Hair Follicle Drug Testing - Grandfather, NC

What it is, How it works

Hair testing is recognized as an effective means to detect drug and alcohol consumption. Hair encapsulates a comprehensive record of alcohol and other drug use by embedding biomarkers within the strands as they grow. When obtained near the scalp, hair can offer around a 3-month detection period for alcohol and drugs. The collection is straightforward, somewhat resistant to tampering, and simple to ship.

A sample measuring 1.5 inches containing about 200 hair strands (comparable to the diameter of a #2 pencil) close to the scalp will yield 100mg of hair, which is optimal for initial screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is suggested. We advise using a jeweler’s scale for accurate weighing. If scalp hair is not present, a comparable amount of body hair can be used. "Head hair" refers exclusively to scalp hair, whereas "Body hair" encompasses other types, such as facial and axillary hair.

Process Overview

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

During Accessioning, a sample undergoes initial processing within a lab system. This step ensures the sample was sealed and transported correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any pending data entry absent in an electronic chain of custody system.

Screening provides an initial rapid assessment for drug presence. Although it is cost-efficient to potentially eliminate drug use in most samples, any positive findings during screening necessitate confirmation to be legally valid. Samples testing presumptively positive in Screening need a secondary confirmation.

If a sample tests presumptively positive in the Screening phase, additional hair is extracted from the initial sample for the Extraction process. Here, drugs are isolated from hair at significantly lower concentrations than alternative methods like urine or oral fluid testing, contributing to the complexity of hair drug screening.

For confirming positive screenings, GC/MS, GC/MS/MS, or LC/MS/MS methods are deployed. Presumptive positive samples undergo washing as required before confirmation. The full laboratory process from Accessioning to Confirmation adheres to the standards set by both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug use for up to 90 days, unlike urine tests, which offer a shorter window.
• Hard to manipulate: Cheating a hair drug test is notably challenging, enhancing the reliability of results.
• Records past usage: It supplies a temporal pattern of drug consumption, rather than just recent intake.

Limitations:

• Inability to detect recent use: Approximately 5-7 days are needed for drugs to become traceable in hair.
• Expense: Generally, hair drug testing incurs higher costs compared to other testing methods.
• Result variations: Elements like hair color and individual differences in hair growth can impact drug metabolite concentration in hair.

Note: Although often named "hair follicle tests", the analysis focuses on the hair strand and not the follicle beneath the scalp.
