Hair Follicle Drug Testing - Fair Hill, MD

What it is, How it works

Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged history of substance intake by capturing biomarkers in its strands as they grow. When obtained near the scalp, it can reveal up to a 3-month timeframe for drug and alcohol detection. Hair collection is easy to execute, somewhat resistant to tampering, and convenient for shipping.

An ideal sample for screening and confirmation consists of a 1.5-inch length of approximately 200 strands (comparable to a #2 pencil), which equates to 100mg of hair. For EtG, additional tests, or over 10-panel assessments, 150mg is advised. Using a jeweler’s scale to measure the specimen is suggested. If scalp hair isn't accessible, a similar volume of body hair can be used. 'Head hair' denotes scalp hair only, whereas 'body hair' includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing for a drug test outcome features four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is processed into the laboratory's system. This ensures the sample is properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and enters any extra data not available via an electronic chain of custody system.

Screening serves as an initial check for substances of abuse. It is a cost-efficient method for detecting drug usage in most samples, but a positive result needs verification to hold in legal settings. Samples with presumptive positives in Screening require further confirmation.

For presumptive positives in Screening, additional hair from the initial sample is prepared for Extraction. During this stage, the drug is isolated from the hair in significantly lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology.

Confirming any screening positives is done via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives are cleaned before confirmation if necessary. The complete lab process, from Accessioning to Confirmation, is reviewed under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Longer detection periods: Hair drug testing identifies drug use over a period of up to 90 days, unlike the shorter detection period of urine tests.
• Hard to manipulate: It is tough to falsify a hair drug test, producing more reliable outcomes.
• Offers historical insight: It shows a drug usage pattern over time, not solely recent use.

Limitations:

• Inability to trace recent usage: Drugs become detectable in hair only after about 5-7 days.
• Expense: Hair drug testing is generally costlier than alternative methods.
• Inconsistent results: Variables like hair color and personal hair growth differences can influence drug metabolite concentrations.

Note: Despite being called "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Fair Hill, MD, hair follicle tests are proving superior to urine tests for various reasons. They offer greater detection accuracy and reliability, giving a more comprehensive understanding of drug use history. In contrast, traditional urine tests are limited to recent detection windows.

Hair follicle testing provides an extensive reporting period, making it the preferred choice for employers with zero-tolerance policies. Unlike urine tests, hair analysis is less susceptible to manipulation, offering a true image of substance use over the months.

Extended Detection Window

The extended detection window of hair follicle testing in Fair Hill, MD is unmatched. Unlike urine tests, which only provide a snapshot of recent substance use, hair tests provide a look back over 90 days, giving employers a deeper insight into an applicant's or employee's past drug use.

This extensive timeframe allows organizations to make more informed decisions, reducing the risk associated with hiring individuals with undisclosed substance abuse issues. The long detection period is valuable for sustained assessment of drug use habits.

Tamper-Resistant Testing Method

Hair follicle tests in Fair Hill, MD are known for being a tamper-resistant method. Unlike urine tests, hair testing significantly reduces the risk of sample adulteration, ensuring results are trustworthy and valid.

This method minimizes the opportunity for manipulation, offering employers and authorities reliable and unquestionable results. The observed collection process further bolsters the integrity of the testing, maintaining test authenticity.
