Accredited Drug Testing offers comprehensive hair follicle drug testing services in Half Moon Bay, California. We are experts in this field, with centers across the country ready to administer these tests. Typically, you should have 1.5 to 2 inches of hair on the crown or elsewhere on your body. Hair tests can detect drugs, alcohol/ETG, and offer custom options.

The popularity of hair follicle drug tests has grown, often replacing standard urine tests. These tests are favored by employers, courts, and substance abuse professionals for their reliability. Hair tests support zero-tolerance policies and are critical for probationary oversight. The advantage lies in the extended detection period, observing use up to 90 days and minimizing tampering, though urine tests remain best for recent use within five days.

What it is, How it works

Hair analysis has gained recognition as a robust means for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug use by retaining biomarkers within the fibers of the developing hair strand. When collected adjacent to the scalp, hair offers a detection capability of up to roughly 90 days for alcohol and drugs. Hair is easy to gather, less prone to tampering, and convenient to transport.

A 1.5-inch segment of roughly 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp will provide 100mg of hair, which is the optimal quantity for evaluation and verification. For EtG, extended tests, and/or screenings beyond 10 panels, a 150mg sample is suggested. Using a jeweler’s scale for measurement is advised. If scalp hair is nonexistent, an equivalent quantity of body hair is suitable. By head hair, we specifically mean scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The key phases within the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary incorporation of a sample into a lab’s system. This phase involves checking that the sample was sealed and sent securely, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry absent in an electronic chain of custody system.

Screening entails an initial rapid assessment for drug abuse. Screening serves as an economical method for ruling out drug use in most samples, although a positive screen necessitates confirmation for courtroom admissibility. Samples with presumptive positives in Screening demand an additional confirmation.

In cases of presumptive positives during Screening, additional hair is extracted from the initial sample and gets ready for Extraction. In this phase, drugs are taken from hair at lesser concentrations than through other techniques (like urine or oral fluid), which makes hair drug screening the most demanding technique to execute.

Confirmation of any positive screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes washing before confirmation as required. The overall lab procedure from Accessioning to Confirmation gets evaluated according to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

  • Long detection period: Hair drug tests can discover drug use for as long as 90 days, contrasting with urine tests that have a shorter detection span.
  • Hard to manipulate: It is challenging to deceive a hair drug test, enhancing the reliability of the results.
  • Offers historical insight: It can represent a trend of drug use over time, not merely recent usage.

Limitations:

  • Incapable of detecting recent use: It requires around 5-7 days for drugs to be noticeable in hair.
  • Expense: Hair drug tests tend to cost more than other drug testing techniques.
  • Result variations: Variables such as hair color and personal differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Though often termed "hair follicle tests", the examination actually evaluates the hair strand, not the follicle beneath the scalp

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

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.

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.

Frequently Asked Questions

A hair follicle drug test analyzes a small sample of hair to detect a history of drug use over time.

It is frequently used for legal and court requirements, long-term monitoring, and high-trust workforce screening.
Standard hair drug testing typically reflects drug use over approximately a 90-day period, based on the length of hair collected at the time of testing. Longer hair can sometimes reflect a longer time frame, and extremely short hair can reduce that window.
Hair drug testing commonly screens for marijuana/THC, cocaine, opiates/opioids, amphetamines/methamphetamines, and PCP. In many cases, additional expanded panels may be requested to include other substances.
