Hair Follicle Drug Testing - Pleasant Hill, PA

What it is, How it works

Hair testing is now recognized as an effective means for detecting drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug use by embedding biomarkers within the fibers of the hair as it grows. When taken near the scalp, hair can offer roughly a 3-month detection period for alcohol and drugs. The collection of hair is straightforward, hard to tamper with, and simple to send.

A 1.5-inch segment comprising about 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for analysis and verification. For EtG, additional tests, or tests exceeding 10 panels, 150mg of hair is suggested. It's advisable to weigh the hair on a jeweler’s scale. If there is no scalp hair, an equivalent quantity of body hair can be acquired. When discussing head hair, we mean scalp hair solely. Body hair includes all other types of hair (facial, axillary, etc.).

Process Overview

There are four primary steps in the laboratory analysis of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial intake and processing of a sample into a laboratory’s operations. This step ensures the sample was properly sealed and sent with care, assigns a random LAN (Laboratory Accessioning Number), and completes additional data not captured by an electronic chain of custody system.

Screening consists of an initial rapid examination for substances of abuse. Although Screening is a cost-efficient method to rule out drug usage in most samples, a positive screen must be verified to be considered valid in court. Samples showing presumptive positivity in Screening require a further confirmation.

If a sample is found to be presumptively positive in the Screening stage, more hair is obtained from the original sample and prepared for Extraction. At this stage, drugs are extracted from the hair at a considerably reduced concentration compared to other techniques (e.g., urine or oral fluid), making hair drug screening the most challenging technique to perform.

Confirmation of any positive screening outcome is performed through GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positivity are cleansed as necessary before confirmation. The laboratory processes from Accessioning to Confirmation undergo scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditations.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a shorter detection span.
• Difficult to falsify: Cheating a hair drug test is notably difficult, ensuring more precise outcomes.
• Historical use insights: It can reveal a pattern of drug use over time instead of merely recent use.

Limitations:

• Incapable of detecting recent use: Drugs take around 5-7 days to become traceable in hair.
• Expense: Generally, hair drug tests are more costly compared to other drug testing techniques.
• Result variability: Hair color and individual growth differences can influence the levels of drug metabolites in the hair.

Note: Often termed as "hair follicle tests", the examination focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
