Hair Follicle Drug Testing - Belgrade, MN

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive historical record of alcohol or drug use by embedding biomarkers within the strand as it grows. When harvested near the scalp, hair can offer an approximate detection span of three months for alcohol and drugs. The process of collecting hair is straightforward, tampering is relatively challenging, and shipment is convenient.

A sample measuring 1.5 inches of roughly 200 hair strands (the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the perfect sample size for both screening and verification. For EtG, additional tests, and/or those exceeding 10 panels, a sample of 150mg is advised. We suggest using a jeweler’s scale for accurate weighing of the sample. If scalp hair cannot be obtained, an equivalent quantity of body hair can be used. The term head hair specifically refers to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The lab processing of a drug test result includes four major stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves incorporating a sample into a lab’s system as the first step. This process includes ensuring that the sample is sealed and transported correctly, 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 conducts an initial swift assessment for drug abuse. While it provides a cost-efficient method for excluding drug use in most cases, a positive result from Screening requires confirmation to hold up in court. Samples deemed presumptively positive during Screening necessitate additional confirmation.

Should a sample show a presumptive positive in the Screening stage, further hair is sourced from the original sample to prepare for Extraction. Here, drugs are retrieved from hair at much lower concentrations compared to other methods (such as urine or oral fluid), explaining why hair drug testing is the most challenging methodology.

Any screening result indicating positivity is confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation when necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and conforms to ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection period: Hair drug tests can identify drug use lasting up to 90 days, unlike urine tests which have a shorter detection period.
• Hard to manipulate: It is exceedingly difficult to falsify a hair drug test, thereby enhancing result accuracy.
• Records historical use: It can illustrate a drug use trend over an extended timeframe, not just recent activity.

Limitations:

• Inability to detect recent use: It generally requires 5-7 days for drugs to become detectable in hair.
• Expense: Typically, hair drug tests are pricier than other drug testing methods.
• Result variability: Elements such as hair color and personal hair growth variations can influence drug metabolite concentration within the hair.

Note: Often termed as "hair follicle tests", the test evaluates the hair strand itself rather than the follicle beneath the scalp.
