Hair Follicle Drug Testing - Collegeville, MN

What it is, How it works

Hair testing has gained recognition as a formidable method for identifying drug and alcohol usage. Hair captures a comprehensive record of alcohol and other drugs by embedding biomarkers within the strands of the growing hair. When hair is clipped near the scalp, it can reveal a detection period of up to 3 months for both alcohol and other drugs. The collection process for hair is straightforward, poses challenges to adulteration, and simplifies shipment.

A sample size of 1.5 inches, consisting of approximately 200 hair strands (equivalent to a #2 pencil in thickness) from near the scalp, yields 100mg of hair, the preferred quantity for both screening and confirmation. In cases of EtG, additional tests, and/or analyses exceeding 10 panels, a greater amount of 150mg is advised. Using a jeweler’s scale to weigh the specimen is suggested. When scalp hair is not available, a comparable quantity of body hair may be utilized. Reference to head hair exclusively pertains to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test results encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial input of a sample into a laboratory's database. The process involves checking the sample's proper sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry that an electronic chain of custody system has not addressed.

Screening constitutes an initial cursory examination for drugs of abuse. Although Screening offers a cost-efficient means to dismiss drug usage in most samples, any positive screen results demand confirmation to attain court admissibility. Samples that are presumptively positive during Screening necessitate additional confirmation.

A presumptive positive result during the Screening phase leads to additional hair being retrieved from the primary specimen for preparation for Extraction. This step involves isolating drugs from hair at a concentration significantly lower than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology.

Confirmation of positive screening outcomes is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples flagged as presumptive positive undergo washing before confirmation as required. The complete laboratory procedure, from Accessioning to Confirmation, aligns with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug consumption for up to 90 days, unlike urine tests which offer a shorter detection timeframe.
• Challenging to deceive: Cheating a hair drug test is exceedingly difficult, enhancing the precision of results.
• Captures historical trends: The test can illustrate a pattern of drug consumption over time, not merely recent usage.

Limitations:

• Inability to detect recent usage: It requires approximately 5-7 days for drugs to become identifiable in hair.
• Expense: Hair drug tests generally incur higher costs compared to other methods.
• Result variability: Elements like hair color and individual differences in hair growth can impact the concentration of drug metabolites within the hair.

Note: Although termed "hair follicle tests", this analysis examines the hair strand itself, excluding the follicle beneath the scalp.
