In Oakville, Missouri, Accredited Drug Testing provides comprehensive hair follicle testing services. Whether you require drug or alcohol testing via hair analysis, our specialists are equipped to perform these tests nationwide. With hair length of 1.5 to 2 inches, results can cover various substances, including drugs, ETG/alcohol, or other tailored testing needs.

Recently, there's been a notable shift towards hair follicle testing for drugs. Employers, judiciary systems, and substance abuse experts often prefer this method over urine tests. Hair testing is favored by entities with strict no-drug policies due to its extended 90-day detection capability, closely monitored collection process, and near-impossibility of tampering. However, urine tests remain effective for recent drug use within five days.

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. The history of alcohol and drug intake is stored long-term in hair fibers by embedding biomarkers within the growing strand. When samples are taken close to the scalp, they offer up to an approximate three-month detection period for substances. The process of collecting hair is straightforward, relatively tamper-proof, and convenient to transport.

A 1.5-inch section containing approximately 200 hair strands (comparable to a #2 pencil's diameter), when collected near the scalp, yields 100mg of hair—ideal for both initial screening and confirmation. For EtG, extra tests, or panels exceeding ten types, 150mg of hair should be gathered. Utilizing a jeweler's scale is suggested to weigh the hair accurately. If scalp hair is unavailable, an equivalent volume of body hair can substitute. Reference to head hair strictly means scalp hair, whereas body hair encompasses other types (such as facial or axillary hair).

Process Overview

The laboratory procedure to generate drug test results comprises four essential stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step of integrating a sample into a lab’s tracking system. This involves ensuring the sample's seal and delivery were intact, generating a unique LAN (Laboratory Accessioning Number), and inputting any necessary data not covered by an electronic custody system.

Screening serves as the initial swift assessment for detecting substance abuse. Although Screening is economical and serves to eliminate drug use for most samples, a positive outcome requires subsequent confirmation to be legally viable. Any samples flagged as presumptively positive at this phase warrant further confirmation.

For samples assessed as potentially positive during Screening, additional hair from the original sample is utilized for the Extraction phase. At this stage, the drug compounds are isolated from the hair at considerably lower levels than through other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening in comparison to other methodologies.

Positive results from screenings are confirmed through techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Any samples suspected to test positive are prepped by washing prior to the confirmation process. The full testing workflow—from Accessioning through Confirmation—is subjected to both the CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation reviews.

Advantages of hair drug testing:

  • Extended detection period: Hair tests identify drug usage up to 90 days, unlike the shorter window offered by urine tests.
  • Hard to manipulate: The reliability of hair drug testing is reinforced as it is challenging to falsify results.
  • Offers pattern insight: It delivers a comprehensive overview of usage patterns, rather than just recent activity.

Limitations:

  • Ineffective for recent usage: It typically takes about 5-7 days for the presence of drugs to manifest in hair.
  • Expense: Hair drug testing generally incurs higher costs compared to other testing methods.
  • Result variations: Factors such as individual hair color and growth rates can impact the metabolite concentration found in hair.

Note: Although often referred to as "hair follicle tests," the analysis itself focuses on the hair strand and not the follicle beneath the scalp.
