Hair Follicle Drug Testing - Winterstown, PA

What it is, How it works

The practice of hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair can offer an extended timeline of substance use by embedding biomarkers within its fibers as it grows. When hair is collected near the scalp, it can offer a detection period of up to roughly three months for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A hair sample measuring 1.5 inches with approximately 200 strands (comparable to the thickness of a #2 pencil) taken closely from the scalp should weigh around 100mg—a perfect amount for screening and validation. For EtG tests, add-ons, or more extensive tests exceeding 10 panels, a 150mg sample is advisable. We suggest using a jeweler’s scale for weighing. In cases where scalp hair is not available, an equivalent quantity of body hair can be used. When discussing head hair, we specifically refer to scalp hair. Body hair encompasses all other forms of hair (such as facial hair, axillary hair, etc.).

Process Overview

The drug testing in the laboratory is conducted in four crucial stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary phase where a sample is integrated into the laboratory’s workflow. This phase involves confirming that the sample was properly sealed and transported, generating a random Laboratory Accessioning Number (LAN), and performing any pending data entry not managed by an electronic custody chain system.

Screening is an initial swift evaluation for substance misuse. Although Screening is a cost-effective approach to exclude drug usage in most cases, a positive outcome from screening must be validated for legal acceptability. Any sample indicating a potential positive in Screening necessitates further confirmation.

Once a sample shows a presumptive positive during the Screening, extra hair is extracted from the initial sample for the Extraction stage. Here, drugs are removed from hair at significantly lower concentrations compared to other methods (such as urine or saliva), making hair drug testing the most challenging method to execute.

Verification for any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleaned before final confirmation as necessary. The complete process, from Accessioning to Confirmation, is evaluated under the guidelines of the College of American Pathologists (CAP) Hair status and compliant with ISO/IEC 17025 certification.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug usage for up to 90 days, contrasting with urine testing’s shorter detection span.
• Hard to manipulate: Attempting to deceive a hair drug test is extremely tough, yielding more precise results.
• Historical insight: It provides insight into drug usage patterns over an extended period, rather than just recent usage.

Limitations:

• Lacks early detection: Drugs typically become detectable in hair in about 5-7 days.
• Expense: Hair drug tests often incur higher costs compared to alternative methods.
• Result variability: Factors like hair color and individual differences in hair growth can impact drug metabolite concentrations in hair.

Note: Although commonly termed "hair follicle tests", the analysis is conducted on the hair strand itself, not the follicle located beneath the scalp.
