In Grimes, California, Accredited Drug Testing offers thorough hair follicle drug testing services. If you need drug or alcohol testing via hair analysis, we have the expertise and numerous centers nationwide to serve your needs. Requiring 1.5 to 2 inches of hair from the scalp, or body hair, our hair tests can check for various drugs, alcohol/ETG, and offer tailored testing solutions.
The hair follicle drug test method has gained more traction in recent years for drug testing purposes. Employers, courts, and Substance Abuse professionals increasingly choose hair drug tests over traditional urine tests. Employers with zero-tolerance policies, as well as courts overseeing probation, benefit from the extended detection period of up to 90 days offered by hair tests, conducted under observation and highly resistant to tampering. However, for detecting recent drug use within 5 days, urine tests remain the most accurate.

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. The hair preserves a prolonged record of alcohol and drug intake by capturing biomarkers within the strands as they grow. When collected near the scalp, hair can offer up to a three-month detection period for alcohol and drugs. Hair is straightforward to collect, somewhat hard to tamper with, and convenient to transport.
A 1.5-inch portion of approximately 200 hair strands (around the diameter of a #2 pencil) closest to the scalp provides 100mg of hair, the optimal sample for both screening and verification. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest weighing the sample on a jeweler’s scale. If scalp hair is absent, a similar amount of body hair can be obtained. Referring to head hair implies only the hair on the scalp, while body hair indicates all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result primarily involves the steps of Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary processing of a sample into a lab’s system. This entails confirming that the sample was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not handled by an electronic chain of custody system.
Screening entails an initial rapid assessment for drugs of abuse. Although Screening is an economical way to exclude drug use in most samples, a positive screen must be validated to be permissible in legal settings. Any samples that are preliminarily positive in Screening necessitate secondary confirmation.
If a sample yields a presumptive positive in the Screening phase, more hair is extracted from the original specimen and readied for Extraction. At this stage, drugs are extracted from hair at a substantially lower concentration than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to implement.
Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as required. The complete laboratory process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 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. 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.
