Hair Follicle Drug Testing - Derma, MS

What it is, How it works

Hair testing is now acknowledged as an effective method for identifying drug and alcohol consumption. Hair captures biomarkers within the strands as it grows, thus it offers a comprehensive record of alcohol and drug use. By collecting samples close to the scalp, it is possible to detect alcohol and drugs for nearly three months. Collecting hair is straightforward, tampering is challenging, and it can be transported easily.

To acquire a 1.5-inch hair sample approximately the size of a #2 pencil, around 200 strands should be gathered from the area nearest the scalp, yielding 100mg, the preferred amount for both screening and verification. If testing for EtG, additional testing, and/or over 10 panels, a specimen of 150mg is advisable. Using a jeweler's scale for weighing is suggested. If scalp hair cannot be retrieved, a comparable quantity of body hair may be used. When discussing head hair, it pertains solely to scalp hair, whereas body hair includes all other types (such as facial, axillary, etc.).

Process Overview

The core stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning means the sample is entered into the lab’s system for initial processing. This step involves checking that the sample is properly sealed and transported, assigning it a unique LAN (Laboratory Accessioning Number), and inputting any missing data not supplied by an electronic chain of custody system.

Screening performs a preliminary evaluation for abuse drugs. It is a budget-friendly approach for identifying the absence of drug usage in most samples. However, a positive screening result needs validation to be recognized in court. Thus, any presumptive positive results from the Screening require subsequent verification.

Upon finding a presumptive positive in the Screening phase, more hair is sourced from the original sample for Extraction. Here, drugs are retrieved from hair at significantly lower concentrations than other techniques (such as urine or oral fluid), establishing hair drug screening as the most complex method to execute.

Positive results from screenings are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Before verification, all presumptive positive samples undergo washing as needed. The entire lab process from Accessioning to Confirmation adheres to the CAP (College of American Pathologists) standards for Hair, as well as ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for as many as 90 days, whereas urine tests offer a shorter detection period.
• Hard to tamper with: The intricacies of cheating hair drug tests render the results highly reliable.
• Historical insights: These tests provide drug use patterns over time, unlike tests focusing only on recent use.

Limitations:

• Inability to recognize recent use: Drugs become detectable in hair roughly 5-7 days post-consumption.
• Expense: Generally, hair drug tests cost more relative to other testing methods.
• Result variations: Influences like hair color and individual hair growth can alter drug metabolite levels in the hair.

Note: Although often termed "hair follicle tests", the procedure examines the hair strand, not the follicle located beneath the scalp.
