Hair Follicle Drug Testing - Londontowne, MD

What it is, How it works

Hair analysis has emerged as an effective resource for identifying the use of substances like drugs and alcohol. The strands of hair encapsulate biomarkers within their fibers, offering a comprehensive timeline of usage. Sampling hair near the scalp can yield a detection range spanning up to three months for alcohol and drugs. Collecting hair is straightforward, fairly immune to tampering, and simple to transport.

A section of hair measuring 1.5 inches, roughly equating to the thickness of a #2 pencil and consisting of about 200 strands, yields 100mg—ideal for both initial and confirmatory tests. For advanced screenings, such as EtG add-ons or tests exceeding 10 panels, a 150mg sample is advised. Utilizing a jeweler’s scale to weigh the specimen is recommended. If scalp hair is not obtainable, an equivalent quantity of body hair can be used. When mentioning head hair, it specifically pertains to scalp hair, while body hair encompasses all other types (like facial or axillary hair).

Process Overview

The primary stages in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning begins with integrating a sample into the laboratory framework. This process involves confirming proper sealing and shipment of the sample, allocating a LAN (Laboratory Accessioning Number) randomly, and finalizing any supplementary data entry outside the scope of an electronic chain of custody system.

Screening serves as an initial measure to swiftly check for substance abuse. While it proves cost-saving for the majority, any positive results identified here must be confirmed for court admissibility. Samples showing presumptive positives require subsequent verification.

When a sample is flagged as presumptively positive during Screening, additional hair from the original sample is readied for Extraction. Here, drugs are extracted from the hair at far lower concentrations compared to other methods (e.g., urine or saliva), highlighting the complexity of hair drug testing.

Confirmation for any samples that screen positive is executed using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Samples preliminarily identified as positive undergo necessary washing before confirmation. The entire lab process, from Accessioning through Confirmation, is audited under the CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair tests reveal drug use for up to 90 days, whereas urine tests cover shorter time frames.
• Resistance to tampering: Hair drug tests are challenging to tamper with, enhancing result reliability.
• Chronic usage patterns: They can chart drug use patterns over time, unlike tests showing recent usage only.

Limitations:

• Cannot identify recent usage: It requires around 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug testing generally incurs higher costs than other methods.
• Result variability: Factors like hair coloration and individual growth differences can affect drug metabolite concentration in the hair.

Note: Commonly termed "hair follicle tests", these tests actually examine the hair strand itself, not the follicle beneath the scalp.
