Hair Follicle Drug Testing - Watertown, WI

What it is, How it works

Hair analysis has gained recognition as an effective means for identifying drug and alcohol consumption. Hair serves as a chronicler of substance use by embedding biomarkers within the strands' fibers as they grow. When sampled near the scalp, hair offers a detection range for alcohol and drugs extending up to roughly 90 days. It's straightforward to collect, relatively hard to tamper with, and convenient to send.

A 1.5-inch section consisting of about 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp yields approximately 100mg of hair, which is the optimal amount for both screening and confirmation. For tests involving EtG, additional analyses, or panels beyond 10, a sample of 150mg is advised. We suggest using a jeweler's scale for weighing the sample. In the absence of scalp hair, an equivalent quantity of body hair may be used. When we mention head hair, we specifically mean scalp hair. Body hair pertains to all other types (like facial and axillary).

Process Overview

The key steps in processing a drug test outcome in the lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a sample into the lab's system. This process involves confirming the sample's proper sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and performing any extra data entry omitted by an electronic chain of custody system.

Screening offers a preliminary rapid assessment for drug misuse. Although it is a budget-friendly strategy to rule out drug use in most samples, a positive screening result necessitates confirmation to be valid in legal settings. All samples showing presumptive positivity in Screening must undergo secondary verification.

If Screening suggests a sample is positive, additional hair is retrieved from the initial sample and readied for Extraction. During this phase, drugs are drawn from hair at significantly lower concentrations than in other methods (such as urine or oral fluid), making hair drug screening the most challenging method to conduct.

Verification of any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity are cleansed before confirmation if required. The comprehensive laboratory sequence from Accessioning to Confirmation undergoes evaluation under the CAP (College of American Pathologists) Hair category and the adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for a stretch of up to 3 months, unlike urine tests which cover a shorter duration.
• Hard to manipulate: Cheating a hair drug test is extremely challenging, enhancing the accuracy of results.
• Yields historical insight: It can depict a trend of drug usage over time, not just recent consumption.

Limitations:

• Cannot identify recent consumption: Drugs become detectable in hair roughly 5-7 days post-use.
• Expense: Hair drug tests often incur higher costs than alternative testing approaches.
• Result variability: Elements like hair pigment and individual differences in hair growth can impact drug metabolite concentration in hair.

Note: While frequently termed "hair follicle tests", the assessment targets the hair strand and not the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

When compared to urine tests, hair follicle testing offers unparalleled benefits in Watertown, WI. This method fails in detecting sporadic usage that occurred months ago, where hair testing excels. Hair tests guarantee superior accuracy, reducing false negatives significantly.
They reflect a more comprehensive history, avoiding the masking pitfalls inherent to urine samples. Thus, for reliability and precision, hair tests are becoming the go-to option for many.

Unlike urine tests that need to be conducted within short detection windows, hair testing allows for longer evaluation timelines. Employers can thus trust results that give a holistic view of an individual’s substance use, over time, without worry of cheating or tampering, common with urine tests.

Extended Detection Window

Hair follicle testing in Watertown, WI, provides insight into a person’s substance use over as long as 90 days. This extended window outmatches traditional testing methods, offering employers a broader understanding of an individual's habits over time.

Thus, hair tests serve as a valuable tool for human resources to assess potential or current employees. It gives them a clear and comprehensive picture, beyond just recent or isolated incidents, enabling informed decision-making in hiring or retention.
