Hair Follicle Drug Testing - Round Mountain, NV

What it is, How it works

Hair testing is recognized as a robust method for identifying drug and alcohol consumption. The strands of hair provide an extended record of alcohol and drug presence by capturing biomarkers inside the fibers as the hair grows. When obtained near the scalp, hair can offer up to a roughly 3-month window for detecting alcohol and drugs. Hair is easy to collect, somewhat challenging to tamper with, and convenient to send.

A sample size of 1.5 inches consisting of approximately 200 hairs (comparable to the thickness of a #2 pencil) nearest to the scalp equates to 100mg, which is optimal for both screening and confirming. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is preferred. It's advisable to weigh the sample on a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair may be used. When mentioning head hair, it specifically refers to scalp hair alone. In contrast, body hair denotes all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning is the initial phase where the sample is integrated into the laboratory's system. This step verifies the proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and concludes any supplementary data entry not provided by an electronic chain of custody system.

Screening comprises an initial swift examination for substances of abuse. Though Screening is a cost-efficient means to exclude drug usage in the majority of samples, a positive outcome from screening requires confirmation to be legal in court. Any samples that show presumptive positive results in Screening necessitate a secondary confirmation.

If any sample exhibits a presumptive positive during Screening, more hair is extracted from the original sample and prepared for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations than in other methodologies (such as urine or oral fluid), which is why hair drug screening is the most challenging method to execute.

Confirmation of any positive screening result utilizes GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo a washing process before confirmation if needed. The full laboratory process, from Accessioning to Confirmation, is examined following both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can reveal drug use over a period extending up to 90 days, while urine tests have a shorter detection duration.
• Hard to manipulate: Cheating a hair drug test is quite difficult, increasing result reliability.
• Offers longitudinal data: It reveals a timeline of drug use, rather than just recent consumption.

Limitations:

• Inability to detect recent use: Drugs become visible in hair in about 5-7 days.
• Expense: Hair drug testing typically costs more than alternative drug testing methods.
• Result variability: Aspects such as hair color and personal differences in hair growth can influence the level of drug metabolites in the hair.

Note: Commonly termed as "hair follicle tests", the examination actually involves the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When considering drug testing methods in Round Mountain, NV, hair follicle tests clearly outshine traditional urine tests in several ways. Accuracy and reliability are two pillars that showcase this superiority, providing more dependable detection results.
