Hair Follicle Drug Testing - Highland, MN

What it is, How it works

Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drug usage by embedding biomarkers in the fibers of the growing hair strand. If collected near the scalp, hair can deliver a detection time frame of up to roughly three months for alcohol and various drugs. Hair is straightforward to collect, somewhat challenging to adulterate, and easy to transport.

A 1.5-inch cut of about 200 strands of hair (equivalent to the thickness of a #2 pencil) closest to the scalp provides 100mg of hair, the optimal sample for analysis and validation. For EtG, enhancements, and/or testing above 10 panels, 150mg of the sample is suggested. It is advised to weigh the sample using a jeweler’s scale. If scalp hair is not obtainable, a comparable amount of body hair may be utilized. When mentioning head hair, we refer exclusively to scalp hair. Body hair encompasses all other hair types (e.g., facial, axillary, etc.).

Process Overview

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

Accessioning involves the preliminary handling of a sample within a laboratory’s framework. This step includes confirming that the sample was properly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry that was not accomplished by an electronic chain of custody procedure.

Screening entails an initial brisk assessment for drugs of misuse. Although Screening is a cost-efficient approach to rule out drug consumption in the majority of samples, a positive screen necessitates confirmation to be valid in legal proceedings. Any samples that test presumptively positive in Screening must undergo a secondary confirmation.

If a sample tests presumptively positive during the Screening phase, additional hair is retrieved from the original specimen and prepped for Extraction. At this stage, drugs are isolated from hair at a much lower concentration than in other approaches (e.g., urine or oral fluid), which is why hair drug testing is considered the most challenging methodology to execute.

Confirmation of any positive screening outcome is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptively positive are cleansed before confirmation as required. The entire laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair label and the conformity to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, which is longer compared to urine tests that have a shorter detection period.
• Challenge to manipulate: It is notably hard to manipulate a hair drug test, increasing the reliability of the results.
• Supplies historical data: It can reveal a pattern of drug consumption over a duration, not merely recent usage.

Limitations:

• Unable to detect recent usage: Drugs typically become detectable in hair only after approximately 5-7 days.
• Expense: Hair drug tests are usually more costly than other drug examination methods.
• Result variability: Elements such as hair color and individual variations in hair growth can influence the concentration of drug metabolites in hair.

Note: Although frequently referred to as "hair follicle tests", the examination analyzes the hair strand rather than the follicle beneath the scalp.
