Accredited Drug Testing offers extensive hair follicle drug testing services in Tukwila, Washington. If you're seeking a hair drug or alcohol analysis, we excel in hair testing with centers in all major cities across the U.S. Typically, you need 1.5 to 2 inches of hair on your head or body for this test. Hair tests can screen for drugs, alcohol/ETG, or other tailored options.
In recent times, drug testing methods have increasingly incorporated hair follicle tests. Numerous employers, judicial bodies, and addiction specialists are preferring hair drug tests over traditional urine analyses. Employers with strict drug policies, courts, and probation officers employ these tests as they offer an extended detection window of up to 90 days, are collected under supervision, and are highly resistant to cheating. However, urine tests remain most precise for detecting drug usage within the past five days.

Hair analysis is regarded as an effective instrument for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug intake by embedding biomarkers within the strands during growth. Hair gathered near the scalp can yield a detection timeframe of up to roughly three months for alcohol and drugs. The collection process is straightforward, manipulation is challenging, and the specimen is simple to transport.
A 1.5-inch piece consisting of about 200 hair strands (approximating the diameter of a #2 pencil) closest to the scalp provides around 100mg, which is the optimal quantity needed for testing and validation. For EtG, additional tests, and analyses exceeding 10 panels, a specimen size of 150mg is suggested. It's advisable to measure the specimen using a jeweler's scale. Should scalp hair not be available, equivalent body hair may be used. The term 'head hair' signifies solely scalp hair. 'Body hair' encompasses all other hair types (e.g., facial, axillary).
Process Overview
There are four key phases in the laboratory procedure for processing a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves initially entering a sample into a laboratory system. This step includes ensuring the sample’s seal and shipping integrity, generating a random LAN (Laboratory Accessioning Number), and completing any missing data not covered by an electronic chain of custody.
Screening offers a preliminary assessment for substance abuse. Although Screening is an economical method for eliminating drug usage in the bulk of samples, a positive result must be verified for it to be legally valid. Specimens that test as presumptively positive in Screening require a further confirming test.
For samples that result in a presumptively positive outcome at Screening, additional hair is taken from the initial collection for Extraction. Here, substances are extracted from hair at considerably lower concentrations than with other techniques (e.g., urine or oral fluids), lending to hair drug testing’s complexity.
Confirmation of any positive screening result is executed through methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive specimens undergo washing before confirmation if needed. This entire laboratory sequence, from Accessioning through Confirmation, adheres to the CAP (College of American Pathologists) Hair classification and complies with ISO/IEC 17025 standards.

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.
