Hair Follicle Drug Testing - Christiana, PA

What it is, How it works

Recognized as an effective method for identifying drug and alcohol consumption, hair testing captures a lengthy history of substance use by locking biomarkers within the strands of hair as it grows. When collected from near the scalp, hair offers insights into alcohol and drug intake for up to three months. The collection of hair is straightforward, hard to tamper with, and easy to transport.

Obtaining a 1.5-inch segment from around 200 hair strands (akin to a #2 pencil's size) nearest the scalp yields 100mg of hair, which is the preferred amount for testing and verification. For EtG, extended tests, or tests beyond 10 panels, a sample of 150mg is advisable. It is suggested to weigh the sample using a jeweler's scale. If scalp hair cannot be collected, an equivalent quantity of body hair can be used. “Head hair” pertains specifically to scalp hair; “body hair” refers to all other types of hair (e.g., facial, axillary).

Process Overview

The procedure for processing drug test results in a laboratory includes four key stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially registered in a laboratory's system. Steps include ensuring the sample's proper sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data entry not handled by an electronic custody system.

Screening conducts a swift preliminary evaluation for substance abuse. While it is a budget-friendly method to exclude drug usage in most samples, a positive screen necessitates confirmation to be used in legal settings. Samples with a presumptive positive result in Screening do need further verification.

When a sample shows a presumptive positive result in the Screening step, additional hair is extracted from the initial sample and readied for Extraction. At this stage, substances are extracted from hair at a concentrations lower than in urine or oral fluid, thus making hair drug screening the most challenging method to execute.

Verification of any positive screening outcomes is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. The entire laboratory process from Accessioning through Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can detect substance use for up to 90 days, as opposed to urine tests with a much shorter detection timeframe.
• Hard to manipulate: Cheating a hair drug test is highly challenging, increasing the accuracy of results.
• Historical data provision: They offer a pattern of drug usage over a duration, not just recent use.

Limitations:

• Inability to identify recent use: It usually takes 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests tend to be costlier than other testing techniques.
• Results variations: Factors like hair color and individual hair growth variations can impact drug metabolite concentration in the hair.

Note: Although frequently called "hair follicle tests", the assessment analyzes the hair strand and not the follicle beneath the scalp.
