Accredited Drug Testing offers comprehensive hair follicle drug testing in Knippa, Texas. If a hair-based drug or alcohol test is needed, Accredited Drug Testing excels in this area, providing facilities in all cities nationwide capable of performing such tests. Generally, 1.5 to 2 inches of hair from the crown or body can be analyzed. Hair tests can detect drugs, alcohol/ETG, or other tailored hair testing services.

Recently, hair follicle drug tests have become a prevalent choice for drug screening. Numerous employers, courts, and substance abuse experts prefer hair tests over standard urine tests. Such tests are chosen by employers with zero-tolerance policies, judicial systems, and those on probation. Their main advantage lies in their extended detection period, covering drug use up to 90 days, with observed collection processes that minimize tampering. Yet, urine tests remain superior for detecting use within the last 5 days.

What it is, How it works

The use of hair testing has emerged as a formidable method for identifying drug and alcohol consumption. By embedding biomarkers within the strands, hair offers a prolonged record of substance use. When trimmed near the scalp, hair can present a detection period extending up to three months for alcohol and other substances. The collection of hair is straightforward, somewhat resistant to tampering, and easy to transport.

An ideal sample size for both screening and confirmation involves 1.5 inches of hair, consisting of about 200 strands (comparable in diameter to a #2 pencil), providing approximately 100mg of hair. For tests involving EtG, additional panels, or those extending beyond 10 panels, 150mg of the sample is advisable. It is suggested to weigh the sample with a jeweler's scale. If scalp hair is not available, an equivalent amount of body hair can be utilized. When mentioning head hair, we focus exclusively on scalp hair. Body hair denotes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test outcomes follows four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary phase where a sample undergoes initial integration into a lab system. This encompasses confirming the sample's secure sealing and transport, generating a random LAN (Laboratory Accessioning Number), and completing any supplemental data input that an electronic chain of custody system may lack.

The Screening phase entails a swift review for substance abuse, serving as an economical method to dismiss drug use in most samples. However, a positive Screening result necessitates a follow-up confirmation for legal acceptance. Any samples with presumptive positive findings during Screening require an additional confirmation step.

For any samples showing presumptive positives during the Screening phase, more hair is extracted from the original specimen to set up for Extraction. During this step, drugs are removed from hair at considerably lower concentrations compared to other methods (such as urine or oral fluid), thereby marking hair drug screening as the most challenging technique.

Final Confirmation for any positive screening involves GC/MS, GC/MS/MS, or LC/MS/MS testing methods. All samples with presumptive positive readings undergo washing if required before confirmation. The comprehensive review chain from Accessioning to Confirmation is conducted under the CAP (College of American Pathologists) Hair standard and adheres to ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests can determine drug use for up to 90 days, in contrast with urine tests which offer a shorter detection span.
  • Resistant to deceit: Cheating a hair drug test is extremely challenging, which enhances the credibility of results.
  • Historical insights: It provides an extended pattern of drug use over time, unlike tests that only reflect recent usage.

Limitations:

  • Incapability to detect recent ingestion: Drugs become detectable in hair approximately 5-7 days after use.
  • Expense: Generally, hair drug tests incur higher costs compared to other testing approaches.
  • Results variability: Factors such as hair color and personal hair growth variations can influence the concentration of drug metabolites in hair.

Note: Often dubbed as "hair follicle tests", the examination focuses on the hair strand itself rather than the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Knippa, TX, highlights distinct advantages over traditional urine tests. The primary benefit lies in the enhanced detection accuracy, making it a preferred choice for zero-tolerance policies.

Extended Detection Window
