Hair Follicle Drug Testing - Blue Earth, MN

What it is, How it works

Hair assessment has emerged as a significant method for identifying the consumption of drugs and alcohol. Hair encapsulates a comprehensive historical record of alcohol and drug intake by embedding markers in the fibers of the growing strand. When gathered close to the scalp, hair can reveal a detection period of up to approximately 3 months for substances. The collection process is straightforward, not easily tampered with, and facilitates convenient shipping.

A sample measuring 1.5 inches, containing around 200 strands of hair (roughly the thickness of a #2 pencil) nearest to the scalp, yields 100mg, the preferred sample size for analysis. For EtG tests, extra services, and/or assessments including more than 10 panels, a specimen weighing 150mg is advised. Utilizing a jeweler’s scale is recommended for measuring the specimen. In the absence of scalp hair, a similar quantity of body hair can be gathered. When mentioning head hair, we mean scalp hair specifically. Body hair encompasses all other types, such as facial and axillary hair.

Process Overview

The primary stages in processing a laboratory drug test result are comprised of Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial processing stage where a sample is incorporated into a laboratory’s system. This phase includes ensuring that the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any remaining data entry absent from an electronic chain of custody system.

Screening denotes a preliminary swift examination for misuse of drugs. Despite Screening serving as a cost-effective method to exclude drug use in the majority of cases, a positive screen mandates confirmation for it to be permissible in legal settings. Any samples showing preliminary positive results in Screening require further verification.

Should a sample display presumptive positivity during Screening, additional hair is extracted from the primary specimen, setting the stage for Extraction. At this phase, the concentration of drugs extracted from hair is considerably lower than found in other methods (like urine or oral fluid), thus hair drug screening is acknowledged as the most intricate methodology.

Confirmation of any positive screen findings is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleaned before confirmation as required. The entire lab process from Accessioning through Confirmation is scrutinized 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 assessments can detect drug use up to 90 days prior, in contrast to the shorter window of urine tests.
• Resistance to manipulation: Cheating a hair drug test is highly challenging, leading to more accurate outcomes.
• Supplies past usage information: It can illustrate a drug use pattern over a period, not merely reflecting recent use.

Limitations:

• Inability to identify recent consumption: Detection of drugs in hair takes about 5-7 days.
• Expense: Hair drug tests typically incur higher costs than alternative drug testing methods.
• Result variability: Elements like hair color and personal differences in hair growth can influence the drug metabolite levels in the hair.

Note: Although often termed as "hair follicle tests", the examination focuses on the hair strand itself rather than the follicle beneath the scalp.
