Hair Follicle Drug Testing - Pella, IA

What it is, How it works

Hair analysis has become recognized as an impactful method for identifying drug and alcohol consumption. By encasing biomarkers within the fibers of developing hair strands, hair offers an extended overview of drug and alcohol use. When sourced near the scalp, hair can reveal substance usage over an approximate 3-month span. Hair's collection is straightforward, it resists tampering, and is convenient for shipment.

A 1.5-inch segment from roughly 200 hair strands (comparable to the diameter of a #2 pencil) nearest to the scalp yields about 100mg of hair, which is the preferred sample size for analysis and verification. In cases involving EtG, additional assessments, or tests exceeding 10 panels, 150mg of the sample is advised. Using a jeweler's scale to measure the sample is recommended. If head hair is not available, a similar quantity of body hair may be substituted. "Head hair" refers specifically to scalp hair, while "body hair" encompasses all other types (such as facial and axillary hair).

Process Overview

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

Accessioning is the process of entering a specimen into a lab's system. It involves ensuring the sample's proper sealing and shipping, generating a random LAN (Laboratory Accessioning Number), and completing any extra data entries not covered by an electronic chain of custody system.

Screening consists of an initial drug abuse assessment. Although Screening is an economical approach to ruling out drug consumption in the majority of cases, a positive result requires confirmation for court admissibility. Any samples showing a positive indication from Screening need additional verification.

If the Screening suggests a positive result, further hair is extracted from the primary specimen for Extraction. At this stage, drugs are separated from hair at a concentration significantly lower than found in other methodologies (e.g., urine or oral fluid), highlighting why hair drug testing is the most complex methodology.

Confirmation of any positive outcome from Screening is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation, as necessary. The procedure from Accessioning to Confirmation is assessed under the guidelines of both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair testing can identify drug use for up to 90 days, in contrast to urine testing which has a shorter period.
• Resistance to manipulation: The accuracy of hair drug testing is supported by its resistance to tampering.
• Chronological data: It provides insight into drug consumption patterns over time, unlike tests that show only recent use.

Limitations:

• Inability to detect immediate usage: It generally takes 5-7 days before drugs are traceable in hair.
• Expense: Generally, hair testing incurs higher costs than other drug testing methods.
• Result variability: Variances in hair color and individual growth rates can influence drug metabolite concentrations.

Note: Despite being commonly termed "hair follicle tests", this testing analyzes the hair strand rather than the follicle located beneath the scalp.
