Hair Follicle Drug Testing - Unionville, VA

What it is, How it works

Hair analysis is acclaimed as an effective method for identifying drug and alcohol consumption. Hair acts as a repository of alcohol and drug use history by capturing biomarkers within the fibers of the hair as it grows. When hair is collected near the scalp, it offers a detection timeframe of up to about three months for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and easy to send.

A 1.5-inch snippet of roughly 200 hair strands (approximately the diameter of a #2 pencil) closest to the scalp yields 100mg of hair, which is the preferred amount for analysis and validation. For EtG, additional tests, and anything exceeding 10-panel tests, 150mg of the sample is suggested. We advocate for weighing the sample on a jeweler’s scale. In cases where scalp hair can't be accessed, an equivalent quantity of body hair may be gathered. "Head hair" refers exclusively to scalp hair. "Body hair" denotes all other types of hair (like facial, underarm, etc.).

Process Overview

The core stages in the laboratory procedure for processing a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into a lab’s system. This step includes ensuring that the sample is sealed and transported correctly, allocating a random LAN (Laboratory Accessioning Number), and concluding any remaining data entry not covered by an electronic chain of custody system.

Screening serves as an initial swift assessment for drug misuse. While Screening economically eliminates drug use for most samples, any positive results necessitate validation to be permissible legally. Samples that yield presumptively positive results in Screening demand a follow-up confirmation.

Should a sample appear presumptively positive during the Screening phase, extra hair is sourced from the original sample for Extraction. In this phase, drugs are retrieved from hair at a much lower concentration compared to other techniques (such as urine or oral fluid), which is why hair drug testing presents the most complex methodology to execute.

Validation of any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, any presumptively positive sample is cleansed as necessary. The comprehensive lab workflow from Accessioning to Confirmation is examined according to the CAP (College of American Pathologists) Hair designation as well as the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover drug use for as long as 90 days, as opposed to urine tests which have a shorter detection span.
• Hard to falsify: It is notably challenging to bypass a hair drug test, ensuring more reliable outcomes.
• Supplies historical information: It can exhibit a history of drug usage over a timeframe, not merely recent usage.

Limitations:

• Inability to identify recent use: It typically requires 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests usually cost more than other drug testing techniques.
• Differences in outcomes: Elements like hair color and individual discrepancies in hair growth can influence drug metabolite concentration in the hair.

Note: Commonly known as "hair follicle tests", this test actually examines the hair strand rather than the hair follicle beneath the scalp
