Hair Follicle Drug Testing - Greencastle, PA

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol use. Hair captures a long-term record of these substances by embedding biomarkers within the strands of hair as they grow. When collected close to the scalp, hair offers about a 3-month detection period for alcohol and drug use. Hair is easy to collect, challenging to tamper with, and straightforward to transport.

A 1.5-inch segment of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, the optimal sample size for screening and verification. For EtG, add-on tests, and/or tests over 10 panels, 150mg of the sample is suggested. It is advisable to measure the sample weight using a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair can be used. The term head hair pertains specifically to scalp hair. Body hair encompasses all other types of hair (e.g., facial, underarm, etc.).

Process Overview

The key stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample into a lab’s system. This process includes confirming the sample's secure sealing and shipping, generating a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent in an electronic chain of custody system.

Screening involves a preliminary check for substance use. While it provides a cost-efficient method for dismissing drug use in the majority of samples, any positive screening result must be validated to be credible for legal purposes. Samples that test presumptively positive in Screening require further confirmation.

When a sample tests presumptively positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than other methods (like urine or saliva), which is why hair drug testing is the most challenging method to execute.

Positive results from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples presumptively testing positive are cleansed prior to confirmation as necessary. The full lab protocol from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and follows ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, contrasting with urine tests, which have a shorter detection span.
• Hard to tamper with: Cheating a hair drug test is quite difficult, ensuring more reliable results.
• Tracks historical data: It delivers a timeline of drug use over a longer stretch, not just immediate use.

Limitations:

• Cannot determine recent usage: Drugs generally take 5-7 days to be traceable in hair.
• Expense: Hair drug tests tend to be costlier than alternative drug testing approaches.
• Result variations: Variables like hair color and personal differences in hair growth can influence the level of drug metabolites in the hair.

Note: Although frequently called "hair follicle tests", these tests examine the hair shaft, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Greencastle, PA showcases clear advantages over conventional urine tests.
