Hair Follicle Drug Testing - Mount Vernon, MO

What it is, How it works

Hair testing is now recognized as a strong method for identifying drug and alcohol use. Hair offers an extended record of alcohol and drug usage by embedding biomarkers in the fibers of the growing hair strand. When taken near the scalp, hair can reveal drug and alcohol use for roughly a 3-month period. Collecting hair is straightforward, challenging to tamper with, and easy to transport.

A 1.5-inch sample comprising about 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp is required to yield 100mg of hair, which is the ideal quantity for analysis and verification. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale for measurement. If scalp hair isn't available, a similar quantity of body hair can be used. When we mention head hair, we refer exclusively to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning involves the sample's initial introduction into a lab's system. This stage checks the sample's integrity in terms of sealing and shipping, assigns a LAN (Laboratory Accessioning Number), and performs any additional data entry absent from an electronic chain of custody system.

Screening entails a rapid preliminary assessment for drug presence. While screening is a cost-effective method to rule out drug usage in most samples, a positive result necessitates confirmation for legal admissibility. Any Screening samples with a presumptive positive need further confirmation.

Should a sample yield a presumptive positive in Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are removed from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening one of the most complex methodologies to apply.

Confirmation of any positive result in screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumed positive are washed before confirmation if needed. The end-to-end laboratory procedure from Accessioning to Confirmation is reviewed under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests have the ability to detect drug use up to 90 days, unlike urine tests which offer fewer days.
• Hard to falsify: Cheating a hair drug test is notably difficult, ensuring more reliable outcomes.
• Reveals usage patterns: It documents a drug use pattern over time, not just recent consumption.

Limitations:

• Unable to detect immediate use: It generally takes around 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests tend to be pricier than other testing approaches.
• Result variability: Elements like hair color and personal differences in hair growth can influence drug metabolite levels in hair.

Note: Though often called "hair follicle tests", the actual analysis is conducted on the hair strand, not the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing to traditional urine testing in Mount Vernon, MO, the former stands out due to its superior detection accuracy. While urine tests account for recent use, hair tests offer insight into longer-term patterns, aiding in comprehensive assessments and policy compliance.
