Hair Follicle Drug Testing - Lucan, MN

What it is, How it works

Hair analysis has emerged as an effective approach for identifying drug and alcohol consumption. Hair offers a prolonged account of alcohol and substance intake by embedding biomarkers within the fibers of the developing hair strand. When collected near the scalp, hair can reflect a detection span of up to nearly 90 days for alcohol and various drugs. Hair is straightforward to collect, somewhat resistant to tampering, and simple to transport.

A 1.5-inch section consisting of about 200 hair strands (about the circumference of a #2 pencil) nearest to the scalp yields 100mg of hair, the preferred sample size for both initial and confirmatory tests. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is not present, an equivalent quantity of body hair may be gathered. When speaking of head hair, we mean only scalp hair. Body hair pertains to all other types of hair (facial, axillary, etc.).

Process Overview

The four primary phases in the laboratory evaluation of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary handling of a sample into a laboratory’s database. This encompasses confirming that the sample was adequately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry not covered by an electronic chain of custody system.

Screening consists of an initial rapid assessment for drugs of misuse. While Screening is a cost-efficient method to exclude drug use across most samples, a positive screen requires validation to be legally acceptable. Any samples that are presumptively positive in Screening do necessitate a follow-up confirmation.

If a sample is likely positive in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are derived from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), explaining why hair drug analysis is the most challenging method to execute.

Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS or LC/MS/MS. All likely positive samples undergo washing before confirmation as needed. The entire laboratory operation from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 benchmarks.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection span.
• Challenging to manipulate: It is very tough to falsify a hair drug test, enhancing the accuracy of results.
• Offers historical information: It can delineate a trend of drug use across time, not just recent usage.

Limitations:

• Unable to identify recent usage: It takes roughly 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests typically cost more than other drug testing methods.
• Result variability: Elements such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Though often called "hair follicle tests", the test actually examines the hair strand and not the hair follicle beneath the scalp
