Accredited Drug Testing offers complete hair follicle drug testing services in Bothell, Washington. When in need of a hair drug or alcohol test, Accredited Drug Testing excels in hair testing, with centers spread across all cities nationwide ready to conduct hair tests. Typically, 1.5 to 2 inches of hair on the scalp or body can suffice for most tests. Hair tests may be examined for drugs, alcohol/ETG, or tailored hair testing needs.

In recent times, drug testing methods have increasingly leaned toward hair follicle drug tests. More employers, courts, and substance abuse experts are opting for hair drug tests over conventional urine tests. These tests cater to employers with zero-tolerance drug policies, judicial systems, and those on probation. The main advantage of hair follicle drug tests is their extended drug detection window, generally up to 90 days, ensuring an observed collection procedure and making evasion nearly impossible. However, urine tests remain the most precise for screening drug use within the last five days.

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. The hair captures biological markers within the strands, providing a comprehensive timeline of substance use. When collected at the scalp's base, hair can offer up to a three-month detection period for drugs and alcohol. Hair samples are easy to gather, challenging to tamper with, and simple to send.

A sample measuring 1.5 inches in length with about 200 hair strands (approximately the thickness of a #2 pencil) near the scalp provides 100mg of hair, which is optimal for testing. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advised. Specimens should be weighed with a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair can be used. "Head hair" specifically refers to scalp hair, while "body hair" includes all other types (such as facial or axillary hair).

Process Overview

The laboratory processing of a drug test encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, the sample is first processed within the lab’s system by confirming proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and inputting any additional information not provided by an electronic chain of custody system.

Screening serves as an initial quick assessment for substances of abuse. Although Screening efficiently rules out drug use in most cases, any positive results must be authenticated to be valid in legal proceedings; thus, presumptive positive screenings necessitate further verification.

When a sample shows presumptive positivity during Screening, additional hair is derived from the original sample and readied for Extraction. This phase involves extracting drugs from hair at lower concentrations than other methods (like urine or oral fluid), highlighting the complexity of hair drug analysis.

The Confirmation phase uses GC/MS, GC/MS/MS, or LC/MS/MS for validating positive screenings. All samples marked as presumptive positive undergo washing before Confirmation if needed. Each phase, from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

  • Extended detection period: Hair drug testing can trace substance use for up to 90 days, unlike urine tests, which have a shorter detection timeframe.
  • Resistance to evasion: Hair drug tests are notably difficult to falsify, ensuring more reliable results.
  • Insight into past use: They offer a chronological pattern of drug use over time, not just recent usage.

Limitations:

  • Cannot identify recent intake: Drugs become traceable in hair approximately 5-7 days post-consumption.
  • Expense: Hair drug testing generally costs more than other drug testing methods.
  • Result variability: Factors such as hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Though termed "hair follicle tests", the actual analysis examines the hair strand rather than the follicle beneath the scalp.

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.
