Hair Follicle Drug Testing - St. Clair, MI

What it is, How it works

Hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair retains a long-term history of alcohol and other substances by embedding biomarkers within the fibers of the growing hair strand. When taken near the scalp, hair can deliver up to an approximately 3-month detection timeframe for alcohol and other substances. It is easy to collect, relatively challenging to tamper with, and straightforward to transport.

A 1.5-inch segment of roughly 200 hair strands (equivalent to the size of a #2 pencil) nearest to the scalp will produce 100mg of hair, which is the ideal sample amount for screening and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of the sample is advisable. We suggest weighing the sample on a jeweler’s scale. If scalp hair is unavailable, a corresponding amount of body hair might be obtained. When mentioning head hair, we are specifically discussing scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning includes the initial incorporation of a sample into a laboratory’s system. This involves checking that the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not supplied by an electronic chain of custody system.

Screening encompasses a preliminary check for drugs of abuse. Although Screening is an economical method to exclude drug usage in most samples, a positive screen necessitates confirmation to be valid in court. Any samples indicative of a positive result in Screening require a secondary confirmation.

If a sample is indicative of a positive result in the Screening phase, additional hair is drawn from the initial sample and prepared for Extraction. During this phase, drugs are extracted from hair at considerably lower concentrations compared to other methods (ex. urine or oral fluid), making hair drug testing the most challenging method to execute.

Should a positive screening result occur, Confirmation is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicative of a positive result undergo washing before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests that have a more limited detection window.
• High difficulty to manipulate: It is extremely tough to alter a hair drug test, ensuring more reliable results.
• Tracks historical consumption: It provides a record of drug use over a time span, instead of merely recent consumption.

Limitations:

• Inability to identify recent consumption: It requires roughly 5-7 days for substances to become detectable within hair.
• Expense: Hair drug testing is typically higher in cost compared to other testing methods.
• Outcome variations: Elements like hair color and personal differences in hair growth can influence the concentration of drug metabolites within the hair.

Note: While frequently termed as "hair follicle tests", the actual test examines the hair strand and not the follicle beneath the scalp.
