Hair Follicle Drug Testing - Petersburg, MI

What it is, How it works

Hair testing is increasingly being recognized as an effective method for identifying use of drugs and alcohol. By capturing biomarkers within the fibers of a growing hair strand, hair reveals a prolonged record of alcohol and drug presence. When collected near the scalp, hair delivers a detection range of up to roughly 90 days for alcohol and other drugs. It is straightforward to collect, not easily tampered with, and convenient to transport.

A 1.5-inch segment consisting of approximately 200 hair strands (comparable to a #2 pencil in thickness) near the scalp will yield 100mg of hair, which is an ideal sample size for analysis and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a specimen weighing 150mg is advised. Using a jeweler’s scale to measure the specimen is recommended. In the absence of scalp hair, an equivalent quantity of body hair can be used. It should be noted that head hair specifically refers to scalp hair. All other types of hair (such as facial, axillary) are considered body hair.

Process Overview

There are four principal phases in processing a drug test in the laboratory: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves initiating a sample into a lab's system. The process ensures the sample was adequately sealed and transported, allocates a unique LAN (Laboratory Accessioning Number), and finalizes any extra data tasks not completed by an electronic chain of custody method.

Screening provides an initial assessment for drugs of abuse and acts as a cost-efficient method to determine drug absence in numerous samples. However, a positive screening result requires verification for legal acceptability. Samples identified as positive during Screening necessitate an additional confirmation step.

Should a sample be marked presumptively positive during Screening, extra hair is collected from the original sample for the Extraction process. This phase involves removing drugs from the hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), contributing to the inherent complexity of hair drug assessments.

The final Confirmation for any positive screening outcome uses GC/MS, GC/MS/MS, or LC/MS/MS methods. Positive samples undergo washing prior to Confirmation as required. The full laboratory workflow, from Accessioning through Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair tests can identify drug use for as long as 90 days, unlike urine tests which have a more abbreviated detection period.
• Challenging to cheat: Cheating a hair drug test is considerably hard, leading to more precise outcomes.
• Provides a timeline of data: It can trace a pattern of drug consumption over a time span, rather than just recent use.

Limitations:

• Cannot identify recent use: Drugs take approximately 5-7 days post-use to appear in hair.
• Expense: Hair tests are typically more costly than other drug testing methods.
• Result variations: Elements like hair color and personal differences in hair growth can influence drug metabolite concentration within hair.

Note: Often called "hair follicle tests", it is the hair strand being analyzed, not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

In Petersburg, MI, hair follicle testing offers exceptional advantages over traditional urine tests. One primary benefit lies in its extended detection window, up to 90 days, capturing a wide range of substances. This enables a comprehensive view of the individual's substance habits, which is far superior to the limited time scope of urine tests.

Hair testing is not only more accurate but also more resilient to tampering. Unlike urine tests, it's almost impossible to manipulate hair samples. Hence, hair follicle testing guarantees the reliability that employers and officials in Petersburg seek, enhancing their assurance in test results.

Extended Detection Window

One of the outstanding features of hair follicle testing in Petersburg, MI, is its extended detection window of up to 90 days. This extended period greatly benefits employers who need a comprehensive overview of an individual's drug usage history. It provides a clear insight into past behaviors and potential future risks.

The ability of hair tests to track drug use over a substantial period offers better coverage than other test methods. This extended window means that short-term abstinence before testing won't mask past usage, ensuring that those responsible for making decisions have the full picture.

Tamper-Resistant Testing Method

In Petersburg, MI, hair follicle testing presents a tamper-resistant method that notably reduces the possibility of sample adulteration. Since the sample can't be altered easily, the results remain trustworthy and can be relied upon for accurate decision-making.

The integrity of hair test results stems from an observed collection process, ensuring that samples are secured properly. This integrity ensures results remain unquestionable, providing peace of mind to employers and organizations who need definitive answers on substance use.
