Hair Follicle Drug Testing - Rock Island, OK

What it is, How it works

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. The hair captures a chronological record of substance intake by embedding chemical markers within its growing strands. When collected near the scalp, hair can offer up to an approximate 3-month detection span for alcohol and other substances. It's straightforward to collect, relatively challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches of approximately 200 hair strands (about the size of a #2 pencil) closest to the scalp yields 100mg, which is the preferred sample size for screening and confirmation. For EtG, additional tests, and/or screenings beyond 10 panels, a 150mg specimen is advised. Utilize a jeweler’s scale for weighing the sample. If scalp hair isn't available, an equivalent amount from the body can be used. By head hair, we mean scalp hair strictly. Body hair covers all other types, such as facial, axillary, etc.

Process Overview

The laboratory processing of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary handling of a sample into a lab's system. This step includes confirming that the sample was sealed and dispatched correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data entry not supplied by an electronic chain of custody system.

Screening involves a preliminary swift check for drugs of abuse. Though Screening is a cost-efficient strategy for excluding drug usage in most samples, a positive screen mandates confirmation for legal validity. Any samples with presumptive positivity in Screening necessitate an additional confirmation.

Should a sample exhibit presumptive positivity during the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. During this stage, drugs are drawn from hair at substantially lower concentrations than other methods (e.g., urine or oral fluid), rendering hair drug screening the most intricate method to execute.

Confirmation of any positive screen result is conducted through GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as required. The end-to-end laboratory process from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair designation along with ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can track substance use for up to 90 days, in contrast to urine tests with a more limited detection span.
• Challenging to falsify: Falsifying a hair drug test is notably challenging, enhancing the reliability of results.
• Reveals historical use: It can offer an account of drug consumption over time, not just current use.

Limitations:

• Inability to detect recent use: Drugs require about 5-7 days to become detectable in hair.
• Expense: Hair drug tests tend to be pricier compared to other testing techniques.
• Result variability: Factors such as hair pigmentation and individual hair growth differences can impact drug metabolite concentration in the hair.

Note: Although commonly termed as "hair follicle tests", the assessment analyzes the hair strand instead of the follicle beneath the scalp
