Hair Follicle Drug Testing - Horsehead, MD

What it is, How it works

Hair testing has increasingly gained recognition as an effective method for detecting drug and alcohol consumption. Hair captures long-term evidence of alcohol and drug use by embedding biomarkers within the fibers of the hair shaft as it grows. When taken from near the scalp, this method can offer a detection period of up to roughly three months for both alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and convenient for transportation.

A hair sample of about 200 strands (approximately the width of a #2 pencil) cut closest to the scalp provides 100mg, which is the optimal amount for initial testing and confirmation. For EtG, additional requirements, and tests exceeding 10 panels, 150mg of the sample is advised. It is suggested to weigh the sample using a jeweler's scale. If scalp hair cannot be obtained, an equivalent quantity of body hair might be used. References to head hair imply only scalp hair, while body hair encompasses other types (facial, axillary, etc.).

Process Overview

The laboratory process for testing drug presence encompasses four crucial stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the procedure of introducing the sample into the laboratory's framework. It entails verifying proper sealing and shipping of the sample, generating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.

Screening provides a preliminary, rapid assessment for substances of abuse. While it is economically efficient in discounting drug use in most samples, the findings from a positive screen must undergo confirmation to be valid in a legal setting. Samples showing presumptive positives in Screening necessitate confirmatory testing.

Should a sample test presumptively positive during Screening, additional hair is extracted from the original sample for further processing in the Extraction phase. In this stage, drugs are retrieved from hair at significantly lower concentrations than in other testing methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.

Confirmation of any screening positives employs GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Prior to confirmation, all presumptive positive samples are washed as required. The comprehensive laboratory procedure from Accessioning through Confirmation is subject to review under both the CAP (College of American Pathologists) Hair guidelines and accreditation according to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can reveal drug use for as long as 90 days, unlike urine tests which have a briefer detection duration.
• Resistant to tampering: It is particularly challenging to alter a hair drug test, rendering results more reliable.
• Provides usage history: It furnishes an overview of drug use patterns over time, rather than just recent usage.

Limitations:

• Incapable of identifying recent use: Detection of drugs in hair takes about 5-7 days.
• Expense: Hair drug screenings typically cost more than other drug testing methods.
• Result fluctuations: Differences in hair color and individual hair growth characteristics can influence drug metabolite concentrations in hair.

Note: Commonly termed as "hair follicle tests", the analysis is performed on the hair shaft rather than the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

In Horsehead, MD, hair follicle testing is often superior to urine testing due to its improved detection accuracy and reliability. Unlike urine tests, which only detect recent drug use, hair tests offer a broader detection window, providing a more extensive view of an individual's drug history for employers and adjudicators.

The advantages of hair analysis over urine lie in its ability to capture long-term substance exposure. This method is favored for its heightened detection precision, giving Horsehead, MD employers and regulators an edge in evaluating substance use.

Extended Detection Window

Hair follicle tests in Horsehead, MD extend drug use detection up to 90 days, providing deeper insights into one's substance history. This lengthy detection span differentiates it from other testing methods, allowing employers an extended assessment window.

The extended detection window of hair follicle tests enables comprehensive evaluations of an individual's past substance use, up to three months. This broad timeframe is vital for Horsehead, MD employers seeking to understand applicant or employee habits thoroughly.

Tamper-Resistant Testing Method

The tamper-resistant nature of hair follicle tests significantly reduces the risk of sample alteration in Horsehead, MD. This method ensures the integrity and authenticity of results, a necessary asset for legal and professional evaluations.

Sample integrity with hair follicle tests comes from the difficulty of adulterating hair samples. In Horsehead, MD, employers and legal bodies can trust these tamper-resilient methods to yield undoubted results, minimizing manipulation risks.
