Hair Follicle Drug Testing - Lexington, NE

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair strands capture and hold biomarkers within their fibers, offering a detailed account of substance use over an extended period. When a sample is taken from near the scalp, it can reveal up to a 3-month window of alcohol and drug use. Hair collection is straightforward, challenging to falsify, and convenient to transport.

An optimal screening and confirmation sample consists of a 1.5-inch length from around 200 hair strands (similar in size to a #2 pencil), providing about 100mg. For additional tests like EtG or over 10 panel tests, it's advisable to collect 150mg of hair. We suggest verifying the weight with a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair can be used. By head hair, we refer specifically to scalp hair, while body hair pertains to all other types (such as facial or axillary hair).

Process Overview

The lab processing of a drug test involves four critical steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of incorporating a sample into a lab's system. It involves checking that the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input not covered by electronic systems.

Screening acts as a preliminary examination for drugs of abuse. Although it's cost-effective for excluding drug usage in most samples, a positive screen requires confirmation to be valid in legal contexts. Presumptive positives in Screening must undergo secondary confirmation.

Should a sample return a presumptive positive result in Screening, additional hair is taken from it and prepared for Extraction. During Extraction, drugs are isolated from hair at concentrations much lower than those in other methods (like urine or oral fluid), highlighting the complexity of hair drug testing methodology.

Confirmation for any positive results from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positives are prepped with necessary washing. The complete laboratory procedure from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage up to 90 days prior, unlike urine tests which have a shorter detection timeframe.
• High difficulty to manipulate: Tampering with a hair drug test is quite challenging, ensuring more reliable results.
• Insightful historical overview: It provides a timeline of drug usage over time, beyond just recent usage.

Limitations:

• Initial detection delay: Drugs become detectable in hair after roughly 5-7 days.
• Expense: Hair drug tests typically cost more than alternative testing methods.
• Result variability: Variables like hair color and differences in hair growth can influence metabolite concentrations in hair.

Note: The term "hair follicle tests" is commonly used, but the analysis actually involves the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Lexington, NE, hair follicle testing outperforms the traditional urine test, offering significant advantages. Hair testing's extended detection period provides a record of substance use over months, unlike urine tests which detect more recent use.
