Hair Follicle Drug Testing - Casa, AR

What it is, How it works

Hair testing has emerged as an effective method for identifying drug and alcohol use. Hair offers a long-lasting record of alcohol and drugs due to the capture of biomarkers within the fibers of the growing hair strand. When acquired near the scalp, hair can present a detection range of up to around 3 months for alcohol and drugs. Hair is straightforward to collect, relatively hard to tamper with, and convenient to transport.

A 1.5-inch piece of around 200 hair strands (roughly the width of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, additional panels, and/or tests exceeding 10 panels, 150mg of the sample is advised. It's suggested to weigh the sample using a jeweler’s scale. If there isn’t scalp hair, a similar amount of body hair can be gathered. When referencing head hair, we mean scalp hair exclusively. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The four primary stages in laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into a laboratory’s system. This process includes verifying that the sample was sealed and transported properly, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not provided by an electronic chain of custody system.

Screening is a preliminary rapid check for substances of abuse. While Screening is a cost-effective method to exclude drug use in the majority of samples, a positive result needs to be confirmed for admissibility in court. Any samples presumptively positive in Screening need secondary confirmation.

If a sample is indicated as positive in the Screening phase, more hair is extracted from the initial sample and prepared for Extraction. In this phase, drugs are extracted from hair at a much lower concentration than in other methodologies (e.g., urine or oral fluid), which makes hair drug screening the most challenging methodology to perform.

Confirmation of any positive screening result is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation, as necessary. The entire lab workflow from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair certification and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can discern drug use for as long as 90 days, in comparison with urine tests, which have a shorter detection range.
• Cheat-proof: It is exceptionally challenging to cheat a hair drug test, enhancing the accuracy of results.
• Displays historical usage: It provides a timeline of drug use over a duration, rather than just recent use.

Limitations:

• Recent use undetectable: It requires approximately 5-7 days for drugs to manifest in hair.
• Expense: Hair drug tests tend to be pricier than other drug testing methods.
• Result variability: Variables such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Though commonly referred to as "hair follicle tests", the analysis is conducted on the hair strand, not on the follicle beneath the scalp.
