Accredited Drug Testing offers comprehensive hair follicle drug testing services in Merced, California. For those requiring a hair drug or alcohol test, Accredited Drug Testing is proficient in hair testing with facilities nationwide capable of conducting hair tests. You need 1.5 to 2 inches of hair from the head's crown, though body hair can often be used. Hair tests are analyzable for drugs, alcohol/ETG, or customized options.
In recent years, the frequency of hair follicle drug tests has increased, becoming the preferred method for many employers, courts, and Substance Abuse experts, who are opting for these over the traditional urine tests. Employers adhering to strict no-drug policies, judicial systems, and probationary agencies use hair follicle drug tests due to their significant benefit: an extended detection period of up to 90 days, coupled with a supervised collection process, making it nearly foolproof. Despite this, for detecting drug use within a recent 5-day period, the urine test remains the most precise option.

Hair analyses are increasingly regarded as an effective method for identifying drug and alcohol consumption. Hair retains a comprehensive record of alcohol and drug use by embedding biomarkers within the fibers of the growing hair. When collected close to the scalp, it offers an approximate three-month detection span for alcohol and drugs. Hair collection is straightforward, challenging to alter, and convenient for transport.
A 1.5-inch sample comprising roughly 200 hair strands (comparable in size to a #2 pencil) near the scalp provides 100mg of hair, which is optimal for examination and verification. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen of 150mg is advisable. Utilizing a jeweler’s scale for weighing is recommended. If scalp hair is inaccessible, a comparable amount of body hair might be used. By head hair, we mean scalp hair exclusively. Body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
There are four primary stages in the laboratory procedure for processing drug test outcomes: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into a lab’s framework. This encompasses verifying that the sample is securely sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry omitted by an electronic chain of custody system.
Screening performs an initial rapid assessment for drug abuse. Though Screening offers a budget-friendly method to negate drug usage in most samples, a positive screen must be validated to be legally acceptable. Samples preliminarily positive in Screening necessitate a secondary confirmation.
Should a sample be preliminarily positive during Screening, additional hair is extracted from the original specimen and prepped for Extraction. At this stage, drugs are extracted from hair at a substantially lower concentration compared to other methodologies (i.e., urine or oral fluid), rendering hair drug screening the most complex technique to execute.
Any positive screening outcome is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples preliminarily positive are washed ahead of confirmation if necessary. The comprehensive laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair specification and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Despite being sometimes called "hair follicle tests", the analysis is conducted on the hair strand rather than the follicle beneath 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.
