Hair Follicle Drug Testing - Selinsgrove, PA

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol use. It captures a long-term record of substance use by embedding biomarkers within the strands of hair as they grow. When hair is sampled close to the scalp, it can reveal a history of alcohol and drug use spanning up to roughly three months. Collecting hair is straightforward, challenging to tamper with, and easy to transport.

A sample measuring 1.5 inches and consisting of about 200 hairs (roughly the size of a #2 pencil) taken nearest to the scalp yields 100mg of hair, which is optimal for analysis and verification. For EtG, additional tests, or those that exceed 10 panels, a sample size of 150mg is advised. We suggest using a jeweler's scale to weigh the hair. If scalp hair cannot be obtained, a similar quantity of body hair can be used. Head hair refers specifically to scalp hair, while body hair encompasses all other types (e.g., facial, axillary).

Process Overview

The laboratory procedure for processing a drug test result involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase, where the sample is integrated into the lab's system. This step ensures the sample is sealed and transported correctly, assigns it a unique LAN (Laboratory Accessioning Number), and completes any extra data entry that may not be provided by an electronic chain of custody system.

Screening entails an initial brief evaluation for substance abuse. Although Screening provides a cost-efficient method to exclude drug use for most samples, any positive result must undergo confirmation to be accepted in court. Samples that yield a presumptively positive screening require further confirmation.

If Screening suggests a sample is positive, additional hair is extracted from the original sample to prepare for the Extraction phase. During this phase, drugs are isolated from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening one of the most complex procedures.

Confirmation for any positive result in Screening is done using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, any samples that show presumptive positives are cleansed as necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair criteria and conforms to ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests that have a briefer detection period.
• Hard to manipulate: Hair drug tests are challenging to deceive, yielding more reliable results.
• Offers a history of use: It can chart a pattern of drug consumption over time, not merely recent use.

Limitations:

• Inability to detect recent usage: It typically takes 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests are often pricier than other drug assessment methods.
• Result variations: Variables such as hair color and individual hair growth differences can influence the concentration of metabolites within hair.

Note: Despite being commonly called "hair follicle tests," the assessment focuses on the hair strand itself rather than the follicle beneath the scalp.
