Accredited Drug Testing provides comprehensive hair follicle drug assessments in Pharr, Texas. Whether you require a hair drug or alcohol analysis, our expertise lies in hair testing, with facilities available in cities nationwide to conduct such tests. Typically, 1.5 to 2 inches of hair from the scalp or body is needed. Hair tests can uncover substances, alcohol/ETG, or customized testing options.
Lately, methods for conducting drug assessments often incorporate hair follicle drug tests. Employers, courts, and specialists in Substance Abuse increasingly mandate hair testing over conventional urine tests. These tests are favored by zero-tolerance organizations, legal systems, and probationary cases. A key advantage of hair testing is its extended detection window for substance use, spanning up to 90 days and employing an observed collection method, making tampering nearly impossible. However, for detecting recent consumption within five days, urine tests remain most reliable.

Hair testing is now recognized as an effective technique for identifying drug and alcohol consumption. Hair retains a prolonged history of substance use by capturing biomarkers within the strands of growing hair. When taken near the scalp, hair can reveal substance use over an approximate 3-month period. Collecting hair is straightforward, somewhat challenging to tamper with, and convenient to transport.
A 1.5-inch segment of around 200 hair strands (similar to a #2 pencil) closest to the scalp provides 100mg of hair, which is the perfect quantity for both screening and confirmation. For EtG, additional tests, or those beyond 10 panels, 150mg of hair is advised. We suggest measuring the specimen with a jeweler's scale. If scalp hair is inaccessible, an equivalent quantity of body hair can be gathered. When mentioning head hair, we specifically mean scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The four essential steps in laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample enters the laboratory’s system for initial processing. This process ensures the sample was properly sealed and delivered, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry not managed by an electronic chain of custody.
Screening conducts an initial quick check for substances of abuse. Although Screening is an economical method to exclude drug use in most samples, a positive screening must be confirmed to be legally admissible. Samples that appear positive in Screening require additional confirmation.
If a sample is positive in the Screening phase, further hair is extracted from the original specimen for Extraction. Drugs are extracted at significantly lower concentrations than in other methods (e.g., urine or oral fluids), making hair drug screening more complex.
Confirmation of any positive screening result involves GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples that are presumptively positive undergo washing before confirmation as required. The entire laboratory process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although often called "hair follicle tests", the test analyzes the hair strand rather than the follicle beneath the scalp.
