Hair Follicle Drug Testing - North Brentwood, MD

What it is, How it works

Hair analysis is now recognized as an effective method for detecting drug and alcohol consumption. Hair retains a long-term record of alcohol and drug intake by embedding markers within the strands of growing hair. When sampled near the scalp, hair can offer a detection period of up to approximately 3 months for alcohol and other substances. Collecting hair is straightforward, relatively tamper-resistant, and convenient to transport.

A sample of 1.5 inches, consisting of approximately 200 hair strands (about the thickness of a #2 pencil) closest to the scalp, yields 100mg of hair, the preferred sample size for both screening and confirmation. For EtG tests, add-ons, or screenings exceeding 10 panels, 150mg of the specimen is suggested. It is advisable to weigh the specimen using a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair may be utilized. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning entails the initial integration of a sample into a laboratory's system. This process includes ensuring the sample is properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry not included by an electronic chain of custody system.

Screening is a preliminary evaluation for drug abuse. Although it is a cost-effective method for excluding drug use in most samples, a positive screening result requires confirmation to be legally valid. Samples that are initially positive in Screening demand a secondary confirmation.

Should a sample test positive during the Screening phase, additional hair is used from the original specimen and readied for Extraction. At this stage, drugs are isolated from the hair at much lower concentrations than in alternative methods (e.g., urine or oral fluids), which is why hair drug screening is the most intricate methodology to execute.

Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All tentatively positive samples undergo washing before confirmation as necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is validated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug consumption up to 90 days, whereas urine tests have a shorter detection period.
• Resistant to deception: Hair drug tests are challenging to tamper with, resulting in more reliable results.
• Chronological data provision: It offers a usage pattern over time, rather than just recent usage.

Limitations:

• Inability to detect recent use: Drugs require about 5-7 days to become traceable in hair.
• Expense: Hair drug testing generally incurs higher costs than other testing methods.
• Result variability: Factors like hair color and personal hair growth variations can influence the level of drug metabolites found in hair.

Note: Even though it is often called a "hair follicle test," the analysis is conducted on the hair strand, not the follicle beneath the scalp.
