Hair Follicle Drug Testing - Severn, MD

What it is, How it works

The use of hair testing has increasingly been recognized as an effective method for identifying drug and alcohol consumption. Hair retains drug and alcohol indicators by embedding them in the strands' fibers as they grow. When hair is collected close to the scalp, it provides a detection span of up to three months for these substances. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.

A 1.5-inch section consisting of roughly 200 hair strands (akin to the width of a #2 pencil) taken next to the scalp yields 100mg of hair, which is optimal for testing purposes. For EtG, additional tests, or testing exceeding 10 panels, a 150mg sample is preferred. Using a jeweler's scale to weigh the sample is suggested. If scalp hair is not accessible, an equal portion of body hair may be used. When mentioning head hair, it specifically refers to scalp hair. Conversely, body hair encompasses all other types (including facial, axillary, etc.).

Process Overview

The laboratory processing of drug test samples unfolds in four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises entering a sample into a laboratory's records. Key tasks include confirming that the sample is intact and correctly transported, assigning a Laboratory Accessioning Number (LAN), and performing any supplementary data tasks absent from an electronic custody system.

Screening conducts a preliminary assessment for substance abuse indicators. Although Screening offers a budget-friendly solution that negates drug presence in most cases, any positive findings must undergo confirmation for legal admissibility. Samples that appear positive in Screening phase necessitate an additional verification process.

Should a sample present positive signs during Screening, further hair is taken from the initial supply for Extraction. Here, drugs are gleaned from hair in significantly lower concentrations compared to alternative methods (like urine or saliva), making hair testing one of the most intricate techniques.

Any preliminary positive findings proceed to Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Pre-confirmation cleansing is performed on samples as necessary. The complete lab process, from Accessioning to Confirmation, is scrutinized under both CAP's Hair standards and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection span: Hair tests identify drug use for as long as 90 days, unlike urine tests which have a shorter detection window.
• Hard to manipulate: The likelihood of cheating a hair test is minimal, ensuring more reliable outcomes.
• Supplies historical patterns: It not only captures recent drug use but also offers a historical usage pattern.

Limitations:

• Cannot identify recent use: It takes around 5-7 days for drugs to surface in hair.
• Expense: Hair tests typically cost more than other drug testing approaches.
• Result variability: Drug metabolite levels in hair could vary due to factors like hair color and individual hair growth rate.

Note: Though termed "hair follicle tests," the examination actually involves the hair strand, not the follicle beneath the scalp.
