Hair Follicle Drug Testing - Washington Park, NC

What it is, How it works

Hair testing is widely regarded as an effective means for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and various drugs by embedding biomarkers within the strands of emerging hair. When taken near the scalp, hair is capable of offering nearly a 3-month detection timeframe for alcohol and additional substances. Hair is easy to gather, relatively challenging to tamper with, and straightforward to transport.

A sample measuring 1.5 inches containing roughly 200 hair strands (resembling the diameter of a #2 pencil) nearest to the scalp will yield 100mg, the optimal amount for both screening and verification. For EtG, supplemental tests, and/or examinations beyond 10 panels, 150mg of the sample is advised. Utilizing a jeweler’s scale to weigh the specimen is suggested. If scalp hair is lacking, an equivalent volume of body hair may be utilized. When mentioning head hair, it specifically refers to scalp hair. Body hair denotes all other types of hair (facial, axillary, etc.).

Process Overview

The primary procedures encompassed in the laboratory processing for drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises the initial handling of a sample into the laboratory’s framework. This step ensures the sample was suitably sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and concludes any extra data entry absent from an electronic chain of custody system.

Screening constitutes an initial swift evaluation for drugs of abuse. Although Screening is a cost-efficient method to exclude drug involvement in the majority of samples, a positive screen must undergo confirmation to be valid in legal proceedings. Any samples preliminarily identified as positive in Screening mandate a follow-up confirmation.

Should a sample be preliminarily positive during the Screening phase, additional hair is extracted from the initial specimen for Extraction. During this phase, drugs are retrieved from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), highlighting why hair drug screening is the most complex method to perform.

Verification of any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples preliminarily deemed positive are cleansed before confirmation if necessary. The comprehensive lab procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair specification and adheres to ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Extended detection range: Hair drug tests can identify drug usage for as long as 90 days, unlike urine tests, which have a briefer detection period.
• Difficult to evade: Cheating a hair drug test is exceptionally challenging, ensuring more accurate results.
• Supplies historical insight: It reveals a pattern of drug use across time, not merely recent consumption.

Constraints:

• Incapable of identifying recent consumption: It requires approximately 5-7 days for substances to become traceable in hair.
• Expense: Generally, hair drug tests carry a higher cost compared to other drug testing approaches.
• Result variations: Attributes like hair color and personal differences in hair growth can influence drug metabolite concentration in hair.

Note: Though frequently termed "hair follicle tests", the examination targets the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing the benefits of hair follicle and urine testing in Washington Park, NC, the former stands out significantly.
Hair testing boasts extended detection periods and increased accuracy. Unlike urine tests, hair samples reveal a comprehensive timeline of substance use, free from the influence of short-term abstinence that may affect urine results.

• Employers favor hair testing due to its reliable outcomes.
• Such tests surpass traditional methods in detecting long-term use.

Extended Detection Window

In Washington Park, NC, hair follicle testing offers an extended detection window of up to 90 days. Employers benefit from a thorough insight into an individual's substance use history, allowing for better-informed staffing decisions. This longer detection horizon distinguishes hair testing from shorter-term assessments like urine exams.

• Provides a more complete picture of habitual use.
• This method is preferred for its lengthy detection span.

Tamper-Resistant Testing Method

Hair follicle tests in Washington Park, NC, exemplify a tamper-resistant methodology, greatly minimizing the risk of sample adulteration. The integrity these tests offer is vital to employers and legal systems needing unquestionable results. Hair samples are less susceptible to manipulation compared to liquid-based tests.

• This ensures a trustworthy and reliable outcome.
