Hair testing has emerged as an effective means for detecting drug and alcohol consumption. Hair captures a prolonged record of drug and alcohol use by embedding biomarkers within its strands. When collected near the scalp, hair offers an approximate 3-month detection timeframe for alcohol and drugs. This method is straightforward to gather, challenging to tamper with, and simple to transport.
A 1.5-inch section of roughly 200 hair strands (comparable to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the perfect amount for both initial tests and confirmatory analysis. For EtG, additional assessments, or tests exceeding 10 panels, 150mg is advisable. It is best to weigh the sample using a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair may be used. The term "head hair" specifically denotes hair from the scalp. Alternatively, "body hair" encompasses all other varieties of hair (facial, axillary, etc.).
Process Overview
There are four primary stages in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial processing of a sample within a laboratory's system. This step involves ensuring that the sample was correctly sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and filling in any extra data not provided by an electronic chain of custody system.
Screening comprises an initial rapid review for substances of abuse. While this is a cost-efficient method for excluding drug use in most samples, any positive findings must be confirmed for the result to be court-admissible. Samples that test presumptively positive require additional confirmation.
Should a sample test presumptively positive during Screening, additional hair is taken from the original specimen for Extraction. This phase involves drug extraction from hair, which occurs at significantly lower concentrations than with other methodologies (e.g., urine or oral fluid). Thus, hair drug screening is the most complex methodology to execute.
Confirmation of any positive screening result is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples require washing before confirmation as necessary. The entire procedure, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and accredited according to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly referred to as "hair follicle tests", the actual test examines the hair strand and not the follicle itself beneath the scalp.
When comparing hair follicle testing to traditional urine tests in Ophir, AK, the former becomes a superior option for its advanced detection abilities. Unlike urine tests, hair analysis provides a more comprehensive overview, extending beyond recent consumption. Hair testing minimizes evasion techniques, demonstrating more consistent reliability and accuracy in substance detection.
Hair follicle testing offers an extended detection window in Ophir, AK, which is one of its significant advantages. Capable of tracking drug use over a span of up to 90 days, this method surpasses others. This prolonged detection period aids employers by supplying a thorough insight into a test subject's substance usage history, critical for making informed decisions.
In Ophir, AK, the tamper-resistant nature of hair follicle testing greatly reduces the likelihood of sample tampering or adulteration. With hair samples being immensely more challenging to alter compared to other testing methods, results are more reliable and indisputable. This resistance to tampering supports the integrity of the testing process.
