In Mehlville, Missouri, Accredited Drug Testing offers all-inclusive hair follicle drug test services. If you require testing for drugs or alcohol using hair samples, our expertise in hair testing spans numerous Nationwide facilities ready to conduct these tests. Generally, 1.5 to 2 inches of head or body hair is needed for assessment. These tests examine drugs, alcohol/ETG, or other tailored testing demands.

Recently, drug testing increasingly involves hair follicle analysis. Employment sectors, judiciary systems, and Substance Abuse counselors now favor hair testing over traditional urine analysis. Employers with zero-tolerance policies, the courts, and probationary programs extensively utilize hair testing. Its major advantage is prolonged detection up to 90 days, collected through monitored procedures, and being nearly tamper-proof. However, urine tests remain superior in identifying drug use over the last 5 days.

What it is, How it works

Hair assessments have emerged as an effective means for identifying drug and alcohol consumption. Hair strands encapsulate a lengthy history of substance use by embedding biomarkers within the growing fibers. When acquired near the scalp, this method offers around a 3-month timeframe for detection of alcohol and drugs. Hair sampling is straightforward to collect, challenging to tamper with, and convenient to transport.

A 1.5-inch section comprising roughly 200 hair strands (similar in size to a standard pencil) near the scalp yields 100mg of hair, which is the preferred amount for screening and validation. For EtG extensions or evaluations exceeding 10 drug panels, 150mg of the substance is advisable. It's suggested to measure the specimen with a jeweler's scale. If scalp hair is inaccessible, a comparable quantity of body hair can be utilized. By "head hair," we mean hair from the scalp only, whereas "body hair" refers to all other forms (beard, underarm, etc.).

Process Overview

The core stages in the lab analysis of drug tests encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary input of a sample into the lab's framework. This step ensures proper sealing and shipping of the sample, assigns a unique LAN (Laboratory Accessioning Number), and fills any remaining data fields not covered by an electronic custody tracking system.

Screening provides an initial rapid test for illicit substances. While it serves as a budget-friendly method to dismiss drug usage for most samples, conclusive validation is necessary for legal proceedings. Any samples showing preliminary positive results in Screening call for further confirmation.

Upon a sample showing a preliminary positive in Screening, an extra portion of hair is taken from the original sample and readied for Extraction. In this phase, drugs are derived from hair at notably lower concentrations than other test types (e.g., urine or saliva), which renders hair testing the most intricate method to execute.

Verification of any initial positive findings is performed via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples showing preliminary positives undergo cleaning where necessary before Confirmation. The entire lab procedure from Accessioning to Confirmation is evaluated with compliance to both the CAP (College of American Pathologists) Hair designation and accreditation under ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug assessments can identify substance consumption for up to 90 days, as opposed to urine tests with shorter detection spans.
  • Resistance to manipulation: Hair drug testing is notoriously hard to manipulate, resulting in more reliable outcomes.
  • Trend analysis: It reveals drug use over an extended timeframe, beyond just recent consumption.

Limitations:

  • Inability to identify very recent use: Drugs become perceptible in hair only about 5-7 days post-use.
  • Expense: Hair drug assessments typically incur higher costs compared to other testing techniques.
  • Result variability: Elements like hair pigmentation and individual hair growth rates can sway the presence of drug traces in hair.

Clarification: Although often termed "hair follicle tests", these tests assess the hair strand itself, not the follicle beneath the scalp.
