Hair Follicle Drug Testing - Clayton, MO

What it is, How it works

Hair assessment is now recognized as a robust method for identifying drug and alcohol consumption. Hair preserves a long-term sequence of alcohol and drug use by embedding biomarkers within the fibers of the hair as it grows. When sampled near the scalp, hair can show a detection timeline of up to roughly three months for alcohol and drugs. It's easy to gather, tough to falsify, and simple to transport.

A sample measuring 1.5 inches of around 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp yields 100mg, the optimal amount for testing and verifying. For EtG extensions and examinations beyond 10 panels, 150mg is suggested. We suggest measuring the sample with a jeweler’s scale. In cases where scalp hair isn't available, an equivalent quantity of body hair can be used. When mentioning head hair, this refers only to scalp hair, while body hair denotes all other types (such as facial, axillary, etc.).

Process Overview

The primary four steps in the laboratory evaluation of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is about initially entering a sample into a lab's system. It involves checking that the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any other data needed that's absent from an electronic chain of custody system.

Screening is an initial rapid assessment for drugs of abuse. While Screening is cost-efficient for eliminating drug use in most cases, any positive screening must be confirmed to be valid in legal settings. Samples that test presumptively positive during Screening will require an additional verification.

If a sample notes presumptive positivity at the Screening phase, more hair is taken from the original sample for Extraction. In Extraction, drugs are isolated from hair at significantly lower concentrations compared to other methods (like urine or oral fluid), which is why hair drug testing is the most challenging method to perform.

Validating any presumptive positive screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positivity receive a wash before confirmation as required. The complete laboratory process from Accessioning to Confirmation undergoes review following the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Prolonged detection timeline: Hair drug tests have the ability to identify drug use for as long as 90 days, unlike urine tests which have a shorter detection span.
• Hard to tamper with: Hair drug tests are difficult to deceive, enhancing result accuracy.
• Offers historical insights: It reveals a pattern of drug usage over time, not just recent activities.

Limitations:

• Incapable of detecting recent use: Drugs need roughly 5-7 days to become traceable in hair.
• Expense: Hair drug tests are typically costlier than alternate drug testing modes.
• Result variability: Elements like hair color and individual variances in hair growth can influence drug metabolite concentration in the hair.

Note: Although often labeled as "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Clayton, MO, hair follicle tests provide significant advantages over traditional urine tests. Hair testing not only identifies drug use more accurately but also proves more reliable in preventing user interference or cheating the test. This results in a more truthful reflection of an individual's substance use history.

One key benefit is the extended detection window that hair tests provide, allowing for identification of drug use over a 90-day span, unlike urine tests which typically only capture recent consumption. Thus, hair testing offers a broader view of an individual’s substance usage patterns.
