Hair Follicle Drug Testing - Crossville, IL

What it is, How it works

Hair testing is increasingly perceived as a crucial method for identifying drug and alcohol consumption. Hair captures a long-standing record of alcohol and drug use by embedding biomarkers within the strands of growing hair. When sampled near the scalp, hair offers a detection period of up to about 3 months for alcohol and drugs. Collecting hair is uncomplicated, relatively hard to tamper with, and convenient to transport.

A 1.5-inch portion of roughly 200 hair strands (akin to a #2 pencil's diameter) nearest the scalp yields 100mg of hair, the prime sample size for screening and confirmation. For EtG, additional screens, and/or tests exceeding 10 panels, a specimen size of 150mg is advised. It is recommended to use a jeweler’s scale to measure the specimen weight. Should scalp hair be unavailable, an equivalent quantity of body hair can be used. "Head hair" is specifically scalp hair, while "body hair" pertains to all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial introduction of a sample into the lab system. This phase ensures the sample's proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any additional information entry not covered by an electronic chain of custody system.

Screening offers an initial rapid inspection for drugs of misuse. While cost-efficient for ruling out drug usage in most samples, positive screens require confirmation to be legally valid. Samples showing presumptive positive results in Screening necessitate another confirmation step.

If Screening suggests a presumptive positive, more hair is extracted from the initial sample for the Extraction stage. Here, drugs are removed from hair at much lower concentrations than other methods (e.g., urine, oral fluid), making hair drug screening a particularly challenging methodology to execute.

Confirmation of any positive Screening results happens via GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples are washed as necessary before confirmation. The complete lab process, from Accessioning to Confirmation, adheres to the CAP (College of American Pathologists) Hair guidelines and the accreditation of ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection span: Hair drug tests identify drug use for up to 90 days, whereas urine tests have a narrower detection span.
• Resistance to manipulation: Hair drug tests are challenging to deceive, resulting in more precise outcomes.
• Offers historical insights: They reveal a timeline of drug use over time, not just recent activity.

Limitations:

• Ineffectiveness for recent use detection: It takes about 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests tend to be pricier than other drug testing techniques.
• Variation in outcomes: Aspects like hair color and personal differences in hair growth can alter the drug metabolite concentration in hair.

Note: Although commonly termed "hair follicle tests," the analysis is performed on the hair strand, not on the under-skin hair follicle.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Crossville, IL, consistently outshines urine testing by providing superior detection accuracy. While urine tests are more traditional, the comprehensive analysis of hair samples offers a longer detection window.
