Accredited Drug Testing offers thorough hair follicle drug testing services in Princeton, Texas. Should you require a hair drug or alcohol test, we specialize in hair testing and maintain testing centers across all cities nationwide capable of conducting such tests. Typically, 1.5 to 2 inches of hair from the head's crown or body is required. Hair tests can be tailored for drugs, alcohol/ETG, or other specific options.
In recent times, hair follicle drug testing has increasingly become a favored method for drug screening. Numerous employers, legal authorities, and Substance Abuse experts are opting for hair drug tests over conventional urine tests. Hair follicle drug tests serve employers with strict no-drug policies, legal entities, and probationers with a significant advantage being a longer detection window for drug use, generally up to 90 days, with the added benefit of observed collection making it hard to manipulate results. However, for detecting drug use within the past 5 days, the urine test remains the most precise method.
* You must register by phone or online to receive your donor pass/registration prior to proceeding to the testing center. You must bring a valid government issued ID along with the registration/barcode number which was sent to you by email.

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair gives an extended timeline of substance use by embedding biomarkers within the strands as they grow. When obtained near the scalp, it can reflect a drug or alcohol detection span of up to three months. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.
A sample measuring 1.5 inches and comprising around 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg, which is optimal for both screening and confirmation tests. For EtG, additional tests, and tests beyond 10 panels, 150mg is advisable. We suggest using a jeweler's scale for weighing the sample. In cases where scalp hair is inaccessible, a similar amount of body hair can be used. "Head hair" signifies scalp hair exclusively, while "body hair" includes all other hair types (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where the sample is integrated into the lab’s system, which includes verifying the proper sealing and shipping of the sample, allocating a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an electronic chain of custody.
Screening is a preliminary assessment for drug presence. While efficient in eliminating drug use suspicions from most samples, a positive screen must be confirmed for legal acceptance. Presumptive positives in Screening require a follow-up confirmation.
For presumptive positives found during Screening, additional hair is extracted from the original sample for the Extraction phase. This phase involves retrieving drugs from hair at a lower concentration than other methods (e.g., urine or oral fluid), which makes hair drug screening a challenging process.
Confirmation of any positive screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples marked as presumptive positives undergo a washing process before confirmation, as necessary. The entire laboratory process from Accessioning to Confirmation undergoes review according to both CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards.
