The utilization of hair testing has increasingly been acknowledged as an influential method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of a growing hair strand, hair offers an extended historical record of alcohol and drug use. When taken near the scalp, the hair can reveal a detection window for alcohol and drugs extending up to nearly 3 months. Hair collection is straightforward, relatively tamper-resistant, and convenient to transport.
A hair sample measuring 1.5 inches, consisting of about 200 strands (approximating the size of a #2 pencil) closest to the scalp, provides 100mg of hair, which is ideal for screening and confirmation purposes. For EtG, additional analyses, and/or tests exceeding 10 panels, a sample of 150mg is advisable. It is suggested to weigh the sample using a jeweler's scale. If scalp hair cannot be obtained, a similar quantity of body hair can be collected. When mentioning head hair, it specifically refers to scalp hair, while body hair encompasses all other types (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing into the laboratory’s system. This process includes ensuring the sample was properly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and completing any further data entry needed beyond the electronic chain of custody system.
Screening is a preliminary and efficient method to identify drug abuse. While it serves as a cost-effective approach for ruling out drug use in most samples, positive results from Screening require confirmation to be valid for legal proceedings. Samples showing presumptive positivity in Screening need a follow-up confirmation.
For samples with presumptive positivity in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. This phase involves extracting drugs from hair at considerably lower concentrations than in other methods such as urine or oral fluid, making hair drug screening a particularly challenging method to perform.
Confirmation of any positive result in screening is executed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo necessary washing prior to confirmation. The entire laboratory process from Accessioning to Confirmation is examined under the guidelines of the CAP (College of American Pathologists) Hair designation and the accreditation according to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although frequently called "hair follicle tests", this test analyzes the hair strand itself, not the follicle beneath the scalp.
While both hair follicle and urine tests are valid methods of drug detection, hair follicle testing proves more reliable in Clements, KS. Its detection capabilities extend far beyond what urine tests can typically identify.
One significant advantage of hair follicle testing is its extended detection window in Clements, KS. While urine tests generally provide a glimpse into recent usage, hair testing offers a detailed view up to 90 days of drug activity. This lengthier timeline ensures employers and legal systems gain a deeper understanding
Hair follicle drug testing remarkably reduces tampering risks in Clements, KS. The testing method itself is designed to minimize potential adulteration. Advantages of this approach include:
