Hair Follicle Drug Testing - Santa Rosa, AZ

What it is, How it works

Hair analysis is now recognized as a significant method for identifying drug and alcohol consumption. Hair offers an extended timeline of detection for substances by encapsulating biomarkers within the strands as they grow. When samples are taken close to the scalp, the detection period can extend to around three months for both alcohol and other drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A hair sample of 1.5 inches, approximately 200 strands or the size of a #2 pencil near the scalp, yields 100mg—ideal for both screening and confirmation. For EtG, additional tests, and those beyond 10 panels, a sample of 150mg is advisable. Using a jeweler’s scale for weighing the sample is recommended. If no scalp hair is accessible, a comparable quantity of body hair can be taken. References to head hair pertain solely to scalp hair, while body hair encompasses all other types, including facial and axillary hair.

Process Overview

The lab process for determining drug test results involves these main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves bringing a sample into the lab’s system, ensuring the sample's seal and shipment are intact, generating a random LAN (Laboratory Accessioning Number), and completing any additional record-keeping not covered by an electronic chain of custody system.

Screening is a preliminary check for drug misuse. Although Screening is an economical approach for excluding drug usage in most samples, a positive result requires confirmation to hold up in legal settings. Samples that test presumptively positive in Screening necessitate further confirmation.

Should a sample test presumptively positive in Screening, further hair is taken from the specimen for Extraction. During Extraction, drugs are isolated from hair at lower concentrations than other methods, such as in urine or saliva, explaining why hair drug analysis is the most complex method to execute.

Confirming any positive screen results is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptively positive are cleansed before confirmation if necessary. From Accessioning to Confirmation, the full laboratory procedure is scrutinized under the CAP (College of American Pathologists) Hair criteria and is accredited per ISO / IEC 17025 guidelines.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests trace drug usage up to 90 days, versus urine tests with their shorter detection timelines.
• Challenging to manipulate: It is exceedingly difficult to falsify a hair drug test, thus enhancing result accuracy.
• Delivers usage history: It can reveal a timeline of drug consumption rather than just recent intake.

Drawbacks:

• Cannot identify recent use: It generally takes 5-7 days for substances to become traceable in hair.
• Expense: Hair drug tests are typically pricier compared to other testing methods.
• Outcome variations: Variables such as hair color and personal hair growth rates can alter the concentration of drug metabolites in hair.

Note: Commonly referred to as "hair follicle tests," these tests assess the hair strands and not the follicles beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle tests to traditional urine tests in Santa Rosa, AZ, hair testing emerges as superior due to its longer detection period. The accuracy of hair tests provides a clearer picture of drug use history, making them more reliable for thorough screenings.
