Accredited Drug Testing offers comprehensive hair follicle drug testing services in La Palma, California. If you're in need of a hair drug or alcohol screening, Accredited Drug Testing excels in hair testing, with testing centers located in all cities across the USA that can conduct a hair test. Typically, 1.5 to 2 inches of hair from the crown or body is required. Hair tests can analyze drugs and alcohol/ETG among other tailored testing options.
In recent times, drug testing methods have increasingly involved the hair follicle drug test. Many employers, judicial systems, and substance abuse experts now prefer a hair drug test rather than the traditional urine test. Hair follicle tests are employed by zero-tolerance employers, courts, and individuals under supervision. A key advantage of these tests is their extended detection period, usually up to 90 days, with results collected via an observed process, making them almost foolproof. However, for recent 5-day drug use detection, the urine test remains the best option.

Hair analysis is recognized as an effective instrument for uncovering drug and alcohol consumption. Hair captures a long-lasting record of alcohol and drugs by embedding biomarkers within the fibers of the hair shaft as it grows. When taken from near the scalp, hair can offer up to a 3-month detection period for substances like alcohol and drugs. Hair collection is straightforward, fairly resistant to tampering, and convenient for transport.
A sample measuring 1.5 inches, consisting of around 200 hairs (similar to the width of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional panels, or tests exceeding 10 panels, a specimen weight of 150mg is advised. We suggest weighing the hair on a jeweler’s scale. Should scalp hair be unavailable, a comparable quantity of body hair may be gathered. Note, when referencing head hair, it specifically means scalp hair. Body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The lab processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is first processed into the lab’s systems. It includes confirming the sample’s proper sealing and shipment, assigning it a random LAN (Laboratory Accessioning Number), and carrying out any extra data entry not included in an electronic chain of custody system.
Screening is a preliminary swift assessment for drugs of abuse. Although Screening is cost-efficient for ruling out drug usage in most samples, positive findings need confirmation before they are considered court-admissible. Samples showing a presumptive positive result during Screening must undergo secondary confirmation.
When a sample shows a presumptive positive in Screening, additional hair is extracted from the original sample for the Extraction stage. In this phase, drugs are retrieved from hair at considerably lower concentrations than in other testing methods (like urine or oral fluid), making hair drug screening among the most challenging methodologies.
Confirmation for any positive screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation as needed. The full lab process, from Accessioning to Confirmation, is monitored under both the CAP (College of American Pathologists) Hair classification and the certification to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While typically referred to as "hair follicle tests," the analysis is performed on the hair strand itself, not the hair follicle beneath the scalp.

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.
