Hair Follicle Drug Testing - Formosa, AR

What it is, How it works

Hair analysis is recognized as an effective means for identifying substance and alcohol consumption. Hair acts as a timeline, capturing evidence of alcohol and drug use within the structure of the developing hair fibers. When taken near the scalp, hair provides a detection window extending up to roughly 90 days for alcohol and drugs. Hair is straightforward to gather, relatively resistant to tampering, and simple to transport.

A sample of 1.5 inches consisting of around 200 hair strands (approximately the diameter of a #2 pencil) from the scalp yields 100mg of hair, the optimal amount for both primary screening and further confirmation. For EtG tests, additional analyses, or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest using a jeweler’s scale for weighing the sample. If scalp hair is not present, a comparable amount of body hair may be used. "Head hair" refers exclusively to scalp hair, whereas "body hair" encompasses all other body hair types (such as facial, underarm, etc.).

Process Overview

The laboratory process for processing a drug test result consists of four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into a lab's system, including ensuring the sample was properly sealed and dispatched, generating a unique LAN (Laboratory Accessioning Number), and completing any missing data entry that wasn't supplied by an electronic custody chain system.

Screening involves a preliminary rapid assessment for drugs. Screening offers a cost-efficient method to eliminate potential drug use in most samples, however, a positive screen must be confirmed for court admissibility. Any sample testing positive during Screening must undergo secondary confirmation.

When a sample tests positive in the Screening phase, additional hair is prepared from the initial sample for Extraction. This process extracts drugs at a much finer concentration from hair compared to other methods (like urine or saliva), making hair drug testing the most challenging method to conduct.

Confirmation of any positive result from screening is done through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Prior to Confirmation, all positive samples are cleaned as necessary. The comprehensive lab process from Accessioning through Confirmation is subject to review under both 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 reveal drug usage for up to 90 days, while urine tests have shorter detection periods.
• Hard to evade: Cheating on a hair drug test is exceptionally difficult, enhancing result accuracy.
• Historical insight: It delivers a timeline of drug usage over months, as opposed to just recent intake.

Limitations:

• Cannot detect recent use: Detection of drugs in hair takes about 5-7 days post-consumption.
• Cost: Hair drug testing is typically pricier than alternative screening methods.
• Result variability: Variables like hair color and personal hair growth rates can influence drug metabolite concentrations within hair.

Note: Although sometimes called "hair follicle tests," the test targets the hair strand, not the follicle beneath the scalp.
