Hair Follicle Drug Testing - Castine, OH

What it is, How it works

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drug intake by embedding biomarkers within the hair strand's fibers as it grows. When gathered close to the scalp, hair can offer a detection window of up to roughly 3 months for alcohol and other substances. Hair collection is straightforward, somewhat resistant to tampering, and simple to transport.

A sample measuring 1.5 inches consisting of approximately 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp will produce 100mg of hair, the optimal sample for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen weighing 150mg is preferred. We advise using a jeweler’s scale to weigh the specimen. If scalp hair is not present, an equivalent amount of body hair can be collected. 'Head hair' refers exclusively to scalp hair. 'Body hair' encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates the initial processing of a sample into the laboratory’s system. This step includes confirming that the sample was sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.

Screening offers an initial rapid assessment for drugs of abuse. Although Screening is a cost-efficient approach to exclude drug use in most samples, a positive result requires confirmation to be valid in legal contexts. Samples flagged as presumptively positive in Screening must undergo a secondary confirmation.

In cases where a sample is presumptively positive during the Screening phase, additional hair is extracted from the original specimen and set for Extraction. During this phase, substances are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening a challenging method to execute.

Confirmation of any positive Screening findings is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptively positive are washed prior to confirmation if necessary. The comprehensive laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can identify drug usage for up to 90 days, as opposed to urine tests with a shorter detection period.
• Challenging to manipulate: Hair drug tests are difficult to deceive, leading to more reliable results.
• Delivers chronological data: They provide a history of drug usage over time, rather than just capturing recent use.

Limitations:

• Incapable of recent use detection: It generally takes around 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests are usually costlier than alternative drug testing methods.
• Result variability: Variables such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: While commonly termed as "hair follicle tests", the analysis focuses on the hair strand, rather than the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Castine, OH Hair follicle tests boast several advantages over traditional urine tests, making them a preferred choice for accurate substance detection.
