Accredited Drug Testing offers comprehensive hair follicle drug tests in Kenmore, Washington. When you require a hair drug or alcohol test, Accredited Drug Testing is an expert in this method, providing services through testing locations across all major cities Nationwide. A minimum of 1.5 to 2 inches of hair from the crown or body is typically needed. Hair samples are analyzed for drugs, alcohol/ETG, or other tailored testing options.

In recent times, the preference for drug screening methods has shifted towards hair follicle tests. These tests are increasingly being mandated by employers, legal systems, and Substance Abuse experts as a substitute for the conventional urine test. Hair follicle testing is favored by employers with strict drug-free policies and by courts for individuals on probation, due to its extended drug detection period of up to 90 days, its supervised collection, and its high resistance to manipulation. However, urine tests remain more precise for recent drug use within the past 5 days.

What it is, How it works

Hair testing is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair offers an extended timeline of drug and alcohol exposure by encasing biomarkers within the matrix of the hair as it grows. Proximal hair samples, taken from near the scalp, can retrospectively analyze drug and alcohol use over a span of up to three months. Hair collection is straightforward, challenging to tamper with, and simplifies logistics for shipping.

Collecting a 1.5-inch sample comprising roughly 200 strands next to the scalp equates to about 100mg of hair, which is the ideal sample size for screening and confirmatory tests. For tests such as EtG, additional panels, or those exceeding 10 panel tests, a 150mg sample is preferable. It is advised to weigh the specimen using a jeweler's scale. If scalp hair isn't obtainable, an equivalent mass of body hair can be used. Reference to head hair pertains solely to scalp hair, while body hair encompasses all other kinds (e.g., facial, axillary).

Process Overview

The laboratory processing of a drug test result encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially entered into the laboratory system. This step ensures that the sample was correctly sealed and transported, assigns a random Laboratory Accessioning Number (LAN), and completes necessary data entry not covered by an electronic chain of custody.

Screening acts as a preliminary assessment to identify substances of abuse. Although it is an economical approach to exclude drug consumption in numerous samples, only confirmed positive results hold legal credibility. Presumptively positive samples necessitate secondary validation.

Presumptive positive results from Screening lead to further hair extraction from the initial specimen for the Extraction stage. Drugs are isolated from the hair at concentrations much lower than those in alternative testing methods (e.g., urine, oral fluid), which underscores the complexity of hair drug screening.

Confirmation of any presumptive positive findings is executed through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating a preliminary positive are cleansed prior to confirmation if deemed necessary. The entire Accessioning through Confirmation procedure adheres to regulatory reviews, specifically by the CAP (College of American Pathologists) Hair accreditation and the ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug assays can determine drug use over a 90-day duration, surpassing the shorter detection scope of urine tests.
  • Resistance to tampering: The likelihood of deceit in hair drug assessments is minimal, thus ensuring accuracy in results.
  • Historical insight: It provides a chronological account of drug use, distinguishing between persistent and recent consumption.

Limitations:

  • Inability to detect immediate use: Drugs generally become evident in hair only after 5-7 days.
  • Expense: Hair drug tests usually incur higher costs compared to other testing techniques.
  • Result variability: Diversities in hair color and personal hair growth rates can influence drug metabolite levels within the hair matrix.

Note: Commonly referred to as "hair follicle tests," the procedure actually examines the hair shaft, not the follicle beneath the skin.

Why Hair Follicle Testing Beats Urine Testing

In Kenmore, WA, hair follicle testing stands out as a highly effective alternative to traditional urine tests. Its superior detection capabilities provide a more complete picture of an individual's drug use history.

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.

Frequently Asked Questions

A hair follicle drug test analyzes a small sample of hair to detect a history of drug use over time. Because drug metabolites are incorporated into hair as it grows, this method can show patterns of use instead of just recent exposure. 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.
Yes. If the donor's head hair is too short or unavailable, body hair may be collected as an alternative. The collector will document the source of the sample. This allows testing even for individuals with recently cut or shaved head hair.
