Hair Follicle Drug Testing - Egan, LA

What it is, How it works

Hair testing is increasingly recognized as a robust method for identifying drug and alcohol use. Hair essentially offers a historical record of alcohol and other drug intake by embedding biomarkers within the fibers of the growing hair strand. When collected from near the scalp, hair can cover up to a quarter-year timeframe for detecting alcohol and other drugs. Hair collection is straightforward, somewhat resistant to tampering, and simple to transport.

A 1.5-inch sample containing about 200 hair strands (approximately the same as a #2 pencil's width) nearest to the scalp provides 100mg of hair, which is the preferred sample size for both screening and confirmation. For EtG add-ons and/or for tests exceeding 10 panels, 150mg of the specimen is advisable. It's recommended to measure the sample using a jeweler’s scale. If scalp hair is not available, a similar quantity of body hair may be gathered. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other hair types such as facial and axillary hair.

Process Overview

The drug test result processing in the lab comprises four chief steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the first stage of processing a sample into a laboratory’s system. This involves checking that the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry not covered by an automated chain of custody system.

Screening involves a quick preliminary assessment for drugs of abuse. Although Screening is usually a cost-efficient approach to rule out drug use in most samples, a positive result in Screening needs confirmation to be legally valid. All samples that indicate a positive result in Screening require an additional confirmation test.

When a sample is tentatively positive in the Screening phase, additional hair is extracted from the initial specimen and readied for Extraction. At this point, drugs are extracted from hair at much lower concentrations than other testing methods (e.g., urine or oral fluid), which is why hair drug screening is considered the most challenging technique to execute.

Confirmation of a positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples undergo a washing cycle prior to the confirmation process, as necessary. The complete lab process from Accessioning to Confirmation is examined according to both the CAP (College of American Pathologists) Hair standards and the accreditation to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a reduced detection timeframe.
• Resistance to manipulation: It is significantly tough to falsify results in a hair drug test, enhancing the accuracy of outcomes.
• Offers historical insights: It can reveal a sequence of drug use across an extended period, not merely recent usage.

Limitations:

• Cannot confirm recent use: It takes around 5-7 days for drugs to be recognizable in hair.
• Expense: Hair drug screenings are generally costlier compared to other drug testing techniques.
• Result variability: Factors like hair color and individual differences in hair growth can impact the level of drug metabolites in the hair.

Note: Although commonly called "hair follicle tests", the test examines the hair strand rather than the follicle beneath the scalp.
