Hair Follicle Drug Testing - Caln, PA

What it is, How it works

Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. The fibers within a growing hair strand capture biomarkers, providing a historical record of alcohol and other substances. Hair taken close to the scalp offers around a three-month detection timeframe for alcohol and drugs. It's easily collected, hard to tamper with, and convenient to transport.

A 1.5-inch section of roughly 200 hair strands (comparable to a #2 pencil in thickness) nearest the scalp yields 100 mg of hair, which is perfect for both screening and confirmation tests. For EtG additions, or tests exceeding 10 panels, a 150 mg specimen is advised. We suggest using a jeweler’s scale to weigh the specimen. In the absence of scalp hair, an equivalent amount of body hair may be used. "Head hair" refers solely to scalp hair. "Body hair" encompasses all other hair types, including facial, axillary, etc.

Process Overview

The drug testing process at a laboratory involves four essential steps: Accessioning, Screening, Extraction, and Confirmation.

The initial phase, Accessioning, integrates a sample into the lab system. This entails confirming that the sample was secured and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any outstanding data entries not captured by an electronic chain of custody system.

During the Screening phase, there's a preliminary rapid screening for drugs. Although Screening is economical for ruling out drug use in most samples, a positive result necessitates validation for legal admissibility. Any samples with a presumptively positive result in Screening must undergo further confirmation.

If Screening suggests a positive result, additional hair is taken from the original sample and readied for Extraction. This phase involves isolating drugs from hair at a much lower concentration than seen in other methods (such as urine or oral fluids), making hair drug testing a complex methodology.

Confirmation of any positive findings from the screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples with presumptive positives are cleansed as required. The complete process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and accreditation per ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests with a shorter detection span.
• Hard to manipulate: Hair drug tests are challenging to cheat, resulting in more reliable outcomes.
• Shows usage patterns: They reveal a timeline of drug consumption over time, beyond just recent use.

Limitations:

• Inability to detect recent usage: Drugs become identifiable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug testing is usually costlier than alternative testing methods.
• Result variability: Factors like hair color and individual hair growth differences might influence drug metabolite levels in hair.

Note: Commonly termed "hair follicle tests," the test actually examines the hair strand, not the follicle beneath the scalp.
