At Accredited Drug Testing, we offer comprehensive hair follicle drug testing services in San Carlos Number 1 Colonia, Texas. If a hair drug or alcohol test is needed, we are experts in this type of testing and have centers nationwide ready to perform them. Typically, 1.5 to 2 inches of hair from the crown or body is sufficient. These tests can detect drugs, alcohol/ETG, or can be tailored for specific needs.
In recent years, hair follicle drug testing has become more prevalent. Employers, courts, and Substance Abuse professionals often favor this over standard urine tests. It's preferred by those with strict no-drug policies as it offers a detection period of up to 90 days, using an observed collection, making tampering nearly impossible. However, for recent drug use detection within the last 5 days, urine tests remain the most reliable.
* 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 testing is regarded as an effective method for identifying drug and alcohol consumption. Hair offers an extended timeline of substance use by capturing biomarkers in the growing hair strand. When sampling hair close to the scalp, it can identify alcohol and drugs up to a roughly 3-month period. Hair is easy to gather, relatively challenging to tamper with, and simple to send.
A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil's thickness) nearest to the scalp will yield 100mg, the optimal sample for screening and validation. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the specimen is suggested. We advise utilizing a jeweler’s scale for specimen weighing. If scalp hair isn't available, an equivalent amount of body hair can be used. When discussing head hair, we specifically mean scalp hair. Body hair pertains to all other hair categories (facial, axillary, etc.).
Process Overview
The four primary stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary integration of a sample into a lab’s system. This entails checking if the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and filling in any further data entry absent from an electronic chain of custody system.
Screening consists of a preliminary rapid check for drug usage. Although Screening is a cost-efficient method to exclude drug use in most samples, a positive screen must be corroborated to be valid in court. All samples testing presumptively positive in Screening necessitate secondary confirmation.
If a sample tests presumptively positive during the Screening process, additional hair is extracted from the initial specimen and made ready for Extraction. During this phase, drugs are drawn from hair at a far lower concentration than other techniques (e.g., urine or oral fluid), which is why hair drug screening is the most complex procedure to execute.
Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The entire lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
