Accredited Drug Testing provides comprehensive hair follicle drug screening in Westwood, Missouri. Whether you require testing for drugs or alcohol, our specialization in hair sampling is notable, and we host centers nationwide to conduct such tests. Typically, 1.5 to 2 inches of hair is necessary, whether from the scalp or body. Hair tests offer analyses for drugs, alcohol/ETG, and other tailored testing variations.

Recently, the approach to drug screening increasingly incorporates the hair follicle drug method. Many employers, judicial entities, and substance misuse experts are choosing this over traditional urine screenings. Hair tests are favored by zero-tolerance employers, courts, and probationary protocols due to their extensive detection range, approximately 90 days, observed sampling, and resistance to tampering. Yet, urine tests remain more precise for detecting usage within the last five days.

What it is, How it works

The adoption of hair testing has risen due to its effective detection capabilities for drug and alcohol consumption. Hair acts as a durable record of substance intake by capturing biomarkers within the fibers of growing strands. When taken near the scalp, hair can reveal drug and alcohol use for up to three months. Hair collection is straightforward, challenging to tamper with, and easy to transport.

A 1.5-inch portion consisting of about 200 hair strands (roughly resembling a #2 pencil) closest to the scalp equates to 100mg of hair, optimal for screening and confirmation purposes. For EtG, additional tests, and/or tests exceeding 10 panels, a 150mg sample is advised. We suggest weighing the sample using a jeweler’s scale. If scalp hair isn’t available, an equivalent amount of body hair is acceptable. References to head hair mean scalp hair only. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The lab processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary processing of a sample into a laboratory’s framework. This step ensures the sample was sealed and dispatched correctly, a LAN (Laboratory Accessioning Number) is assigned, and any other data not supplied by an electronic chain of custody is entered.

Screening conducts an initial brief check for substance abuse. Although Screening effectively dismisses drug usage for most samples, positive results need confirmation to hold up in legal contexts. Any presumptive positives in Screening must undergo additional verification.

Should a sample test positive during Screening, additional hair is taken from the original sample for Extraction. This stage extracts drugs from hair at considerably lower concentrations than other methods (e.g., urine or oral fluid), signifying the complexity of hair drug screening.

Confirmation of positive screening outcomes employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumed positive samples are cleansed before confirmation if needed. The full lab process, from Accessioning to Confirmation, undergoes review in accordance with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug testing can identify drug use for up to 90 days, whereas urine tests typically have a shorter detection range.
  • Difficult to deceive: Cheating a hair drug test is extremely challenging, leading to more reliable results.
  • Offers historical insight: It reveals patterns of substance use over time, rather than just recent consumption.

Limitations:

  • Unable to detect current use: Drugs become detectable in hair after about 5-7 days.
  • Expense: Hair drug testing tends to be pricier compared to other testing methods.
  • Outcome variability: Factors like hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although often termed "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Westwood, MO, hair follicle testing stands out as a superior option compared to traditional urine testing. Hair tests offer a much longer detection window, capturing substance use history up to 90 days, while urine tests are limited to recent usage. This makes hair testing a more effective tool for identifying patterns of drug use.

The significant advantage of hair follicle testing lies in its resistance to manipulation and its heightened detection capabilities. Unlike urine tests, which are susceptible to tampering, hair tests provide a more secure and trustworthy assessment of an individual's substance use history.

Extended Detection Window

Hair follicle testing in Westwood, MO boasts an extended detection window for substance use. Unlike other testing methods, hair analysis can reveal drug use over a period of up to 90 days, offering employers a detailed view of an individual's substance history.

This prolonged detection capability is invaluable for employers who need a thorough understanding of an applicant’s or employee’s past substance use. By choosing hair follicle testing, they gain insight into long-term patterns rather than just recent use.

Tamper-Resistant Testing Method

Hair follicle tests in Westwood, MO provide a tamper-resistant method of detecting substance use. This testing approach drastically reduces the chance of sample adulteration, as hair samples are less susceptible to manipulation compared to urine samples.

The robustness of hair follicle testing ensures that results remain credible and valid. Organizations and courts can rely on the accuracy and unaltered nature of these tests, contributing to more reliable accountability measures.

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.
