Hair Follicle Drug Testing - Clear Spring, MD

What it is, How it works

Hair analysis has evolved into a significant mechanism for identifying alcohol and drug consumption. It offers an extended timeline of substance usage by encasing biomarkers within the strands of developing hair. When gathered from near the scalp, hair can reveal a detection span of nearly three months for both alcohol and drugs. Collecting hair is uncomplicated, fairly resistant to tampering, and straightforward to ship.

A sample measuring 1.5 inches consisting of roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, the preferred quantity for both screening and confirmation. For EtG, supplementary tests, or panels exceeding ten, 150mg of the sample is advised. It's suggested to measure the sample using a jeweler's scale. Should scalp hair be missing, a comparable amount of body hair can be gathered. When discussing head hair, it pertains strictly to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The four essential phases in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the primary handling of a sample within a lab's system. This process confirms that the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent from an electronic chain of custody system.

Screening entails an initial rapid evaluation for drug abuse. Although Screening is a cost-effective strategy for excluding drug usage in most samples, a positive screen must be confirmed to be deemed admissible in legal proceedings. Any samples showing preliminary positive results in Screening necessitate an additional confirmation.

Should a sample indicate a presumptive positive result during Screening, more hair is extracted from the original sample and prepared for Extraction. Here, drugs are extracted from hair at a significantly lower concentration than in other methods (e.g. urine or oral fluid), underscoring why hair drug screening is the most challenging method to execute.

Confirmation of any positive screening outcome is performed via GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positive results are washed before confirmation as necessary. The entire process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and certification to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can reveal drug consumption for as long as 90 days, compared to urine tests, which offer a shorter detection period.
• Difficult to falsify: It is exceedingly challenging to falsify a hair drug test, leading to more precise results.
• Delivers historical information: It provides a pattern of drug usage over time, not merely recent activity.

Limitations:

• Inability to identify recent consumption: Drugs become noticeable in hair approximately 5-7 days following intake.
• Expense: Hair drug tests typically incur higher costs than other drug testing methodologies.
• Result variation: Elements such as hair color and personal differences in hair growth can influence the levels of drug metabolites in hair.

Note: While frequently termed "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp
