Accredited Drug Testing provides comprehensive hair follicle drug testing services in Los Fresnos, Texas. If you're looking for a hair drug or alcohol test, we specialize in hair testing and have centers across all U.S. cities capable of conducting these tests. Generally, 1.5 to 2 inches of hair from your crown or body is required. Hair tests can detect drugs, alcohol/ETG, or offer other tailored testing options.

In recent times, drug testing frequently involves a hair follicle drug test. Many workplaces, legal systems, and substance abuse experts now prefer hair tests to standard urine tests. Hair follicle tests are favored by employers with strict drug policies, courts, and those overseeing probation. The key advantage is its longer detection span for drugs, reaching up to 90 days, and using a monitored collection method, it's nearly tamper-proof. Yet, when detecting recent drug use within five days, urine tests remain highly accurate.

What it is, How it works

Recognized for its efficacy, hair testing serves as a potent method for identifying the use of drugs and alcohol. Hair captures a prolonged timeline of substance use by embedding biomarkers within the strands as they grow. When snipped near the scalp, hair reveals a detection period extending nearly 90 days for both alcohol and other substances. Collecting hair is straightforward, difficult to tamper with, and convenient for shipping.

A snippet of 1.5 inches, approximately 200 strands (comparable to a #2 pencil), taken nearest to the scalp provides a 100mg sample, optimal for both screening and confirmation. For EtG, additions, and/or tests exceeding 10 panels, a 150mg specimen is advisable. It is recommended to measure the sample with a jeweler's scale. In the absence of scalp hair, an equivalent quantity of body hair is suitable. References to head hair pertain solely to scalp hair, while body hair includes all other types (facial, axillary, etc.).

Process Overview

The drug test result process entails four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial integration of a sample into the laboratory system. This step ensures that the sample’s seal and shipment are intact, assigns a random LAN (Laboratory Accessioning Number), and addresses any additional data entry absent from an electronic chain of custody.

Screening offers a preliminary, rapid assessment for drug abuses. While Screening is a cost-effective measure to dismiss drug consumption in most cases, a positive result warrants confirmation for legal admissibility. Presumptively positive Screening samples necessitate a secondary verification.

Should a sample yield a presumptive positive in the Screening phase, additional hair is extracted from the primary sample for the Extraction process. This phase involves deriving drugs from hair at significantly lower concentrations than alternative methods (e.g., urine or oral fluid), explaining the challenge of hair drug testing.

Confirmation of positive results is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positives are cleansed prior to confirmation when needed. The comprehensive lab process ranging from Accessioning to Confirmation is subject to review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extensive detection period: Hair drug tests can identify drug application for a duration of up to 90 days, whereas urine tests lack such an extended detection timeframe.
  • Hard to manipulate: As tampering with a hair drug test is notably challenging, the results are deemed more reliable.
  • Reveals past consumption: It can outline a timeline of drug consumption over an extended period, beyond just recent usage.

Limitations:

  • Incapable of identifying recent use: Drugs become noticeable in hair approximately 5-7 days post-use.
  • Expense: Hair drug testing typically incurs higher costs compared to alternative drug testing techniques.
  • Diverse outcomes: Elements such as hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Often mischaracterized as "hair follicle tests", the analysis focuses on the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
