Hair Follicle Drug Testing - Foreston, MN

What it is, How it works

Hair analysis is recognized as a robust method for identifying drug and alcohol consumption. Hair captures biomarkers in its fibers, presenting a comprehensive record of substance use over time. When obtained near the scalp, hair offers up to a 3-month detection period for substances like alcohol and drugs. Hair samples are easy to collect, challenging to adulterate, and simple to transport.

A 1.5-inch segment of roughly 200 hair strands (resembling the diameter of a #2 pencil) closest to the scalp provides 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, 150mg of hair is preferred. We advise weighing the hair sample using a jeweler's scale. If scalp hair isn't available, a comparable quantity of body hair may be used. In terms of head hair, we specifically mean scalp hair. Body hair signifies all other types of hair (e.g., facial, axillary).

Process Overview

The laboratory test result process involves four central steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is incorporated into a lab's workflow. This step involves confirming the correct sealing and shipping of the sample, generating a random LAN (Laboratory Accessioning Number), and completing missing data entry that isn't covered by an electronic chain of custody system.

Screening acts as a preliminary assessment for drug presence. Although Screening is an economical method for dismissing drug use in most samples, a positive Screening outcome must be confirmed for legal acceptance. Any samples that yield positive in Screening necessitate further confirmation.

For any specimen testing positive in Screening, additional hair is extracted from the sample for further processing in Extraction. In this phase, drug substances are extracted from hair at a substantially lower concentration compared to other methods (e.g., urine or oral fluid), establishing hair drug testing as the most complex method to execute.

Confirmation of any positive results from Screening is conducted using GC/MS, GC/MS/MS or LC/MS/MS. Before confirmation, all presumptive positive specimens are cleaned as required. The full laboratory process, from Accessioning through Confirmation, is assessed according to both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests detect drug use for up to 90 days versus urine tests with shorter windows.
• Hard to falsify: Cheating on a hair drug test is notably difficult, resulting in more reliable outcomes.
• Provides usage trends: It can outline drug use patterns over an extended timeframe, not merely recent consumption.

Limitations:

• Cannot identify recent use: Drugs typically become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests are often pricier than alternative testing methods.
• Result variability: Elements like hair color and individual growth variations may impact drug metabolite concentration in hair.

Note: Commonly called "hair follicle tests", the analysis actually reviews the hair strand rather than the follicle beneath the scalp.
