Hair Follicle Drug Testing - Frederick, MD

What it is, How it works

Hair testing is recognized as a formidable instrument for identifying drug and alcohol consumption. Hair retains a prolonged evidence of alcohol and drug usage by encasing biomarkers within the hair strand's fibrous structure. When sampled near the scalp, hair can indicate a detection period of around three months for alcohol and drugs. The method is straightforward in collection, challenging to tamper with, and uncomplicated to mail.

A sample measuring 1.5 inches of roughly 200 hair strands (equivalent to a #2 pencil's thickness) closest to the scalp yields 100mg of hair, which is optimal for analysis and verification. For EtG, supplementary tests, or panels exceeding ten, a sample of 150mg is suggested. It is advisable to measure the sample on a jeweler's scale. In the absence of scalp hair, an equivalent quantity of body hair is acceptable. Reference to head hair specifies scalp hair uniquely, whereas body hair encompasses all other hair types (e.g., facial, axillary).

Process Overview

The lab processing of drug tests encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to initially interfacing a specimen with a laboratory’s framework. This step guarantees the specimen's proper sealing and dispatch, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any leftover data input not furnished by an electronic custody chain system.

Screening entails a preliminary rapid assessment for drug use. While cost-efficient in excluding drug use across most specimens, a positive Screening result necessitates verification for court validity. Samples yielding an initial positive in Screening must undergo additional confirmation.

Should a sample present a positive result during the Screening phase, further hair is extracted from the original sample for the Extraction phase. Herein, drug substances are isolated from hair at significantly diminished concentrations compared to other approaches (e.g., urine or oral fluid), rendering hair drug testing notably challenging.

Any positive results necessitate confirmation through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed preceding confirmation if required. The complete laboratory protocol, from Accessioning through Confirmation, adheres to the guidelines of both the CAP (College of American Pathologists) Hair category and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug testing can reveal drug intake for as long as 90 days, whereas urine testing has a more limited detection span.
• Minimal susceptibility to deception: Cheating a hair drug test is notably challenging, thereby enhancing the accuracy of results.
• Tracks historical drug use data: It offers an overview of drug consumption patterns over time, as opposed to only recent usage.

Limitations:

• Inability to identify recent intake: Drugs are detectable in hair only after approximately 5-7 days.
• Expense: Hair drug testing tends to be more costly compared to other drug testing methodologies.
• Result disparity: Factors like hair shade and individual hair growth differences can influence drug metabolite levels in the hair.

Note: Commonly called "hair follicle tests", the actual analysis targets the hair strand, not the follicle beneath the scalp.
