Hair Follicle Drug Testing - Prescott, IA

What it is, How it works

The use of hair testing is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair provides a comprehensive timeline of substance use by preserving biomarkers within the fibers of the growing hair strands. When taken from near the scalp, hair samples can offer a detection period of up to roughly three months for alcohol and other substances. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches and consisting of approximately 200 strands of hair (comparable to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the ideal quantity for both screening and confirmation. For EtG tests, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is advisable. It is recommended to weigh the sample on a jeweler's scale. If scalp hair cannot be obtained, a similar amount of body hair may be used. When mentioning head hair, it specifically refers to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning is the initial processing phase whereby a sample enters a laboratory's system. This step entails verifying the proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody system.

Screening provides an initial rapid assessment for drug presence. While Screening offers a cost-effective approach to eliminate negative samples, a positive screen must undergo confirmation to hold up in legal proceedings. Any samples flagged as presumptively positive in Screening require subsequent confirmation.

Should a sample test presumptively positive during Screening, additional hair is extracted from the original specimen and prepped for Extraction. During this phase, drugs are extracted from hair at much lower concentrations than with other methodologies (such as urine or oral fluid), which is what makes hair drug testing the most challenging methodology.

Confirmation of any positive screen outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples flagged as presumptively positive undergo washing before confirmation as necessary. The entire lab process, from Accessioning to 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:

• Extensive detection period: Hair drug tests can reveal drug use for up to 90 days, as opposed to urine tests which have a more limited detection period.
• Hard to manipulate: It is extremely difficult to manipulate a hair drug test, making the results more reliable.
• Offers historical insights: It can illustrate a drug usage pattern over time, not just recent consumption.

Limitations:

• Inability to detect recent use: It generally takes 5-7 days for substances to become detectable in hair.
• Expense: Hair drug tests tend to be more costly than other drug testing methods.
• Result variations: Factors such as hair color and individual hair growth differences can influence the concentration of drug metabolites in hair samples.

Note: Despite commonly being termed as "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.
