Hair Follicle Drug Testing - Milan, MO

What it is, How it works

Hair testing is now recognized as a valuable technique for identifying drug and alcohol use. Hair captures a long-term record of alcohol and other drugs by locking biomarkers within the fibers of the hair as it develops. When taken close to the scalp, hair can present a detection period of up to about 90 days for alcohol and other drugs. Hair collection is easy, relatively hard to tamper with, and straightforward to transport.

A sample of 1.5 inches comprising roughly 200 hair strands (comparable to the diameter of a #2 pencil) closest to the scalp provides 100mg of hair, the optimal quantity for analysis and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg quantity of the sample is advised. We suggest weighing the sample with a jeweler’s scale. If scalp hair cannot be used, a comparable quantity of body hair may be gathered. When we speak of head hair, we specifically mean scalp hair. Body hair pertains to all other types of hair (facial, axillary, etc.).

Process Overview

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

Accessioning refers to the initial integration of a sample into a lab’s system. This involves confirming that the sample was sealed and dispatched correctly, allocating a random LAN (Laboratory Accessioning Number), and finishing any extra data input not covered by an electronic chain of custody system.

Screening entails a preliminary rapid assessment for drugs of abuse. As Screening offers a cost-efficient method to exclude drug use on most samples, a positive screen must be confirmed for court admission. All samples that test presumptively positive during Screening necessitate secondary confirmation.

If a sample shows presumptive positivity at the Screening stage, additional hair is extracted from the original specimen and set for Extraction. In this stage, drugs are drawn out from hair at a substantially lower concentration than in alternative methodologies (e.g., urine or oral fluid), which is why hair drug screening is considered the most challenging methodology to execute.

Confirmation of any positive screen result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned prior to confirmation as necessary. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which offer a shorter detection window.
• Tough to manipulate: It's extremely challenging to falsify a hair drug test, ensuring greater accuracy in results.
• Delivers historical data: It presents a pattern of drug consumption over time, not merely recent use.

Limitations:

• Cannot detect very recent use: Drugs require around 5-7 days to become evident in hair.
• Expense: Hair drug tests generally cost more than alternative drug testing methods.
• Result variability: Factors like hair color and personal differences in hair growth may influence drug metabolite concentration in hair.

Note: Although commonly termed "hair follicle tests," the test analyzes the hair strand rather than the scalp hair follicle.

Why Hair Follicle Testing Beats Urine Testing
