Hair Follicle Drug Testing - Anatone, WA

What it is, How it works

Hair analysis is recognized as an effective instrument for identifying drug and alcohol consumption. Hair offers a long-term record of drug and alcohol use by embedding biomarkers within the fibers of the hair as it grows. When obtained near the scalp, hair can offer a detection period of up to roughly three months for substances. Collecting hair is straightforward, relatively tamper-resistant, and easy to transport.

A sample measuring 1.5 inches from approximately 200 hair strands (comparable to a #2 pencil's diameter) nearest to the scalp yields 100mg of hair, the ideal amount for both screening and verification. For EtG, additional tests, or tests that exceed 10 panels, 150mg of the sample is advisable. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair can't be obtained, a similar amount of body hair can be used. When talking about head hair, it refers solely to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

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

Accessioning deals with the initial integration of a sample into the lab's system. Tasks include confirming the sample's seal and proper shipment, assigning it a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody system.

Screening is a preliminary assessment for substance abuse. Though Screening is a cost-effective method for ruling out drug use in most samples, any positive screen must undergo confirmation to be court-admissible. Presumptively positive samples in Screening necessitate further confirmation.

If a sample tests presumptively positive during Screening, additional hair is extracted from the initial sample for the Extraction process. This phase involves extracting drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug testing is the most challenging method to execute.

Confirmation of positive screening outcomes is executed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are washed before confirmation when necessary. The comprehensive lab procedure, from Accessioning to Confirmation, is examined under the CAP (College of American Pathologists) Hair category and accords accreditation with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection period: Hair drug screening can trace drug consumption for up to 90 days, in contrast to the shorter detection span of urine tests.
• Difficult to manipulate: Hair drug screening is very challenging to deceive, enhancing the reliability of results.
• Provides usage history: Offers an overview of drug use trends over time rather than only recent consumption.

Limitations:

• Inability to detect recent usage: It requires about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests usually cost more than other drug testing techniques.
• Result variability: Factors such as hair color and differences in individual hair growth can impact how drug metabolites concentrate in hair.

Note: Although commonly called "hair follicle tests", the analysis is performed on the hair strand itself, not the follicle beneath the scalp.
