Hair Follicle Drug Testing - Thomas, PA

What it is, How it works

Hair testing has emerged as an effective means for identifying the use of drugs and alcohol. Hair captures a prolonged history of alcohol and drugs by embedding biomarkers within the structure of the growing hair strand. When taken near the scalp, hair can offer up to about a 3-month detection period for substances like alcohol and other drugs. Hair collection is straightforward, relatively resistant to tampering, and simple to transport.

A segment of 1.5 inches with roughly 200 hair strands (approximately the size of a #2 pencil) near the scalp yields 100mg of hair, the optimum quantity for screening and verification. For EtG, additional tests, or tests exceeding 10 panels, 150mg of the specimen is advised. It is advisable to use a jeweler’s scale for weighing the specimen. In cases where scalp hair is absent, an equivalent volume of body hair can be obtained. When mentioning head hair, it specifically refers to scalp hair. Body hair includes all other hair types such as facial, axillary, etc.

Process Overview

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

Accessioning is the initial stage of handling a sample in a laboratory's framework. This phase verifies the proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and finalizes any extra data entry that an electronic chain of custody system doesn't provide.

Screening performs a prompt initial evaluation for substances of abuse. While Screening offers a cost-efficient approach to eliminate drug use in the majority of samples, any positive findings must be verified for court acceptability. Samples with preliminary positive results during Screening require further confirmation.

If a sample shows a preliminary positive in Screening, additional hair is extracted from the original specimen and prepped for Extraction. During this phase, drugs are isolated from hair at significantly lower concentrations than in alternative methods (e.g., urine or oral fluid), which is why hair drug screening is the most challenging technique to execute.

Confirmation of a positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are initially positive are washed beforehand as required for confirmation. The comprehensive laboratory operation from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the certification to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug consumption for up to 90 days, compared to urine tests, which have a shorter detection timeframe.
• High resistance to tampering: Cheating a hair drug test is highly challenging, enhancing the accuracy of results.
• Provides usage pattern: It can reveal a timeline of drug use over months, rather than just recent usage.

Limitations:

• Inability to detect recent consumption: Drugs require approximately 5-7 days to become detectable in hair.
• Expense: Hair drug tests are typically more costly compared to other testing methods.
• Result variations: Variables like hair color and individual differences in hair growth can impact the presence of drug metabolites in the hair.

Note: Although often termed as "hair follicle tests," the test assesses the hair strand and not the scalp's hair follicle.

Why Hair Follicle Testing Beats Urine Testing
