Hair Follicle Drug Testing - Metcalfe, MS

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended retrospective insight into alcohol and drug intake by capturing biomarkers within the fibers of the hair as it grows. When obtained near the scalp, hair can reveal up to an estimated 3-month duration of alcohol and drug exposure. Hair's collection is straightforward, not easily tampered with, and is convenient for shipping.

An ideal sample comprises a 1.5-inch segment with roughly 200 hair strands (approximately the size of a #2 pencil) close to the scalp, providing about 100mg of hair, which is optimal for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, it is advised to utilize 150mg of the sample. The specimen should be weighed using a jeweler's scale. If scalp hair isn't available, a comparable quantity of body hair can be collected. Referring to head hair specifically denotes scalp hair. Body hair encompasses all other hair types (such as facial, axillary, etc.).

Process Overview

There are four primary steps in processing a lab drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning handles the initial processing of a sample into the lab's system. This step includes checking the sample's proper sealing and shipping, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any other data entry tasks not covered by an electronic chain of custody system.

Screening conducts an initial rapid evaluation for potential drugs. While it serves as a cost-efficient method to dismiss drug usage for most samples, positive results from Screening require further confirmation to be court-admissible. Any sample with a presumptively positive result from Screening needs a secondary confirmation.

Should a sample show presumptive positivity in Screening, more hair is extracted from the initial sample for Extraction preparation. At this stage, drugs are extracted from hair at concentrations far lower than other methods (such as urine or oral fluid), which makes hair drug screening the most challenging method to perform.

GC/MS, GC/MS/MS, or LC/MS/MS methods confirm positive screening results. All samples showing presumptive positivity are washed prior to necessary confirmations. The entire lab process from Accessioning to Confirmation falls under review, following both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection window: Hair drug tests can identify drug use up to 90 days, whereas urine tests have more limited detection durations.
• Hard to manipulate: Hair drug tests are challenging to deceive, ensuring greater accuracy of results.
• Offers historical insight: They provide drug use patterns over time, not limited to recent use alone.

Limitations:

• Cannot identify immediate use: It takes around 5-7 days before drugs become traceable in hair.
• Expense: Hair drug tests usually have a higher cost compared to other testing methods.
• Result variability: Factors including hair color and individual hair growth discrepancies may influence the drug metabolite concentration in hair.

Note: Commonly known as "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Metcalfe, MS, the debate between hair and urine testing often highlights hair's superior detection capability. Hair follicle testing can track substance use over a broader timeframe, capturing usage history better than urine tests.
