Hair Follicle Drug Testing - Twin Lakes, FL

What it is, How it works

Hair testing is now a recognized method for identifying the use of drugs and alcohol. Hair retains a historical imprint of alcohol and drug consumption by embedding biomarkers in the hair fiber as it grows. If collected near the scalp, hair can indicate alcohol and drug use within a window of about three months. Collection is straightforward, tampering is challenging, and transportation is uncomplicated.

A 1.5-inch segment consisting of approximately 200 hair strands (akin to the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for testing and confirmation. For EtG, additional testing, or panels exceeding 10, a sample weighing 150mg is advisable. Specimens should be measured using a jeweler’s scale. Should scalp hair not be available, a similar weight of body hair may be gathered. Head hair refers specifically to scalp hair, while body hair encompasses any other types (e.g., facial, axillary).

Procedure Summary

The drug testing laboratory process is composed of four principal stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially processed within a laboratory's system. This step includes confirming that the sample is properly sealed and shipped, generating a random LAN (Laboratory Accessioning Number), and fulfilling any missing data entry not covered by an electronic chain of custody.

Screening serves as a swift preliminary test for detecting drug abuse. Although Screening offers a cost-efficient means to eliminate drug use in most samples, a positive result requires confirmation for legal acceptability. Samples yielding a presumptive positive in Screening demand a confirmatory evaluation.

In cases where a sample shows a presumptive positive during Screening, additional hair is collected from the original sample for Extraction. Extraction involves retrieving drugs from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), establishing hair drug testing as a complex process.

Confirmation for any positive findings from Screening utilizes GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positives undergo a wash prior to confirmation as needed. The complete laboratory workflow from Accessioning through Confirmation undergoes examination under CAP (College of American Pathologists) Hair designation as well as ISO / IEC 17025 accreditation standards.

Benefits of Hair Drug Testing:

• Extended detection period: Hair drug testing can reveal drug use up to 90 days, surpassing the shorter window of urine testing.
• Challenge in falsification: Tampering with hair drug tests is substantially difficult, ensuring higher accuracy.
• Historical drug use insight: The test indicates a pattern of drug usage over time, surpassing detection of recent use alone.

Drawbacks:

• Inability to detect recent use: Drugs can be identified in hair roughly 5-7 days post-consumption.
• Expense: Hair drug tests typically incur higher costs compared to alternative testing methods.
• Result variability: Factors such as hair coloration and personal hair growth rates may impact drug metabolite levels in hair.

Note: While commonly termed "hair follicle tests", the analysis is performed on the hair strands themselves, not on the follicles beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
