Accredited Drug Testing in Port Isabel, Texas offers comprehensive services in hair follicle drug testing for substances like drugs and alcohol/ETG. With testing centers spread across all cities nationwide, we specialize in hair tests requiring 1.5 to 2 inches of hair, which can be conducted on both head and body hair, offering customized options.
Recent trends in drug testing favor hair follicle tests over traditional urine tests, preferred by employers, courts, and substance abuse professionals. This method supports zero-tolerance policies due to its extended detection window of up to 90 days, and secure, observed sample collection. Nonetheless, for recent drug use within five days, urine tests remain more reliable.

Recognized as a robust approach for detecting alcohol and drug use, hair testing presents a long-term overview of substance intake by locking biomarkers in the strands of growing hair. When drawn near the scalp, hair samples offer nearly a 3-month detection range for alcohol and other drugs. Collecting hair is straightforward, relatively resistant to tampering, and convenient to transport.
A hair sample measuring 1.5 inches and comprising approximately 200 strands near the scalp (about the width of a standard pencil) provides 100mg, the preferred sample size for analysis. For EtG, additional tests, or those exceeding 10 panels, 150mg of hair is advisable. It's best to measure the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent volume of body hair can be procured. When discussing head hair, we exclusively mean scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The drug testing laboratory process encompasses four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample enters into the laboratory’s system. This step confirms the sample was sealed and transported correctly, attaches a random LAN (Laboratory Accessioning Number), and completes any supplementary data input omitted by an electronic chain of custody system.
Screening is a preliminary assessment to identify drugs of abuse. This cost-efficient method helps rule out drug consumption in most samples, yet a positive result from Screening requires confirmation to be deemed valid in legal contexts. Any samples that test positively during Screening must undergo additional confirmation.
If a sample tests presumptively positive in the Screening phase, extra hair is extracted from the original sample and readied for Extraction. During Extraction, drugs are withdrawn from hair at far lower concentrations than in other methods (such as urine or oral fluid), underscoring why hair drug screening is exceptionally challenging.
Positive results from Screening are validated through GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating a presumptive positive are cleaned before Confirmation when necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is subjected to review under both the CAP (College of American Pathologists) Hair designation and in compliance with ISO / IEC 17025 standards.
