In North City, Washington, Accredited Drug Testing provides comprehensive hair follicle drug testing. Specializing in hair tests, they offer services nationwide, ensuring you can access testing centers in any city. Typically, the use of 1.5 to 2 inches of hair from your head or body is needed. Hair testing can detect drugs, alcohol/ETG, and other substances through customized options.

Hair follicle testing is increasingly used over traditional methods, like urine tests, by employers, courts, and substance abuse professionals. For those with zero-tolerance drug policies, it offers an extended detection period of up to 90 days. It's a secure, tamper-resistant process that is difficult to modify. For recent drug use, within five days, urine tests remain more precise.

What it is, How it works

Hair assessments are increasingly recognized as an effective means for detecting drug and alcohol consumption. Hair captures a prolonged record of substances by enclosing biomarkers within the strands. When extracted near the scalp, it offers about a 90-day detection timeframe for different substances. Collecting hair is uncomplicated, relatively tamper-resistant, and easy to transport.

A 1.5-inch lock of roughly 200 hairs (about the size of a #2 pencil) closest to the scalp provides 100mg of hair, which is optimal for assessment and verification. For EtG additions and/or panels exceeding ten, a specimen of 150mg is advised. It's suggested to weigh the sample with a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be gathered. When discussing head hair, we are specifically referring to scalp hair only. Body hair encompasses all other hair types (facial, axillary, etc.).

Procedure Summary

The laboratory path to processing a drug test comprises four significant stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a sample into a lab’s system. This incorporates verifying the sample's proper seal and shipment, assigning a random LAN (Laboratory Accessioning Number), and entering any additional data absent from an electronic custody chain system.

Screening constitutes an initial rapid evaluation for substance abuse. Though Screening offers a budget-friendly means to rule out drug use in most samples, a screen yielding positive must be validated for legal acceptability. Samples presumptively positive in Screening necessitate secondary corroboration.

If a Screening stage indicates a presumptive positive, additional hair is extracted from the original sample for Extraction. In this phase, substances are withdrawn from hair at a lower concentration than other methods (e.g., urine or oral fluid), making hair drug screening the most intricate methodology to execute.

Verification of any positive screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing as needed before verification. The comprehensive lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criterion and the accreditation to ISO / IEC 17025 standards.

Merits of hair drug testing:

  • Extended detection span: Hair drug tests unveil substance use for as long as 90 days, compared to the shorter window of urine tests.
  • Hard to falsify: Tampering with hair drug tests is challenging, ensuring more precise outcomes.
  • Documents past consumption: It outlines a pattern of substance use over time, instead of just recent instances.

Drawbacks:

  • Can't detect recent consumption: Substances become noticeable in hair roughly 5-7 days post-ingestion.
  • Expense: Hair drug tests are typically pricier than alternative testing strategies.
  • Result fluctuations: Aspects like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Commonly termed as "hair follicle tests", the analysis targets the hair strand and not the beneath-the-scalp follicle.

Why Hair Follicle Testing Beats Urine Testing

In North City, WA, hair follicle testing surpasses traditional urine tests by offering enhanced detection accuracy and reliability. Unlike urine tests that detect recent usage, hair testing examines long-term patterns over a 90-day window, providing a comprehensive assessment of substance use. This extended detection period offers a holistic view of an individual’s history, making it a preferred choice.

Benefits of Hair Testing Over Urine:

  • Extended Detection: Captures a 90-day substance use history
  • Accuracy and Reliability: Minimizes errors related to recent minor usage
  • Ease of Collection: Simple and non-invasive process enhances convenience
Hair testing’s ability to detect varied substances with pinpoint accuracy stands as a testament to its superiority over urine tests.

Extended Detection Window

Hair follicle testing in North City, WA, offers an extended detection window of up to 90 days, significantly more than traditional methods. This period captures a comprehensive dataset of an individual’s drug use, offering employers invaluable insights into an applicant or employee’s substance history. It's particularly beneficial for roles requiring constant sobriety, as it reflects ongoing behaviors.

The capability to track long-term substance use ensures informed decisions, especially for employers and organizations prioritizing safety and compliance. By providing a fuller picture of an individual's drug history, hair testing enhances the vetting process, ensuring that only the right candidates pass through the recruitment funnel. Its longitudinal scope sets it apart as a decisive tool in maintaining workplace safety.

Tamper-Resistant Testing Method

In North City, WA, the tamper-resistant nature of hair follicle testing substantially reduces the risk of sample adulteration. By using hair samples instead of bodily fluids, the test eliminates the potential for manipulation, fostering reliable and unquestionable results. This integrity ensures that employers and legal entities can trust the outcomes for critical decisions.

The stringent collection process, consistent for every test subject, augments the tamper-resistant quality of hair follicle tests. This measure prevents the possibility of swapping or modifying samples, ensuring results are authentic reflections of an individual's drug usage. Hair testing, with its foolproof approach, stands as a stalwart ally in the quest for truth in drug testing.

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.
Yes. Hair drug testing is commonly used in court, probation, custody, and compliance matters because the collection process follows a documented chain of custody and the analysis is performed by a certified laboratory. Results are provided in a form that can be reviewed by legal and administrative authorities.
Yes. Individuals, parents, attorneys, employers, and probation programs can all request hair drug testing. A doctor's order is not required. Results are confidential and released only to the authorized requesting party.
Hair testing provides a longer look-back period than urine testing, making it useful when you need to demonstrate ongoing abstinence or identify repeated/recent substance use patterns over time rather than just recent exposure. It is frequently selected for legal, compliance, and custody-related documentation.
A small section of hair is cut by a trained collector in a discreet, controlled manner. The sample is sealed, documented, and sent to the laboratory under established chain-of-custody procedures so that the results can be defended if they are ever challenged.
