Accredited Drug Testing offers comprehensive hair follicle drug screening in Villanova, Pennsylvania. If a hair-based drug or alcohol test is required, Accredited Drug Testing provides expertise in this area, with centers available in cities across the nation to conduct hair analyses. Typically, 1.5 to 2 inches of head or body hair is needed. Hair tests can screen for drugs, alcohol/ETG, or be customized for other testing purposes.
In recent years, hair follicle drug testing has become more prevalent in drug testing methods. Many employers, courts, and substance abuse specialists now favor hair tests over standard urinalysis. Businesses with zero-tolerance policies, courts, and probation services frequently choose hair follicle tests. The main advantage is their detection window for drug use, which extends up to 90 days, is conducted under supervision, and is nearly foolproof. For detecting drug use in the past 5 days, urine tests remain the most accurate option.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Utilizing hair tests has gained recognition as a robust method for detecting drug and alcohol consumption. Hair offers an extended historical view of alcohol and drug use due to the entrapment of biomarkers within the fibers of the hair as it grows. When hair is obtained close to the scalp, it can provide a detection period of up to about 90 days for alcohol and other substances. It's straightforward to collect, fairly challenging to tamper with, and convenient to send.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, an ideal amount for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a specimen of 150mg is advised. We suggest using a jeweler’s scale for weighing the specimen. If scalp hair is not available, an equivalent amount of body hair can be used. 'Head hair' refers solely to scalp hair, whereas 'body hair' includes all other types (such as facial or axillary).
Process Overview
The laboratory processing of a drug test result encompasses four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial entry of a sample into a laboratory's system, which involves checking that the sample was sealed and transported correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.
Screening involves a preliminary swift check for substances of abuse. Although Screening is cost-efficient for eliminating drug presence in the majority of samples, any positive findings need confirmation to be legitimate for court proceedings. All samples indicating presumptive positivity in Screening must undergo a secondary confirmation.
If a sample indicates a presumptive positive result in the Screening step, additional hair is drawn from the original sample and readied for Extraction. Here, drugs are extracted from hair at much lower concentrations than other methods (like urine or oral fluids), making hair drug screening the most complex methodology to carry out.
Confirmation for any positive Screening result is performed using either GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation as required. The complete laboratory process from Accessioning to Confirmation is inspected according to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Limitations:
Note: Though commonly called "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.

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.
