Hair Follicle Drug Testing - Loretto, PA

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol usage. Hair can reveal a prolonged history of alcohol and drug presence by capturing biomarkers within its fibers as it grows. When sampled near the scalp, hair offers about a 3-month detection period for substances. Hair collection is straightforward, relatively tamper-resistant, and easy to transport.

A sample size of 1.5 inches, consisting of approximately 200 hair strands (comparable to a #2 pencil's width) nearest the scalp, yields 100mg of hair, ideal for testing and validation. For EtG, additional testing, or panels exceeding 10, 150mg of the sample is advised. A jeweler's scale is recommended to measure the specimen. If scalp hair is unavailable, a similar quantity of body hair may be used. References to head hair imply scalp hair only, while body hair includes all other types (such as facial, underarm, etc.).

Process Overview

There are four primary phases in the lab processing of drug tests: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where samples are integrated into the lab's system. This process confirms the appropriate sealing and shipping of samples, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional data input absent from electronic custody chains.

Screening provides a preliminary assessment for substance abuse. It's an affordable approach to eliminate drug usage in most samples, but any positive findings must be corroborated for legal validation. Presumptive positives in Screening require further confirmation.

Presumptive positives in the Screening phase lead to additional hair extraction for further testing. Here, the concentration of drugs is extracted from hair, which is more challenging than methods like urine or saliva testing, making hair drug analysis particularly complex.

Confirmation of positive results is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are washed before confirmation, as required. The complete process from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 certification.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, unlike the shorter periods of urine tests.
• Minimal opportunity for tampering: Cheating a hair drug test is extremely difficult, enhancing result accuracy.
• Evidence of historical use: Hair tests reflect a drug use pattern over time, not solely recent usage.

Limitations:

• Not suitable for recent use: Drugs require about 5-7 days to become detectable in hair.
• Expense: Hair drug tests generally incur higher costs compared to other methods.
• Result variability: Hair color and individual growth differences can impact drug metabolite levels in hair.

Note: Often termed "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

The preference for hair follicle over urine testing is evident in Loretto, PA due to its superior detection capabilities. Hair follicle tests offer a broader detection window, usually up to 90 days, versus the shorter span provided by urine tests. This extended period enhances accuracy and reliability, crucial for employers and institutions needing dependable data for drug use evaluation.
