Hair Follicle Drug Testing - Covelo, CA

What it is, How it works

Hair testing is increasingly recognized as an effective means for detecting drug and alcohol consumption. Hair captures a long-term record of alcohol and drug use by holding biomarkers within its growing fibers. When taken near the scalp, hair can offer up to around a 3-month detection period for alcohol and drugs. Hair is easy to collect, challenging to tamper with, and simple to send.

A sample of 1.5 inches with roughly 200 hair strands (similar in width to a #2 pencil) closest to the scalp yields 100mg of hair, the optimal amount for analysis and confirmation. For EtG, extra tests, and/or screenings over 10 panels, 150mg of the sample is advised. We suggest weighing the sample on a jeweler’s scale. If scalp hair is absent, a similar quantity of body hair can be gathered. When mentioning head hair, we mean scalp hair exclusively. Body hair encompasses all other hair variants (facial, axillary, etc.).

Process Overview

The four primary steps in processing a laboratory drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into a lab's system, verifying correct sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry absent from an electronic chain of custody system.

Screening is a preliminary rapid check for drug abuse. While Screening cost-effectively excludes drug usage for most samples, any positive Screening must be confirmed for court acceptance. Samples that show presumptive positives in Screening need further confirmation.

If a sample tests presumptive positive during Screening, additional hair is taken from the original sample and prepped for Extraction. Here, the concentration of drugs extracted from hair is much lower than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.

GC/MS, GC/MS/MS, or LC/MS/MS performs the Confirmation of any positive Screening results. All presumptive positive samples undergo washing before confirmation as required. The entire lab process from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair qualification and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can indicate drug use for up to 90 days, unlike urine tests that have a shorter detection period.
• Difficult to manipulate: It is extremely hard to fake a hair drug test, ensuring more precise results.
• Offers historical data: It offers a usage pattern over time, not only recent usage.

Limitations:

• Incapable of detecting recent use: It takes about 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variations: Aspects like hair color and personal differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Often dubbed "hair follicle tests", the test examines the hair strand, not the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle and urine testing in Covelo, CA, the former excels in superior detection accuracy and reliability. Unlike urine tests, hair tests provide a broader detection window.
