Hair Follicle Drug Testing - Limestone, OK

What it is, How it works

Hair analysis is recognized as a robust method for identifying drug and alcohol consumption. It offers an extensive timeline for substance use by capturing biomarkers within the hair's growing fibers. Samples gathered near the scalp can reveal drug and alcohol traces for up to about 90 days. The collection process is straightforward, tampering is relatively challenging, and transportation is hassle-free.

A sample size of 1.5 inches, consisting of roughly 200 hair strands (approximately the diameter of a #2 pencil) near the scalp offers 100mg, which is optimal for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen weight of 150mg is suggested. Utilizing a jeweler’s scale for measuring the specimen is advised. If scalp hair is absent, a similar quantity of body hair can be used. The term "head hair" refers specifically to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

The comprehensive steps in laboratory drug testing are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails incorporating a sample into the lab's system. This procedure involves ensuring the sample remains sealed and is shipped correctly, assigning a random Laboratory Accessioning Number (LAN), and filling in any additional data not included in the electronic chain of custody.

Screening acts as a preliminary examination for abused substances. Although Screening is a cost-efficient approach to exclude drug use in most samples, a positive result demands confirmation to be legally viable. Those samples with presumptive positive results require subsequent confirmation.

Presumptively positive samples necessitate more hair from the original sample for Preparation for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), which makes hair drug screening exceptionally challenging.

Verification of positive screening outcomes is conducted using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Any samples with false positives are washed pre-confirmation if required. The entire lab procedure from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditations.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for up to 90 days, as opposed to urine tests with shorter detection periods.
• High fraud-resistance: Cheating a hair drug test is exceedingly challenging, resulting in highly accurate findings.
• Provides usage trends: It reveals a pattern of drug consumption over time, not just recent use.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Typically, hair drug tests incur higher costs compared to other methods.
• Variability in results: Influences like hair color and personal variations in hair growth can impact drug metabolite concentrations in hair.

Note: Commonly called "hair follicle tests," the examination focuses on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Limestone, OK, hair follicle testing offers numerous advantages over traditional urine tests. Its superior detection accuracy stems from its ability to reveal substance use over an extended period, which urine tests fail to achieve.
