Hair Follicle Drug Testing - Onawa, IA

What it is, How it works

Hair analysis has gained recognition as a robust approach for identifying substance and alcohol use. By capturing biomarkers within the fibers of the developing hair strand, hair offers an extended timeline of alcohol and drug exposure. When gathered near the scalp, hair can offer up to an approximate three-month detection period for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and convenient for transportation.

A 1.5-inch hair sample comprising roughly 200 strands (resembling the size of a #2 pencil) nearest to the scalp yields 100mg, which is the optimal amount for screening and confirmation. For EtG, additional tests, or panels beyond 10, 150mg is advisable. It is suggested to weigh the sample on a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be collected. When mentioning head hair, it's specifically about scalp hair. Body hair refers to all other types (facial, underarm, etc.).

Process Overview

The laboratory processing of a drug test result involves four core steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning handles the initial integration of a sample into a lab’s records. It ensures the sample was sealed and transported correctly, allocates a random LAN (Laboratory Accessioning Number), and completes any data entry not catered by an electronic chain of custody system.

Screening is a preliminary rapid assessment for drug presence. Although it is a cost-efficient way to dismiss drug use in most samples, a positive screen needs validation to stand in court. Any samples presumed positive in Screening demand a follow-up confirmation.

If a sample shows a presumptive positive in Screening, more hair is extracted from the original sample for the Extraction phase. Here, drugs are isolated from hair at a significantly lower concentration than in other methods (e.g., urine or saliva), making hair drug screening a challenging method to execute.

Confirmation of any positive screen is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before confirmation if necessary. The entire lab process from Accessioning to Confirmation is monitored under the CAP (College of American Pathologists) Hair classification and certification to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, while urine tests have a shorter timeframe.
• Difficult to circumvent: Cheating a hair drug test is highly challenging, thus enhancing result accuracy.
• Offers historical insights: It can shed light on a pattern of drug use over time, not just recent use.

Limitations:

• Cannot track recent use: Drugs take about 5-7 days to become detectable in hair.
• Cost: Hair drug tests are typically pricier compared to other testing approaches.
• Variation in outcomes: Factors like hair color and individual hair growth differences can influence the presence of drug metabolites in the hair.

Note: Although commonly called "hair follicle tests", the test itself examines the hair strand rather than the follicle beneath the scalp
