Hair Follicle Drug Testing - Mount Airy, MD

What it is, How it works

Hair analysis is increasingly recognized as an effective means for detecting drug and alcohol consumption. Over time, hair can encapsulate biomarkers of alcohol and drugs within its growing strands. When samples are taken near the scalp, they can reveal drug and alcohol usage over a period of roughly three months. Hair samples are straightforward to collect, challenging to tamper with, and convenient to send.

Obtaining a 1.5-inch segment comprising around 200 hair strands (comparable to a #2 pencil's thickness) nearest the scalp yields 100mg of hair, which is an ideal quantity for both screening and verification. For tests such as EtG or those exceeding 10 panels, 150mg of hair is advisable. It's suggested to measure the sample using a jeweler’s scale. If scalp hair is lacking, a similar quantity of body hair can be gathered. When mentioning head hair, it pertains solely to scalp hair. Conversely, body hair encompasses other hair types (facial, axillary, etc.).

Process Overview

The lab processing of drug test results involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially incorporated into the laboratory's system. This step ensures the sample was correctly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and fills in any additional data not supplied by electronic custody systems.

Screening is a preliminary assessment for drug presence. Although it's a cost-efficient method to exclude drug use in most samples, a positive screening necessitates confirmation to be legally valid. Samples with presumptive positive results in Screening need further confirmation.

If Screening suggests a positive result, more hair is extracted from the original sample for Extraction. Here, drugs are isolated from hair at much lower levels compared to other practices (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.

Confirmation of any positively screened result is done through GC/MS, GC/MS/MS, or LC/MS/MS. Positive samples are appropriately cleansed before confirmation. The full lab process from Accessioning through Confirmation adheres to both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests can uncover drug use up to 90 days, unlike urine tests with shorter detection windows.
• Hard to bypass: Cheating a hair drug test is extremely difficult, enhancing result accuracy.
• Tracks historical usage: It offers a timeline of drug use, rather than just recent consumption.

Limitations:

• Inability to spot recent use: Drugs become detectable in hair only after about 5-7 days.
• Expense: Hair testing tends to be pricier than alternative methods.
• Result variability: Drug metabolite levels in hair can be influenced by hair color and individual growth rates.

Note: Though often called "hair follicle tests", these examinations analyze the hair strand alone, excluding the follicle beneath the scalp.
