Hair Follicle Drug Testing - Lindenwood, IL

What it is, How it works

Hair testing has gained a reputation as a highly effective method for identifying drug and alcohol consumption. Hair offers an extended timeline of alcohol and drug use by holding biomarkers within the strands of growing hair. When secured from the scalp area, hair can indicate up to a 3-month period of drug and alcohol usage. The collection process is straightforward, tampering is challenging, and shipping is uncomplicated.

A hair sample measuring 1.5 inches, approximately 200 strands (equivalent to a #2 pencil's width), closest to the scalp yields 100mg, which is optimal for screening and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg sample is preferable. We advise employing a jeweler's scale for weighing the sample. If scalp hair isn't available, a similar amount of body hair might be taken. By head hair, we mean scalp hair exclusively, while body hair includes all other types (facial, axillary, etc.).

Process Overview

The primary stages in laboratory processing a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample within a laboratory system. This process verifies the sample's seal and shipping integrity, allocates a random LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry absent in an electronic chain of custody framework.

Screening is a preliminary rapid assessment for drugs of abuse. Screening is an economical means to discount drug use in most samples, yet a positive screen necessitates confirmation for legal admissibility. Samples that preliminarily test positive in Screening require further Confirmation.

If Screening results are presumptively positive, additional hair from the initial sample is used for Extraction. Drugs are extracted from hair in much lower concentrations compared to other techniques (e.g., urine or oral fluid), marking hair drug screening as the most challenging methodology.

Confirmation of positive screening outcomes uses GC/MS, GC/MS/MS, or LC/MS/MS. Positive samples undergo washing prior to Confirmation as required. The entire testing process from Accessioning to Confirmation undergoes review per CAP (College of American Pathologists) Hair standards and compliance with ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests reveal drug use for up to 90 days, unlike urine tests which have a shorter detection duration.
• Difficulty to cheat: Cheating a hair drug test is extremely tough, enhancing the accuracy of results.
• Provides historical data: These tests can illustrate a drug use pattern over time, unlike just recent usage.

Limitations:

• Cannot detect recent use: It takes about 5-7 days post-consumption for drugs to surface in hair.
• Cost: Hair drug tests often come with higher costs compared to other testing methods.
• Variations in results: Factors like hair color and personal hair growth variations can impact drug metabolite concentrations in hair.

Note: While commonly called "hair follicle tests", they actually analyze the hair strand, not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

In Lindenwood, IL, hair follicle testing stands out over traditional urine tests in several ways. Hair analysis offers superior detection periods, reaching as far back as 90 days, compared to the short window available with urine tests. Additionally, hair samples provide a more reliable reflection of an individual's substance use patterns due to their resilience against tampering and the sheer length of historical detection they afford.

Extended Detection Window

One of the most significant advantages of hair follicle testing in Lindenwood, IL is its extended detection window. Unlike other methods that may only capture recent usage, hair testing can reveal drug activity up to 90 days prior. This means employers seeking to establish a comprehensive picture of an individual’s substance involvement can rely on hair testing to obtain this essential historical perspective.

Tamper-Resistant Testing Method

The effectiveness of hair follicle drug testing is enhanced by its tamper-resistant nature, as observed in Lindenwood, IL.
