Hair Follicle Drug Testing - Westminster, MD

What it is, How it works

Hair testing has gained recognition as an effective method for detecting drug and alcohol consumption. Hair captures a history of substance use by embedding biomarkers within the fibers of the developing hair strand. When cut close to the scalp, hair can indicate drug and alcohol usage over a period of up to three months. It's straightforward to gather, relatively challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches with around 200 hair strands (roughly the diameter of a #2 pencil) nearest the scalp yields 100mg of hair, which is ideal for both screening and confirmation purposes. For EtG, additional tests, and/or assessments exceeding 10 panels, a specimen of 150mg is preferred. Utilizing a jeweler’s scale to measure the specimen is advised. If scalp hair cannot be obtained, a similar quantity of body hair may be used. When we reference head hair, we mean scalp hair exclusively. Conversely, body hair pertains to all other hair types (like facial, axillary, etc.).

Process Overview

The four essential phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary integration of a sample into a laboratory's system, confirming the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input not supplied by an electronic chain of custody system.

Screening is a preliminary, rapid assessment for signs of drug abuse. Although Screening is a cost-effective means of ruling out drug usage in most samples, a positive result necessitates confirmation to be valid in court. Any samples with presumptive positive findings in Screening require further confirmation.

Should a sample test presumptively positive during Screening, additional hair is extracted from the initial specimen for Extraction. Drugs are then extracted from hair at concentrations substantially lower than those found in other methodologies (such as urine or oral fluid), underscoring why hair drug testing is the most complex methodology to perform.

Confirmation of positive screening results is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptive positive are washed before confirmation as needed. The complete lab procedure, from Accessioning to Confirmation, 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 period: Hair drug tests can identify drug use for as long as 90 days, unlike urine tests which have a shorter detection time.
• Difficulty to manipulate: Cheating on a hair drug test is exceedingly difficult, leading to more precise results.
• Tracks historical usage: It can reveal a pattern of substance use over time, not just recent use.

Limitations:

• Inability to detect recent usage: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests tend to be more costly than other testing methods.
• Result variability: Elements like hair color and individual hair growth differences can impact drug metabolite concentration in hair.

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

Why Hair Follicle Testing Beats Urine Testing
