Hair testing is recognized as an effective means for detecting drug and alcohol consumption. It captures a prolonged history of substance use by embedding biomarkers within the strands of growing hair. With samples taken near the scalp, hair testing can detect alcohol and drugs for as long as a 3-month timespan. It's straightforward to gather, challenging to tamper with, and convenient to transport.
A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil in size) from the scalp yields 100mg, which is the optimal sample size for analysis. For EtG, additional tests, or those exceeding 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair isn’t accessible, a similar quantity of body hair is acceptable. "Head hair" refers specifically to scalp hair, while "body hair" encompasses all other types (e.g., facial, axillary).
Process Overview
The laboratory processing for a drug test comprises four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of cataloging a sample into a lab’s system. It entails checking that the sample was sealed and shipped correctly, issuing a random LAN (Laboratory Accessioning Number), and completing any missing data not available via an electronic chain of custody system.
Screening consists of a preliminary rapid assessment for drugs. Although a cost-efficient method to eliminate drug usage in most cases, a positive outcome in this phase requires confirmation to be valid in legal proceedings. Presumptive positives from Screening demand further confirmation.
Should a sample test presumptively positive during Screening, more hair is extracted from the initial collection and prepped for Extraction. This phase draws drugs out of the hair at considerably lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing a complex methodology to execute.
Confirmation of any positive screening findings is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples presumed positive undergo a wash before confirmation if necessary. The entire process, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:

Note: While termed "hair follicle tests", the test analyzes the hair strand rather than the follicle beneath the scalp.
The preference for hair follicle testing in Mart, TX, highlights its advantages over traditional urine tests. Hair testing offers a longer detection period, making it much harder to bypass and providing a more comprehensive insight into substance use. While urine tests might miss long-term drug consumption, hair tests detect substances used over months, proving their superior accuracy and reliability for varied testing needs.
Hair follicle testing in Mart, TX, is noteworthy for its extended detection window of up to 90 days. This lengthy period allows employers to gauge an individual’s substance use history well beyond the limited few days detectable via urine tests. Thus, hair testing offers a valuable method for understanding long-term drug use and informing employment or regulatory decisions effectively.
Hair follicle testing in Mart, TX, is renowned for its tamper-resistant methodology. This method significantly lowers the chances of adulteration, ensuring that the collected samples yield unwavering and verifiable results. By reducing manipulation risks, hair testing stands as a robust option for accurate and authentic substance use detection, reinforcing trust in the test outcomes.
