Hair Follicle Drug Testing - Guilford, PA

What it is, How it works

Hair testing is increasingly acknowledged as an effective approach for identifying drug and alcohol usage. Hair retains a prolonged history of substance consumption by embedding biomarkers within the strands as they grow. When taken near the scalp, hair can present a detection period of up to roughly 90 days for alcohol and substances. Hair is easy to collect, challenging to tamper with, and simple to transport.

A 1.5-inch segment of approximately 200 hair strands (comparable in size to a #2 pencil) adjacent to the scalp will yield 100mg of hair, the ideal quantity for analysis and verification. For EtG, additional tests, and/or assessments exceeding 10 panels, 150mg of the sample is suggested. We advise utilizing a jeweler’s scale to measure the sample's weight. If scalp hair is not obtainable, an equivalent quantity of body hair may be collected. When referring to 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 consists of four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a sample into a lab's system. This process involves verifying that the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry required beyond what an electronic chain of custody system provides.

Screening involves an initial swift examination for substance misuse. Although Screening offers a cost-effective means to exclude drug use in most samples, a positive screen needs confirmation for legal admissibility. Any samples that test presumptively positive in Screening necessitate a further confirmation.

If a sample is deemed presumptively positive in the Screening phase, additional hair is taken from the original sample and prepared for Extraction. In this phase, substances are drawn from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), which is why hair analysis is the most challenging testing method to execute.

Confirmation of any positive screening results is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation where necessary. The entire laboratory process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use for up to 90 days, as opposed to urine tests with shorter detection spans.
• Hard to manipulate: Cheating a hair drug test is extremely challenging, hence the results are more reliable.
• Offers historical insights: It can reflect a drug usage pattern over time, beyond just recent consumption.

Limitations:

• Inability to detect recent use: About 5-7 days are needed for substances to become traceable in hair.
• Expense: Hair drug tests are typically pricier than other drug testing techniques.
• Outcome variations: Elements like hair color and personal differences in hair growth can influence the drug metabolite concentration in hair.

Note: Commonly termed as "hair follicle tests", the analysis actually focuses on the hair strand and not the follicle underneath the scalp
