Hair Follicle Drug Testing - Downer, MN

What it is, How it works

Hair analysis has become recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended timeline of alcohol and drug usage by encapsulating biomarkers within the strands of hair as it grows. When gathered near the scalp, hair can offer a detection period of up to around 90 days for substances. Hair is straightforward to collect, relatively hard to tamper with, and convenient to transport.

A 1.5-inch segment of approximately 200 hairs (similar to the width of a #2 pencil) nearest to the scalp provides about 100mg of hair, which is the optimal sample for both screening and verification. For EtG, additional tests, or screenings beyond 10 panels, a 150mg sample is suggested. It is advised to weigh the specimen using a jeweler’s scale. In cases where head hair is not present, a similar quantity of body hair can be used. The term head hair specifically pertains to scalp hair. Body hair encompasses all other types of hair (e.g., facial, axillary, etc.).

Process Overview

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

Accessioning consists of the initial handling of a specimen within a lab's system. It includes confirming that the specimen was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry that isn't covered by an electronic chain of custody process.

Screening involves a preliminary examination for drug use. Though Screening is a budget-friendly approach to exclude drug consumption in most samples, a positive result must be confirmed to hold up in court. Samples with a presumptive positive result in Screening require additional confirmation.

Should a sample register presumptively positive during Screening, additional hair is derived from the initial sample and readied for Extraction. In this process, drugs are extracted from hair at significantly lower levels than in other methods (e.g., urine, oral fluid), which is why hair drug analysis is considered the most challenging technique to execute.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples registering presumptive positives are cleansed before confirmation as required. The comprehensive laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and adhering to the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify substance use for up to 90 days, in contrast to urine testing which has a shorter detection span.
• Hard to deceive: It is extremely challenging to manipulate a hair drug test, resulting in more precise findings.
• Yields historical insights: It can reveal a usage trend over time, and not merely recent consumption.

Limitations:

• Does not detect recent use: It requires approximately 5-7 days for drugs to be identified in hair.
• Expense: Hair drug tests are typically more costly than other testing techniques.
• Diverse results: Variables like hair color and individual differences in hair growth can influence the level of drug metabolites present in the hair.

Note: Although commonly called "hair follicle tests", the testing examines the hair strand and not the hair follicle located below the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Downer, MN, the advantages of hair follicle testing over urine tests are notable. Hair testing boasts a significantly longer detection period, allowing for identification of substance use up to 90 days prior.
