Hair Follicle Drug Testing - Midlothian, MD

What it is, How it works

Hair testing has emerged as an integral method for identifying drug and alcohol consumption. The structure of hair allows it to encapsulate markers of substances in the strands as they grow, providing a detailed history of alcohol and drug use. When hair is collected near the scalp, it offers a detection period of up to roughly three months for both alcohol and drugs. Collection of hair is straightforward, somewhat resistant to tampering, and convenient for transportation.

A sample measuring 1.5 inches composed of around 200 hairs (approximately the thickness of a #2 pencil) close to the scalp yields 100mg of hair, which is the preferred quantity for examination and validation. For EtG, supplementary tests, or testing beyond 10 panels, a sample of 150mg is advised. Using a jeweler’s scale to weigh the specimen is recommended. If scalp hair cannot be collected, an equivalent amount of body hair may be used. When mentioning head hair, we are exclusively referring to scalp hair. Body hair encompasses all other types of hair (such as facial or axillary).

Process Overview

The core steps in processing a drug test in a laboratory include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of processing a sample's entry into a lab's system. This step verifies proper sealing and shipping of the sample, assigns a unique LAN (Laboratory Accessioning Number), and finishes any additional data entry if an electronic chain of custody system is not used.

Screening is a preliminary rapid test for drugs of abuse. Though Screening is an economical method to negate drug use in most samples, a positive outcome requires confirmation to be court-admissible. Samples that test presumptively positive during Screening undergo further validation.

If Screening reveals a presumptive positive result, additional hair from the initial sample is prepared for Extraction. During this phase, drugs are isolated from the hair at concentrations lower than other tests (such as urine or oral fluid), making hair drug testing particularly challenging.

Confirmation of any positive from screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed before confirmation if necessary. The full laboratory process from Accessioning to Confirmation adheres to the standards of the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, whereas urine tests offer a more limited detection period.
• Hard to falsify: Since altering a hair drug test is particularly challenging, the results are more dependable.
• Provides usage history: It can show a drug consumption pattern over time rather than just recent usage.

Limitations:

• Cannot detect recent use: Drugs typically appear in hair after an approximate period of 5-7 days.
• Expense: Hair drug tests tend to be more costly than other testing methods.
• Result variations: Factors such as hair color and individual differences in hair growth impact the levels of drug markers in hair.

Note: Although frequently called "hair follicle tests", the test evaluates the hair shaft and not the follicle underneath the scalp.
