Accredited Drug Testing offers thorough hair follicle drug testing services in Castroville, Texas. Should you require a test for drugs or alcohol, Accredited Drug Testing is proficient in hair analysis, with centers available nationwide to perform the procedure. Typically, 1.5 to 2 inches of hair from the scalp or body is needed. Hair analysis can detect substances, alcohol/ETG, or other specific needs.
In recent times, hair follicle drug testing has become a popular method for detecting drug use. Increasingly, employers, judiciary bodies, and substance abuse experts are opting for hair tests over traditional urine tests. This testing method is favored by organizations with strict no-drug policies, legal systems, and probation supervision. Its key advantage is its extended detection period of up to 90 days, with the collection process strictly monitored, making deception almost impossible. However, for identifying recent drug use within five days, urine testing remains more precise.

The use of hair testing has become recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug intake by incorporating biomarkers within the fibers of the developing hair strand. A sample collected near the scalp can reveal substances up to around a three-month window. Collecting hair is straightforward, relatively tamper-resistant, and convenient for shipping.
A 1.5-inch section containing approximately 200 strands of hair (around the thickness of a #2 pencil) nearest the scalp provides 100mg of hair, which is the ideal amount for both screening and confirmation purposes. For EtG, additional testing, or assessments exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale for weighing the sample is recommended. If hair from the scalp isn't available, an equivalent quantity of body hair can be used. References to head hair are specific to scalp hair only, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary stages in the laboratory handling of a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into the lab’s system, which includes confirming proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry omitted in an electronic chain of custody system.
Screening entails an initial swift examination for drug traces. Although Screening offers a budget-friendly means to exclude drug presence in most samples, a positive outcome requires confirmation to hold up in legal contexts. Samples with a presumptive positive result during Screening necessitate a further confirmation process.
In cases where a sample yields a presumptive positive in the Screening phase, further hair is retrieved from the original sample and readied for Extraction. During this process, drugs are isolated from hair at concentrations much lower than other methods (e.g., urine or oral fluid), attributing to the complexity of performing hair drug screening.
Confirmation of any positive screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. The whole laboratory process, from Accessioning through Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair accreditation and the ISO / IEC 17025 standards.
