The examination of hair has emerged as a significant instrument for identifying drug and alcohol consumption. Hair captures biomarkers in the strands' fibers over time, offering a comprehensive history of substance use. When taken close to the scalp, hair can show substance exposure for up to about three months. It's straightforward to gather, hard to tamper with, and convenient to send.
A hair specimen, measuring 1.5 inches and consisting of roughly 200 strands (similar to a #2 pencil in thickness) near the scalp, supplies 100mg of hair, an optimal quantity for analysis and verification. For EtG, additional tests, or tests beyond 10 panels, 150mg of the sample is suggested. We suggest measuring the sample using a jeweler's scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be used. When mentioning head hair, we mean only scalp hair. Other hair types (facial, axillary, etc.) are referred to as body hair.
Process Overview
There are four primary stages in processing a drug test result in the lab: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample enters the lab's system. This process includes checking that the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry not available from an electronic chain of custody system.
Screening performs a preliminary rapid check for the presence of drugs. While it's an economical method to eliminate drug use in most samples, a positive result from screening must be confirmed for court acceptance. Samples that give presumptive positive results in screening require a further confirmation.
If a sample shows a presumptive positive result during Screening, additional hair is extracted from the original sample and readied for Extraction. In Extraction, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing the most challenging methodology.
Confirmation of a positive screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation as necessary. The complete lab process, from Accessioning to Confirmation, adheres to both the CAP's Hair designation (College of American Pathologists) and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Often labeled as "hair follicle tests", they actually analyze the hair strand, not the follicle beneath the scalp.
In Navarro, TX, the benefits of hair follicle testing clearly surpass those of traditional urine tests. Hair tests offer superior detection accuracy and reliability, mainly due to their longer detection period, which can reveal drug use history up to 90 days, unlike urine tests that have a shorter detection window.
While urine tests remain popular for immediate screening, hair follicle tests are becoming increasingly favored thanks to their unparalleled ability to uncover substance abuse over extended periods. This capability not only provides better overall insights but also enhances confidence in the results obtained from hair testing.
The advantage of hair follicle testing in Navarro, TX, lies significantly in its extended detection window. Capable of detecting drug use for up to 90 days, this method gives employers a thorough understanding of an individual's substance history, surpassing the brief detection span of urine tests.
