Hair Follicle Drug Testing - Lake Lure, NC

What it is, How it works

Hair examinations have increasingly been recognized as an effective method for identifying drug and alcohol consumption. The fibers in growing hair strands trap biomarkers, offering a retrospective view of alcohol and drug usage. When collected from the scalp, hair samples can detect substances over approximately a three-month period. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

To obtain an ideal specimen for screening and confirmation, a 1.5-inch segment of roughly 200 hair strands (akin to a #2 pencil) taken from the scalp provides 100mg, which is ideal. For EtG, supplementary tests, and/or tests exceeding 10 panels, a 150mg sample is advisable. It's suggested to weigh the hair using a jeweler's scale. Should scalp hair be unavailable, collecting an equivalent quantity of body hair is acceptable. The term head hair denotes scalp hair alone, whereas body hair pertains to all other types (such as facial, axillary, etc.).

Process Overview

The laboratory processing of drug test samples involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the preliminary stage of entering a sample into the lab's system. This step ensures the sample was appropriately sealed and transported, allocates a random LAN (Laboratory Accessioning Number), and finalizes any extra data entry not covered by an electronic chain of custody system.

Screening performs an initial rapid assessment for substances of abuse. While it serves as an economical method to eliminate drug usage in most samples, a confirmed positive result is required for legal admissibility. Samples indicating presumptive positivity during Screening mandate additional confirmation.

For samples flagged as presumptively positive during the Screening phase, more hair from the initial sample undergoes preparation for Extraction. Here, drugs are extracted from hair at lower concentrations than other methods (such as urine or oral fluid), making hair drug screening particularly challenging.

A positive result from Screening is confirmed through processes like GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumptively positive undergo washing before confirmation as necessary. The comprehensive laboratory procedure, right from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair tests can reveal drug usage up to 90 days, unlike urine tests, which have a shorter detection period.
• High tamper resistance: Cheating a hair drug test is notably difficult, enhancing result reliability.
• Offers chronological data: Hair tests can show a pattern of drug consumption over time, not just recent usage.

Limitations:

• Incapable of detecting recent usage: Approximately 5-7 days are necessary for drugs to become detectable in hair.
• Expense: Hair tests generally cost more than other drug testing techniques.
• Result variability: Factors like hair color and personal differences in hair growth can influence drug metabolite concentrations within hair.

Note: Commonly labeled as "hair follicle tests," these assessments actually analyze the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Lake Lure, NC, hair follicle drug tests demonstrate clear advantages over traditional urine tests. One reason is their ability to detect drug residue within the hair shaft, which provides a more permanent record of past usage.

Urine tests, while common, have limitations in their detection window. Hair tests, on the other hand, provide a broader view of an individual's drug history, making them superior in offering a reliable perspective of substance use.

Extended Detection Window

Employers in Lake Lure, NC, benefit from hair follicle testing's extended detection window. Unlike other testing methods, hair analysis can reveal drug use history going back as far as 90 days.

This broader detection period enables employers to obtain a complete view of an individual's substance use, which is crucial for making informed and confident hiring decisions.

Tamper-Resistant Testing Method

Hair follicle drug tests are renowned for their tamper-resistant nature, especially in Lake Lure, NC. This method significantly reduces the possibility of sample adulteration, unlike urinary tests, which can be more easily compromised.

With hair testing, the integrity of the results is maintained, ensuring that the outcome is both reliable and definitive, which is invaluable for both employers and testing agencies.

Convenient Nationwide Locations

Accredited Drug Testing offers convenient testing locations nationwide, including in Lake Lure, NC. This ensures that accessing testing services is quick, easy, and hassle-free.

Both local and nationwide availability of testing centers means that individuals and employers have a straightforward path to obtaining the tests they require efficiently.

Simple, Confidential Process
