In O'Fallon, Missouri, Accredited Drug Testing offers a comprehensive approach to hair follicle drug testing. Specializing in hair assessments for drugs and alcohol, our nationwide centers stand ready to conduct such tests. Generally, 1.5 to 2 inches of hair from the head's crown or an alternate body part is required. Testing can detect substances, alcohol/ETG, or accommodate other customized needs.

Recently, drug testing methods increasingly favor hair follicle examinations over urine analyses. Many organizations, legal systems, and substance abuse professionals now opt for hair tests. These tests cater to workplaces with strict anti-drug policies and legal bodies supervising probationers. The main advantage is a 90-day detection span, with observed sample collection minimizing manipulation risks. But for screening short-term use within 5 days, urine tests maintain higher precision.

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair retains a lengthy history of substance use by encasing biomarkers within its fibers as it grows. When cut close to the scalp, hair can offer nearly a 3-month window for detecting alcohol and other drugs. Hair is straightforward to collect, relatively resistant to tampering, and conveniently shippable.

A 1.5-inch sample consisting of roughly 200 hair strands (comparable to the size of a #2 pencil) nearest to the scalp delivers 100mg of hair, ideal for both screening and validation. For EtG, additional substances, and/or tests exceeding 10 panels, 150mg of hair is preferable. It is advisable to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, a similar quantity of body hair may be taken. Reference to head hair implies only scalp hair, while body hair pertains to all other types, including facial and axillary hair.

Process Overview

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

Accessioning is the introductory step of integrating a sample into a lab's system. This step validates that the sample was properly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and fulfills any additional data input not included via an electronic chain of custody.

Screening serves as an initial swift check for substances of abuse. While Screening offers a cost-efficient means to negate drug use in most samples, a positive outcome necessitates further validation for forensic acceptance. Samples showing presumptively positive results during Screening demand subsequent confirmation.

If Screening indicates a presumptive positive, more hair is drawn from the starting sample for the Extraction stage. Drugs are extracted from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), which accounts for the challenge of hair drug screening.

Confirmation of any positive screening findings is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples with presumptive positives undergo a wash before confirmation as required. The total lab process from Accessioning to Confirmation is inspected under 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 tests can ascertain drug consumption for up to 90 days, whereas urine tests have a more limited detection duration.
  • Resistance to manipulation: Cheating a hair drug test is considerably challenging, leading to more reliable outcomes.
  • Offers historical insight: It reveals a pattern of drug involvement over a timeframe, not merely recent usage.

Limitations:

  • Inability to detect recent usage: Drugs only become noticeable in hair after approximately 5-7 days.
  • Expense: Hair drug tests often incur greater costs compared to other testing approaches.
  • Result variability: Elements like hair color and individual hair growth differences can impact drug metabolite levels in hair.

Note: Commonly termed "hair follicle tests", the analysis focuses on the hair strand, not 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.
