Hair Follicle Drug Testing - De Ridder, LA

What it is, How it works

Hair analysis is increasingly recognized as an effective means for detecting substance and alcohol consumption. The hair retains a record of alcohol and drug use, capturing biomarkers within the fiber strands. When obtained close to the scalp, hair offers a detection period of up to around three months for alcohol and other substances. It is straightforward to gather, somewhat resistant to tampering, and simple to transport.

A sample of 1.5 inches, consisting of approximately 200 hair strands (roughly the size of a #2 pencil) near the scalp, yields 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional substances, and/or tests exceeding 10 panels, 150mg of specimen is advisable. Using a jeweler’s scale to weigh the specimen is suggested. If scalp hair isn't available, a comparable quantity of body hair may be collected. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

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

Accessioning involves the sample's initial entry into a lab's system. This process ensures the sample was sealed and transported correctly, a random LAN (Laboratory Accessioning Number) is assigned, and any extra data entry not available through an electronic chain of custody system is completed.

Screening is a preliminary evaluation to detect drug use. Although Screening is an economical way to eliminate drug use in most samples, a positive result requires confirmation to be valid in court. Samples that are tentatively positive in Screening necessitate a secondary confirmation.

If the Screening phase indicates a presumptive positive, more hair is drawn from the original specimen and readied for Extraction. Here, drugs are extracted from the hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging technique.

Verification of any positive screening outcome is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if necessary. The entire lab process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair standard and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a shorter detection span.
• Difficult to cheat: Hair drug tests are hard to manipulate, yielding more precise results.
• Provides historical data: It offers a timeline of drug use over a duration, not just recent usage.

Limitations:

• Incapable of detecting recent use: It takes about 5-7 days for drugs to become apparent in hair.
• Expense: Hair drug tests typically cost more than other drug screening methods.
• Result variations: Factors like hair color and individual hair growth differences can influence drug metabolite concentrations in the hair.

Note: While commonly termed "hair follicle tests", the examination itself focuses on the hair strand, not the follicle beneath the scalp.
