Hair Follicle Drug Testing - Humboldt, NE

What it is, How it works

Hair analysis is now considered an effective means for identifying drug and alcohol use. Hair offers a comprehensive history of substances, capturing biomarkers in the strands as they grow. When taken near the scalp, it enables detection of drugs and alcohol for up to around three months. Hair is straightforward to collect, relatively tamper-resistant, and easy to dispatch.

A 1.5-inch section of roughly 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp yields 100mg, the perfect quantity for analysis and confirmation. For EtG, additional analyses, and tests exceeding 10 panels, 150mg is suggested. It’s advised to measure the sample weight using a jeweler’s scale. Should scalp hair be unavailable, an equivalent amount of body hair can be taken. "Head hair" refers solely to scalp hair, whereas "body hair" encompasses all other types (such as facial and axillary hair).

Process Overview

Drug test result processing in a lab consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the preliminary handling of a sample within the laboratory’s framework. This step includes ensuring the sample’s seal and shipment are intact, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry missing from an electronic chain of custody system.

Screening provides an initial rapid assessment for substance misuse. While it is an economical method to dismiss drug use in the majority of specimens, a positive outcome necessitates confirmation to be legally defensible. Any samples preliminarily positive at Screening need further validation.

Should a sample show presumptive positivity at the Screening phase, additional hair is extracted from the initial sample for the Extraction process. Here, drug extraction from hair occurs at far lower concentrations compared to other methods (like urine or oral fluid), which makes hair drug testing particularly challenging to conduct.

Positive outcomes from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All such presumptive positive specimens undergo cleansing prior to confirmation if required. The whole lab procedure from Accessioning through to Confirmation is evaluated according to both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can indicate drug consumption for up to 90 days, a feature not shared by urine tests, which have a shorter detection interval.
• Cheating is challenging: Hair tests are hard to manipulate, enhancing result reliability.
• Historical insight: It allows for a timeline of substance use, not just recent incidents.

Limitations:

• Incapable of detecting recent intake: It takes a drug about 5-7 days to become detectable in hair.
• Expense: Hair drug testing tends to be pricier than other methods.
• Result variability: Elements such as hair color and individual hair growth rates can impact the levels of drug metabolites in hair.

Note: Though often dubbed "hair follicle tests," the examination evaluates the hair strand, not the follicle beneath the scalp.
