Hair Follicle Drug Testing - Longview, WA

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and drug intake by encapsulating biomarkers within the strands as the hair grows. When taken near the scalp, hair provides roughly a 3-month window for detecting alcohol and drugs. Hair collection is straightforward, fairly resistant to tampering, and can be easily shipped.

A 1.5-inch section consisting of around 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the ideal sample amount for screening and confirmation. For EtG, additional tests, or tests beyond 10 panels, 150mg of the sample is recommended. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair cannot be obtained, an equivalent quantity of body hair can be used. When we mention head hair, we mean scalp hair only. Body hair includes all other forms such as facial or axillary hair.

Process Overview

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

Accessioning refers to the initial integration of a sample into the lab's system. This involves verifying that the sample was appropriately sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and filling in any additional data entry not covered by an electronic chain of custody.

Screening conducts an initial rapid assessment for drug abuse. While Screening provides a cost-efficient means of excluding drug use for most samples, a positive screening result requires confirmation for court admissibility. Any samples that test presumptively positive during Screening necessitate a secondary confirmation.

If a screening suggests a positive result, further hair is extracted from the original specimen and readied for Extraction. This step involves extracting drugs from hair at concentrations lower than in other methods (such as urine or oral fluid), highlighting the challenges of hair drug screening.

Confirmation of positive screening outcomes employs GC/MS, GC/MS/MS or LC/MS/MS techniques. All presumptively positive samples undergo necessary washing before confirmation. The entire lab process from Accessioning to Confirmation is conducted under the oversight of the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection period: Hair drug tests can identify drug use up to 90 days, in contrast with urine tests' shorter detection time.
• Hard to manipulate: Hair drug tests are challenging to deceive, ensuring more reliable results.
• Offers historical insights: They provide a drug use timeline over an extended duration, not just recent usage.

Limitations:

• Not effective for recent detection: About 5-7 days are required for drugs to become detectable in hair.
• Costly: Hair drug tests generally incur higher costs compared to other methods.
• Result variability: Factors such as hair color and individual hair growth differences can impact drug metabolite concentrations in hair.

Note: Although typically termed "hair follicle tests", the analysis targets the hair strand rather than the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle tests reign superior to urine tests in Longview, WA due to their enhanced detection accuracy and reliability. Unlike urine tests, they offer a comprehensive view of drug use patterns, reducing false negatives and enhancing safety.
