Hair Follicle Drug Testing - Postville, IA

What it is, How it works

Hair testing is recognized as an effective technique for identifying drug and alcohol consumption. Hair captures a prolonged record of these substances by embedding biomarkers within the strands of hair as it grows. When samples are taken near the scalp, they can offer an approximate detection period of up to 3 months for drugs and alcohol. Hair samples are straightforward to gather, relatively hard to tamper with, and convenient to transport.

A 1.5-inch section comprising roughly 200 hairs (comparable to the thickness of a #2 pencil) nearest the scalp will yield 100mg of hair, which is an optimal quantity for testing and validation. For EtG assessments, additional tests, or panels exceeding 10, a specimen of 150mg is suggested. It's advisable to use a jeweler's scale to weigh the sample. Should scalp hair be lacking, an equivalent quantity of body hair can be collected. The term "head hair" specifically refers to scalp hair, while "body hair" encompasses all other types such as facial or axillary hair.

Process Overview

The laboratory drug testing procedure encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the initial phase of entering a sample into a lab's system, ensuring it was properly sealed and transported, assigning it a random LAN (Laboratory Accessioning Number), and concluding any additional data entry that an electronic chain of custody system doesn’t cover.

Screening entails a preliminary inspection for illicit drugs. Although Screening offers a cost-efficient means to exclude usage in most cases, a positive result must be verified to be legally acceptable. Samples with an initial positive result in Screening require further confirmation.

For samples considered positive at the Screening phase, more hair is extracted from the original sample for the Extraction process. During this phase, drugs are isolated from hair at significantly lower concentrations than other testing methods (like urine or oral fluid), which is why hair testing is notably challenging to perform.

Verification of any positive screening result employs techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a presumptive positive result undergo washing before confirmation as necessary. The laboratory process from Accessioning to Confirmation is evaluated against the standards set by CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug use up to 90 days prior, unlike urine tests which have a narrower detection timeframe.
• Difficult to deceive: It is challenging to manipulate a hair drug test, ensuring more precise results.
• Tracks historical use: It reveals a trend of drug usage over time, rather than just recent use.

Limitations:

• Unable to detect recent use: Drugs become traceable in hair after approximately 5-7 days.
• Expense: Hair drug tests tend to be costlier than alternative testing methods.
• Result variability: Factors like hair color and individual hair growth differences can influence the drug metabolite levels in hair.

Note: Although often termed "hair follicle tests," the assessment actually examines the hair strand rather than the follicle beneath the scalp.
