Hair Follicle Drug Testing - Harris Hill, NY

What it is, How it works

Hair testing is increasingly recognized as a formidable method for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, offering an extended timeline for detecting substances. When sourced near the scalp, hair samples allow for up to a three-month detection period for drugs and alcohol. Furthermore, hair collection is straightforward, resistant to tampering, and easy to transport.

Collecting a 1.5-inch segment of around 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp amounts to 100mg, the optimal sample amount for analysis and verification. For EtG, additional tests, or panels exceeding ten, 150mg is suggested. Utilizing a jeweler’s scale for specimen weight is advised. If scalp hair is unavailable, an equivalent quantity of body hair may be substituted. "Head hair" pertains solely to scalp hair, while "body hair" encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result consists of four key stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially processed into the laboratory's system. This process involves ensuring the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry that isn’t covered by an electronic chain of custody system.

Screening provides a preliminary assessment for drug abuse. Although Screening is a cost-efficient means to rule out drug use in most samples, confirmation of a positive result is required for legal acceptability. Samples yielding presumptive positive results in Screening need a subsequent confirmation.

Should a sample yield a presumptive positive in Screening, further hair is extracted from the initial sample for Extraction. During Extraction, drugs are extracted from hair at concentrations notably lower than those in alternate methods (e.g., urine or oral fluid), hence why hair drug testing is a complex method to execute.

Positive results in Screening undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptive positive are washed before confirmation as deemed necessary. The whole process from Accessioning to Confirmation is conducted in accordance with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can reveal drug usage up to 90 days, which is considerably longer than the detection window of urine tests.
• Resistance to tampering: Hair drug tests are hard to manipulate, ensuring more reliable results.
• Historic data provision: Hair tests can outline a timeline of drug use, unlike tests that only detect recent usage.

Limitations:

• Inability to detect recent usage: Approximately 5-7 days are required for drugs to become detectable in hair.
• Higher cost: Hair drug tests usually carry a higher price tag compared to other drug testing techniques.
• Result variability: Factors like hair color and personal differences in hair growth can influence drug metabolite levels in hair.

Note: Although commonly termed "hair follicle tests," the analysis focuses on the hair strand itself, excluding the follicle located under the skin.
