Accredited Drug Testing provides comprehensive hair follicle drug testing services in Bristol, Texas. For those requiring a test for drugs or alcohol, our specialization in hair testing is unmatched, with testing centers available across all cities nationwide. Generally, hair of 1.5 to 2 inches in length from the head or body can be utilized. Hair tests are thorough, analyzing for drugs, alcohol/ETG, or other tailored options.
In recent years, hair follicle drug testing has increasingly become the preferred method for substance screening. Many employers, courts, and substance abuse professionals favor it over traditional urine tests due to its stringent zero-tolerance policy enforcement, used by entities requiring more reliable detection. The key advantage of hair follicle testing is its ability to reflect drug use over a 90-day span, making it nearly impossible to alter. Yet, for detecting recent (within 5 days) drug use, urine tests prove more accurate.

Hair testing is recognized as an effective tool for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of the growing hair strand, hair offers a long-term record of alcohol and drug use. When acquired near the scalp, hair can indicate drug and alcohol usage for about three months. Collection is simple, modification is somewhat challenging, and shipment is straightforward.
A 1.5-inch segment of approximately 200 hairs (roughly the size of a #2 pencil) close to the scalp provides 100mg of hair, which is ideal for screening and confirmation. For EtG, add-ons, and/or tests above 10 panels, it is advised to secure 150mg of the specimen. Using a jeweler’s scale for weighing is recommended. If scalp hair is unavailable, a similar quantity of body hair may be collected. "Head hair" refers exclusively to scalp hair, whereas "body hair" includes all other hair types (facial, axillary, etc.).
Process Overview
The primary stages in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the sample’s initial processing into a laboratory’s system, such as ensuring the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry not covered by an electronic chain of custody system.
Screening is an initial rapid test for drugs of abuse. While it's a cost-effective strategy to rule out drug consumption on most samples, a positive screen must be confirmed to be accepted in court. Any samples showing presumptive positivity in Screening require a secondary confirmation.
If a sample is deemed presumptively positive in Screening, additional hair is taken from the initial specimen for Extraction. In this stage, drug extraction from hair occurs at a lower concentration compared to methods like urine or oral fluid analysis, making hair drug screening the most challenging method to perform.
Confirmation of any positive screening result is achieved via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are washed prior to confirmation as necessary. The whole process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
