Hair Follicle Drug Testing - River Sioux, IA

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, providing an extended timeline of substance use. When taken from near the scalp, hair offers a detection period of up to around three months for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and easy to transport.

A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil) closest to the scalp yields 100mg of hair, considered the optimal sample size for testing and confirmation. For EtG, additional tests, and/or panels beyond 10, a sample weight of 150mg is advised. It is suggested to measure the specimen with a jeweler's scale. Should scalp hair be unavailable, an equivalent quantity of body hair may be used. "Head hair" refers specifically to scalp hair, whereas "body hair" denotes all other types (facial, axillary, etc.).

Process Overview

The key stages in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, the sample undergoes initial processing into the lab's system, ensuring it was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing other necessary data entry beyond what an electronic chain of custody provides.

In the Screening stage, a quick initial test for drug abuse is conducted. While Screening is a cost-effective method to eliminate drug usage in most samples, a positive result must be confirmed for court acceptability. Samples with presumptive positive results in Screening require further confirmation.

Presumptive positive samples in the Screening phase lead to additional hair being extracted from the original sample for the Extraction stage. During Extraction, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.

Confirmation of positive Screening results is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are washed before confirmation if required. The comprehensive lab process, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug testing can identify drug use up to 90 days, compared to urine tests which offer a shorter detection period.
• Challenges in cheating: It's notably hard to manipulate a hair drug test, enhancing the precision of results.
• Historical data provision: It reveals a drug use pattern over time, not merely recent consumption.

Limitations:

• Limited detection of recent use: Drugs become detectable in hair only after approximately 5-7 days.
• Cost considerations: Hair drug tests tend to be pricier than alternative testing methods.
• Result variability: Elements like hair color and individual hair growth differences can influence drug metabolite concentration in hair samples.

Note: Commonly labeled as "hair follicle tests", these tests analyze the hair strand, not the follicle beneath the scalp.
