Hair Follicle Drug Testing - Holtwood, PA

What it is, How it works

Hair testing has emerged as an influential resource for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug use by embedding biomarkers within the fibers of the maturing hair strand. When sourced near the scalp, hair can offer an estimated 3-month detection span for alcohol and drug presence. Hair is straightforward to collect, challenging to tamper with, and easy to transport.

A sample of 1.5 inches containing approximately 200 hair strands (similar to the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample for screening and validation. For EtG, additional testing, and/or assessments beyond 10 panels, a 150mg specimen is suggested. Utilizing a jeweler’s scale for weighing the specimen is advisable. If scalp hair is not accessible, a comparable quantity of body hair may be used. Head hair specifically refers to scalp hair only, whereas body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory procedures for processing a drug test result consist of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial integration of a sample into a laboratory's framework. This process involves affirming that the sample was secured and forwarded properly, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry that an electronic chain of custody system does not supply.

Screening involves a preliminary rapid assessment for drug abuse. Although Screening is a budget-friendly method to exclude drug usage for most samples, a positive result from screening must be substantiated for court acceptability. Samples exhibiting positive indications in Screening require an auxiliary confirmation.

Should a sample show presumptively positive results at the Screening stage, additional hair is extracted from the original specimen for the Extraction process. During this phase, drugs are extracted from hair at notably lower concentrations than other techniques (such as urine or oral fluid), making hair drug screening the most challenging technique to conduct.

Confirmation of any positive screening outcomes is performed utilizing GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleansed before confirmation as necessary. The entire laboratory procedure from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug analyses can identify drug use for up to 90 days, while urine tests offer a shorter detection duration.
• Challenging to manipulate: Cheating a hair drug test is considerably difficult, ensuring more precise results.
• Historical data provision: It yields a usage pattern of drugs over time, rather than just recent usage.

Limitations:

• Inability to detect recent use: It takes around 5-7 days for drugs to be noticeable in hair.
• Expense: Hair drug tests are typically costlier than other drug detection methods.
• Result variation: Factors like hair color and individual discrepancies in hair growth can influence the drug metabolite concentration within the hair.

Note: While commonly termed as "hair follicle tests", the analysis focuses on the hair strand and not the sub-scalp hair follicle.
