the specimen be weighed using a jeweler's scale. If scalp hair is unavailable, an equivalent quantity of body hair should be gathered. 'Head hair' specifically refers to scalp hair, while 'body hair' includes other types (facial, axillary, etc.).
Process Overview
The lab processing of drug tests comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first stage of processing a sample in a laboratory's system. It entails checking that the sample has been sealed and sent correctly, assigning a LAN (Laboratory Accessioning Number), and fulfilling any additional data recording not covered by an electronic chain of custody system.
Screening is a preliminary examination for drug abuse. Though screening allows for cost-effective elimination of drug use in most samples, any positive findings must be validated for court acceptance. Samples tentatively positive in screening necessitate further confirmation.
When a sample appears positive during the Screening phase, additional hair is taken from the initial specimen and prepped for Extraction. Here, drugs are extracted from hair in significantly lower concentrations compared to other methods (e.g., urine or saliva), making hair drug analysis the most challenging to conduct.
GC/MS, GC/MS/MS, or LC/MS/MS techniques are used to confirm any positive screening outcomes. Presumptive positives undergo washing prior to confirmation as needed. The full process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair category and the accreditation to ISO / IEC 17025 criteria.

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.
