Hair Follicle Drug Testing - Glasgow, OR

What it is, How it works

Hair testing is increasingly perceived as a robust method for identifying drug and alcohol usage. By capturing biomarkers within the hair's growing strand fibers, it offers a long-term record of these substances. When obtained near the scalp, hair can reveal substance use within a roughly three-month timeframe for drugs and alcohol. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.

A 1.5-inch segment of approximately 200 hair strands (around the width of a #2 pencil) at the scalp can yield 100mg, the optimal amount for screening and confirmation. For EtG tests, additional panels, and tests exceeding 10 panels, 150mg is advisable. Using a jeweler’s scale to weigh the specimen is recommended. If head hair is not an option, a comparable quantity of body hair can be collected. "Head hair" refers specifically to scalp hair, whereas "body hair" encompasses other types (facial, axillary, etc.).

Process Overview

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

During Accessioning, a sample is initially processed into the laboratory system. This step includes ensuring the sample’s proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary additional data entry not covered by an electronic chain of custody system.

Screening constitutes an initial rapid check for substance abuse. While cost-efficient in ruling out drug use in most samples, any positive screen requires confirmation to be legally valid. Samples with presumptive positive results in Screening must undergo secondary confirmation.

When a sample yields a presumptive positive during Screening, more hair is taken from the original sample and readied for Extraction. In Extraction, substances are retrieved from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), making hair drug screening one of the more complex methodologies to execute.

Positive screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before confirmation if necessary. From Accessioning through Confirmation, the lab process is reviewed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug consumption for up to 90 days, unlike urine tests, which have a reduced detection period.
• Resistant to tampering: Cheating a hair drug test is extremely difficult, thus enhancing the accuracy of the results.
• Reflects historical use: It can illustrate a pattern of substance use over time, rather than just recent consumption.

Limitations:

• Cannot detect current use: Drugs take about 5-7 days to become detectable in hair.
• Cost: Typically, hair drug tests are pricier than other drug testing methods.
• Potential result variations: Factors like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Despite being termed "hair follicle tests," the analysis is conducted on the hair strand, not the follicle beneath the scalp.
