In India, Texas, Accredited Drug Testing offers comprehensive hair follicle drug testing services. Specializing in this type of testing, they provide hair drug and alcohol testing across the nation with centers in various cities. Usually, 1.5 to 2 inches of hair from the scalp or body is necessary for testing. Hair analysis can detect drugs, alcohol/ETG, or be tailored for specific testing needs.
Over the years, hair follicle drug testing has increasingly become a standard procedure for drug screening. More employers, courts, and substance abuse professionals now choose hair tests over typical urine tests. This is favored by employers enforcing strict no-drug policies, judicial authorities, and probation supervisors. The key advantage is its extended detection time, generally spanning 90 days, with results from supervised sample collection. Conversely, for detecting recent drug use within the past five days, urine tests remain the most effective.

Utilizing hair testing is increasingly recognized as an effective means for identifying alcohol and drug usage. Hair captures biomarkers within its growing strands, offering a comprehensive history of substance intake. A sample taken near the scalp can reveal drug and alcohol presence over a timeframe of three months. Hair collection is straightforward, relatively tamper-proof, and convenient to transport.
Collecting 1.5 inches of hair, approximately 200 strands (comparable to the thickness of a #2 pencil), from near the scalp results in 100mg, which is the preferred amount for testing. For EtG and any assessments exceeding ten panels, a 150mg specimen is suggested. It’s advisable to utilize a jeweler’s scale for accuracy. Should scalp hair be unattainable, the same amount of body hair is suitable. References to head hair indicate scalp hair only, with body hair encompassing other types (like facial or axillary).
Process Overview
The testing procedure encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially integrated into the laboratory system. The process involves checking that the sample is correctly sealed and transported, assigning a Laboratory Accessioning Number (LAN) randomly, and completing any necessary data input absent from the electronic chain of custody.
Screening is a preliminary drug abuse test. While Screening cost-effectively eliminates drug usage in most cases, results indicating usage must undergo confirmation to be valid in legal settings. Any sample presumed positive requires further verification.
For specimens suspected to be positive in Screening, additional hair is extracted from the original sample and readied for Extraction. Here, drugs are retrieved from hair at much reduced concentrations than in other techniques (e.g., urine or saliva), showcasing the complexity of hair drug analysis.
Positive Screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positives undergo a cleaning phase before confirmation, if needed. The complete lab process, from Accessioning to Confirmation, adheres to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditations.
Advantages of hair drug testing:
Limitations:
Note: Although sometimes termed "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.
