Hair Follicle Drug Testing - Newhope, AR

What it is, How it works

Hair testing is recognized as a potent method for uncovering drug and alcohol consumption. It offers a prolonged history of substance use, as the hair fibers capture biomarkers during hair growth. When sampling near the scalp, hair can present a detection window of up to around three months for alcohol and drugs. It's straightforward to collect, relatively resistant to tampering, and simple to transport.

An optimal sample comprises a 1.5-inch segment of roughly 200 hair strands (akin to the width of a #2 pencil) nearest to the scalp, yielding around 100mg of hair suitable for screening and verification. For EtG, additional tests, or those surpassing 10 panels, a quantity of 150mg is advisable. It's suggested to measure the specimen using a jeweler’s scale. In the absence of scalp hair, an equivalent amount of body hair may be procured. When 'head hair' is mentioned, it pertains solely to scalp hair, whereas 'body hair' includes all other varieties (facial, axillary, etc.).

Process Overview

The drug test result laboratory process comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial sample processing into a lab’s system. It involves verifying the proper sealing and shipment of the sample, allocating a random LAN (Laboratory Accessioning Number), and completing supplementary data entry not covered by an electronic custody chain system.

Screening performs a preliminary rapid assessment for substances of abuse. Although Screening cost-effectively excludes drug usage from most samples, a positive screen mandates confirmation for courtroom admissibility. Any samples with presumptive positives in Screening necessitate additional confirmation.

If a sample tests presumptively positive during Screening, more hair is taken from the original sample for Extraction. In this phase, substances are extracted from hair in lower concentrations than other techniques (e.g., urine or oral fluid), making hair drug screening the most challenging to execute.

Confirmation of any positive screen results is achieved through GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positives undergo cleansing prior to confirmation as required. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and meets ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage up to 90 days, whereas urine tests have a shorter detection scope.
• Test tampering is challenging: Tampering with a hair drug test is arduous, thus enhancing result precision.
• Supplies historical insight: It outlines substance use trends over time, not merely recent usage.

Limitations:

• Unable to detect recent intake: It typically requires about 5-7 days for substances to manifest in hair.
• Expense: Hair drug tests tend to be costlier than other methodologies.
• Result variability: Factors such as hair coloration and personal hair growth differences can influence drug metabolite levels within the hair.

Note: Though frequently termed "hair follicle tests", the test actually examines the hair strand and not the follicle beneath the scalp.
