Hair Follicle Drug Testing - Waxhaw, NC

What it is, How it works

Hair testing is increasingly recognized as an effective method for detecting drug and alcohol consumption. Hair retains a long-term record of alcohol and drug use by embedding biomarkers within its growing strands. When taken near the scalp, hair can show a detection period of up to about three months for alcohol and drugs. Hair collection is easy, hard to tamper with, and simple to transport.

A sample of 1.5 inches consisting of roughly 200 strands of hair (approximately as thick as a #2 pencil) closest to the scalp will provide 100mg of hair, which is ideal for screening and confirmation. For EtG, additional tests, and/or tests beyond 10 panels, 150mg of the sample is advised. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair is not available, a similar amount of body hair can be used. "Head hair" specifically refers to hair from the scalp. "Body hair" includes all other hair types like facial and axillary hair.

Process Overview

The laboratory procedure to process drug test results involves four main steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step where a sample is input into a lab's system. This step confirms whether the sample was sealed and sent correctly, assigns a random LAN (Laboratory Accessioning Number), and logs any required data not covered by an electronic chain of custody system.

Screening provides an initial check for drug misuse. Although Screening is economical for excluding drug usage in most samples, a positive result must undergo confirmation for legal admissibility. Any samples that test presumptively positive in Screening need secondary confirmation.

Should a sample test presumptively positive during Screening, more hair is extracted from the initial sample to prepare for Extraction. In this phase, drugs are removed from hair at much lower concentrations than other methods (like urine or oral fluid tests), making hair drug screening particularly challenging to execute.

Confirming any positive screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptively positive samples are cleansed as needed. The entire lab procedure from Accessioning to Confirmation is scrutinized in accordance with both CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Hard to manipulate: Cheating a hair drug test is very challenging, making the results more reliable.
• Shows historical data: It can depict a pattern of drug consumption over time, not just recent use.

Limitations:

• Cannot detect recent consumption: Drugs generally become detectable in hair around 5-7 days after use.
• Expense: Hair drug tests tend to be more costly than other drug testing techniques.
• Result variability: Elements like hair color and individual hair growth variations can impact the level of drug metabolites in the hair.

Note: While commonly called "hair follicle tests", the test examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

For individuals and enterprises in Waxhaw, NC, hair follicle testing offers unmatched advantages over urine tests.
