In Cross Keys, Missouri, Accredited Drug Testing offers comprehensive hair follicle drug assessments. Whether you're seeking hair drug or alcohol testing, our expertise lies in this area, with centers nationwide. Typically, 1.5 to 2 inches of hair from your head or body are used. Our hair tests can check for drugs, alcohol/ETG, or provide other tailored options.

Over recent years, drug testing methods have increasingly incorporated hair follicle tests as opposed to standard urine tests. A growing number of employers, judicial systems, and substance abuse counselors prefer this method. From workplaces with zero-tolerance to courts and probation individuals, the main advantage is the extended detection window of up to 90 days, with observed sampling that is challenging to tamper with. However, for identifying very recent drug use, urine testing remains highly accurate.

What it is, How it works

Hair analysis has gained recognition as an effective means for identifying drug and alcohol consumption. Hair acts as a repository of alcohol and drug markers by embedding these in the strands as they grow. When gathered near the scalp, hair offers up to nearly a 3-month timeframe for detecting alcohol and drugs. Hair is straightforward to collect, relatively resistant to tampering, and simple to transport.

A 1.5-inch hair segment of approximately 200 strands (comparable to the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal amount for both initial testing and verification. For EtG, supplemental tests, and/or evaluations exceeding 10 panels, a 150mg sample is advised. The specimen should be weighed on a jeweler’s scale. If scalp hair is absent, an equal quantity of body hair may be taken. When mentioning head hair, it specifically refers to scalp hair. Body hair includes all non-scalp hair types (facial, axillary, etc.).

Process Overview

The four key stages in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary integration of a sample into the laboratory’s framework. This comprises confirming the sample's seal and secure shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not available through an electronic chain of custody.

Screening offers an initial, rapid assessment for drug abuse. Although cost-effective for ruling out drug use in most samples, a positive result from Screening requires confirmation for legal admissibility. All samples testing presumptively positive in Screening demand a follow-up confirmation.

If the Screening phase indicates a presumptive positive, more hair is extracted from the original sample for preparation in the Extraction stage. Drugs are isolated from hair at very low concentrations, making hair testing one of the most challenging procedures compared to other methods like urine or saliva testing.

Confirmation of any positive Screening findings occurs through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. The complete laboratory process from Accessioning to Confirmation is inspected both under CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests reveal drug usage up to 90 days, unlike urine tests with shorter detection periods.
  • Hard to manipulate: Hair drug testing is resistant to tampering, ensuring more precise results.
  • Historical usage information: It records patterns of drug use over time, beyond recent consumption.

Limitations:

  • Inability to detect recent use: Drugs require roughly 5-7 days to become detectable in hair.
  • Expense: Generally costlier than other drug testing techniques.
  • Result variability: Factors such as hair color and personal differences in hair growth can impact drug metabolite concentration in hair.

Note: Although termed "hair follicle tests", the test actually evaluates the hair strand and not the underlying hair follicle.

Why Hair Follicle Testing Beats Urine Testing

In Cross Keys, MO, hair follicle testing surpasses urine testing due to superior detection capabilities and steadfast reliability. While both serve as drug detection tools, hair testing excels by identifying drug use over an extended period, often up to 90 days.

    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.
