Hair Follicle Drug Testing - Dixie, WV

What it is, How it works

Hair testing is recognized as an effective instrument in identifying the use of drugs and alcohol. It offers a prolonged history of substance use by trapping biomarkers within the fibers of growing hair strands. With hair collected near the scalp, it can offer up to a three-month detection timeframe for substances. Hair is straightforward to collect, resistant to tampering, and convenient to transport.

A sample of 1.5 inches, consisting of about 200 hair strands (similar in size to a #2 pencil) located closest to the scalp, will yield 100mg of hair, which is the preferred sample amount for initial testing and validation. For EtG, extended tests, or panels exceeding 10, 150mg of the sample is advised. Utilizing a jeweler’s scale to weigh the sample is recommended. If scalp hair is unavailable, a similar quantity of body hair can be gathered. When discussing head hair, only scalp hair is included. Body hair encompasses other hair types (such as facial or axillary hair).

Process Overview

The four key phases in processing a drug test result in the laboratory are Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, the sample undergoes initial processing into the laboratory’s database. This process verifies the proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and concludes any essential data entry not rendered by an electronic chain of custody system.

Screening encompasses a preliminary fast check for substances. While it’s a cost-efficient method to eliminate drug use in most samples, a positive screening must be confirmed to be legally acceptable. Any samples found presumptively positive during Screening necessitate further confirmation.

When a sample shows a presumptive positive result in Screening, additional hair is extracted from the original sample for the Extraction phase. Here, substances are isolated from the hair at significantly lower concentrations than in other techniques (such as urine or oral fluid), which is why hair drug screening is one of the most challenging methodologies to conduct.

Confirmation of positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if necessary. The full laboratory process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Prolonged detection span: Hair drug tests identify drug use up to 90 days, unlike urine tests, which have briefer detection windows.
• Difficult to manipulate: Hair drug tests are difficult to falsify, rendering results more reliable.
• Provides historical insight: It reveals a drug use pattern over time, rather than just recent usage.

Limitations:

• Cannot detect recent usage: It takes around 5-7 days for drugs to manifest in the hair.
• Expense: Hair drug tests generally cost more than other testing methods.
• Result variances: Elements like hair color and individual differences in hair growth can influence drug metabolite concentrations in the hair.

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