Accredited Drug Testing offers comprehensive hair follicle drug assessments in Terrell Hills, Texas. If seeking a hair drug or alcohol evaluation, Accredited Drug Testing excels in such testing, with locations in cities nationwide equipped to perform these tests. Usually, 1.5 to 2 inches of hair from the crown or body can be used. Hair tests can check for drugs, alcohol/ETG, or other tailored testing choices.

Recently, drug testing approaches increasingly favor hair follicle drug assessments. Numerous employers, legal systems, and addiction professionals demand hair drug tests over traditional urine ones. Hair follicle tests are sought by zero-tolerance employers, courts, and those on probation. Their key benefit is a longer drug detection period, often up to 90 days, making it challenging to tamper with. However, for detecting drug use in the past 5 days, urine tests remain the most reliable.

What it is, How it works

Hair analysis is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair strands capture biomarkers within their growing fibers, providing a prolonged history of substance use. When hair is collected near the scalp, it offers a detection timeframe for alcohol and drugs of approximately three months. Hair collection is straightforward, difficult to tamper with, and convenient to transport.

Gathering a sample of 1.5 inches, equivalent to the width of a #2 pencil and consisting of about 200 strands, yields 100mg of hair, which is optimal for testing and verification. For EtG, additional analyses, and tests exceeding 10 panels, a sample size of 150mg is advised. It’s suggested to measure the sample using a jeweler’s scale. If scalp hair is not accessible, a comparable quantity of body hair can be used. The term head hair specifically denotes scalp hair only, whereas body hair encompasses all other hair types, including facial and axillary hair.

Process Overview

The laboratory analysis of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into the lab’s system. This process includes ensuring the sample was properly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and accomplishing any extra data entry that an electronic chain of custody system does not provide.

Screening is a preliminary check for drugs of abuse. This step is a cost-effective method to exclude drug usage in most samples, but a positive screening requires confirmation to be valid in legal settings. Samples screening as presumptively positive necessitate further confirmation.

For samples tagged as presumptively positive in Screening, additional hair is taken from the original sample and prepped for Extraction. Hair drug analysis extracts drugs at lower concentrations than other methods (e.g., urine or saliva), which is why hair testing is the hardest methodology to conduct.

Positive screening confirmations occur through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleaned before confirmation if needed. The complete process from Accessioning to Confirmation is monitored under the CAP (College of American Pathologists) Hair designation along with ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests can reveal drug usage for up to 90 days, unlike urine tests which have a shorter detection span.
  • Challenging to manipulate: Hair drug tests are hard to cheat, enhancing result accuracy.
  • Historical insight: Offers a timeline of drug consumption over a span, not merely recent usage.

Limitations:

  • Detects later use: Drugs become noticeable in hair after roughly 5-7 days.
  • Expense: Hair drug testing generally incurs higher costs than other methods.
  • Result discrepancies: Variables like hair color and personal hair growth differences may influence drug metabolite concentration in hair.

Note: Commonly labeled as "hair follicle tests," the analysis inspects the hair strand, excluding the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Terrell Hills, TX, surpasses traditional urine tests by accurately identifying substance use with greater reliability. While urine tests detect recent usage, hair tests offer a broader detection spectrum over 90 days, providing comprehensive insight into an individual's substance history, and its enhanced reliability makes it a favored choice for employers.

Extended Detection Window

Compared to other methods, hair follicle testing in Terrell Hills, TX, offers an extended detection window, identifying drug use over a longer period, often up to 90 days. This extended capability allows employers a deeper understanding of an individual's substance habits over time, offering a more complete picture of past behaviors.

Tamper-Resistant Testing Method
