Hair Follicle Drug Testing - Wylandville, PA

What it is, How it works

Hair analysis is increasingly recognized as a potent method for identifying drug and alcohol consumption. Hair captures a historical record of drug and alcohol intake by embedding biomarkers within the fibers as the hair grows. Samples taken near the scalp can offer a detection period of up to three months for both alcohol and drugs. The collection process is straightforward, making it hard to tamper with and easy to transport.

A 1.5-inch portion from about 200 hair strands (roughly equivalent to the size of a #2 pencil) near the scalp yields 100mg of hair, which is the ideal quantity for both screening and confirmation. For EtG, additional tests, or tests beyond 10 panels, a sample size of 150mg is preferable. We suggest measuring the sample using a jeweler's scale. If scalp hair is missing, a similar quantity of body hair may be used. By head hair, we mean scalp hair only, while body hair includes all other types such as facial or axillary hair.

Process Overview

The primary steps involved in processing a drug test result in the laboratory are Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the initial incorporation of a sample into the lab's system occurs. This step includes ensuring that the sample was appropriately sealed and transported, assigning a unique Laboratory Accessioning Number (LAN), and completing any data input absent from an electronic chain of custody system.

Screening is an initial quick test for drugs of abuse. Although screening is an economical method to dismiss drug usage in most samples, a positive outcome necessitates confirmation to be used in legal proceedings. Samples that presumptively test positive during Screening require further validation.

If a sample exhibits a presumptive positive during Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are extracted from hair at a much lower concentration than in other methods like urine or saliva, making hair drug testing a more challenging technique to execute.

Positive results from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo washing as necessary. The full laboratory process from Accessioning through Confirmation is reviewed under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests, which have a narrower detection scope.
• Hard to manipulate: Cheating on a hair drug test is quite challenging, therefore enhancing the accuracy of the results.
• Offers use patterns: It can indicate a timeline of drug consumption over time, rather than just recent usage.

Limitations:

• Inability to detect recent consumption: Detecting drugs in hair requires about 5–7 days after use.
• Expense: Hair drug tests tend to be pricier than alternative drug testing methods.
• Fluctuations in results: Aspects like hair color and personal variations in hair growth can influence metabolite concentration levels.

Note: Despite being referred to as "hair follicle tests", the examination involves the hair strand itself, not the follicle beneath the scalp.
