Hair Follicle Drug Testing - Knierim, IA

What it is, How it works

Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair offers an extended record of alcohol and drug intake by encapsulating biomarkers within its growing strands. When collected near the scalp, hair can reveal up to an approximate three-month period of drug and alcohol history. Hair is straightforward to gather, somewhat challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches of around 200 hair strands, similar in size to a #2 pencil, taken closest to the scalp will yield 100mg of hair, which is the optimal quantity for screening and verification. For EtG, supplemental tests, and/or panels exceeding 10, a 150mg sample is advised. It's recommended to weigh the hair on a jeweler's scale. If scalp hair isn't accessible, a similar amount of body hair may be used. When mentioning head hair, we mean scalp hair specifically. Body hair refers to all other types of hair (facial, axillary, etc.).

Process Overview

The processing of a drug test result in a laboratory includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where the sample is processed into the laboratory's system. It involves checking that the sample was appropriately sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.

Screening is an initial rapid assessment for drug substances. While Screening provides a cost-effective means to eliminate drug usage in most samples, a positive screen must be affirmed for it to be legally permissible in court. Any samples that return a presumptive positive in Screening necessitate additional confirmation.

Should a sample yield a presumptive positive result in the Screening stage, more hair is taken from the original sample for Extraction. In this phase, drugs are removed from the hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug testing the most challenging methodology to conduct.

Confirmation of any positive screening outcomes is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptive positive are cleansed before confirmation when required. The complete laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can determine drug usage for up to 90 days, compared to urine tests, which have a shorter detection period.
• Difficult to deceive: Cheating a hair drug test is exceedingly challenging, thus ensuring the accuracy of the results.
• Provides usage history: It can depict a pattern of drug consumption over time, rather than just recent usage.

Limitations:

• Cannot detect immediate use: It takes approximately 5-7 days for drugs to manifest in hair.
• Cost: Hair drug tests are generally pricier than alternative drug testing methods.
• Result variations: Aspects such as hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Though commonly called "hair follicle tests", the test actually analyzes the hair strand, not the follicle under the scalp.
