Hair Follicle Drug Testing - Siloam Springs, AR

What it is, How it works

Seen as an effective method, hair testing is essential for identifying drug and alcohol consumption. The fibers of growing hair strands encapsulate biomarkers, offering an extended history of alcohol and drugs. Collecting hair close to the scalp enables a detection window up to roughly three months. Hair collection is straightforward, hard to tamper with, and easy to transport.

A sample comprising a 1.5-inch section of about 200 hair strands (comparable to the size of a #2 pencil) near the scalp results in 100mg of hair, which is the perfect sample size for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is suggested. Utilizing a jeweler’s scale for weighing the sample is recommended. In the absence of scalp hair, an equivalent amount of body hair could be used. In this context, head hair refers exclusively to scalp hair. Body hair refers to all other types of hair (e.g., facial, axillary).

Process Overview

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

Accessioning constitutes the primary handling of the sample into the laboratory’s framework. This step includes verifying the sample’s sealing and shipping status, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent in an electronic chain of custody system.

With Screening, there’s an initial fast check for drugs. Though cost-effective for eliminating drug usage in most samples, a positive screen needs confirmation for court admissibility. Samples presumed positive during Screening require a secondary confirmation.

Should a sample indicate a presumptive positive during Screening, additional hair is extracted from the original specimen for the Extraction phase. In this phase, the drugs are extracted from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation of any positive screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples presumed positive are washed before confirmation based on necessity. The whole laboratory method from Accessioning right through to Confirmation is rigorously analyzed under the CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can trace drug use for as long as 90 days, unlike urine tests that have a limited detection timeframe.
• Difficult to manipulate: Cheating on a hair drug test is extremely challenging, ensuring more precise results.
• Delivers historical insight: It presents a pattern of drug usage over a timeframe and not just recent ingestion.

Limitations:

• Incapable of detecting recent intake: Drugs take around 5-7 days to become traceable in hair.
• Expense: Hair drug tests generally incur higher costs than alternative drug testing methods.
• Result variability: Factors such as hair color and individual growth patterns can alter the concentration of drug biomarkers in the hair.

Note: Even though termed "hair follicle tests", the analysis targets the hair strand rather than the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Siloam Springs, AR

Hair follicle testing offers a superior alternative to traditional urine tests due to its enhanced detection and reliability.
