Hair Follicle Drug Testing - Laurel Hill, LA

What it is, How it works

Hair testing is recognized as an effective instrument for uncovering drug and alcohol consumption. Hair retains an extended history of alcohol and drugs by embedding biomarkers into the fibers of the hair strand as it grows. When the hair collected is near the scalp, it can present up to a roughly 3-month detection timeframe for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and convenient to transport.

A 1.5-inch segment of about 200 hair strands, equating to the size of a #2 pencil and nearest to the scalp, furnishes 100mg of hair, which is the ideal amount for both screening and confirmation purposes. For EtG, add-ons, and/or analyses extending beyond 10 panels, a 150mg specimen is advised. Measuring the specimen on a jeweler's scale is recommended. If scalp hair is not available, an equivalent amount of body hair can be utilized. When referencing head hair, it specifically means scalp hair. Body hair refers to any other hair, such as facial or axillary.

Process Overview

The four primary phases in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is incorporated into a lab's system. This step involves ensuring the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.

Screening entails an initial swift check for substances of abuse. Although Screening is a cost-efficient method to exclude drug use in most samples, a positive screen must be corroborated to be valid in legal contexts. Any samples that show a presumptive positive in Screening require follow-up confirmation.

In cases where a sample is presumptively positive at the Screening phase, more hair is extracted from the initial sample for the Extraction process. At this stage, drugs are extracted from hair at concentrations significantly lower than other methods (such as urine or oral fluid), which is why hair drug screening is the most challenging method to execute.

GC/MS, GC/MS/MS, or LC/MS/MS are used for Confirmation of any positive screening results. All presumptive positive samples undergo washing before confirmation as needed. The complete lab process—from Accessioning to Confirmation—is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, in contrast to urine tests with shorter detection periods.
• Low chance of manipulation: It is highly difficult to deceive a hair drug test, enhancing result accuracy.
• Offers past data: It provides a timeline of drug consumption over a period, not solely recent usage.

Limitations:

• Inability to identify recent consumption: Drugs take about 5-7 days to become detectable in hair.
• Expense: Hair drug tests are typically costlier than other drug testing procedures.
• Result disparities: Elements such as hair color and individual hair growth variability can affect the level of drug metabolites in the hair.

Note: Although often described as "hair follicle tests," the test examines the hair strand and not the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Laurel Hill, LA, hair follicle testing stands out as a superior option compared to urine tests. The enhanced detection accuracy of hair tests makes them a preferred choice, capturing drug use over an extended period with higher reliability.
