Hair Follicle Drug Testing - Renfrow, OK

What it is, How it works

Hair testing is recognized as an effective instrument for identifying drug and alcohol use. Hair retains a long-term record of drug and alcohol consumption by embedding biomarkers within the fibers of the hair as it grows. Hair samples cut close to the scalp can reveal a detection timeline of up to roughly three months for various substances. Hair is straightforward to obtain, moderately resilient to tampering, and convenient for transport.

A 1.5-inch segment of approximately 200 hair strands (comparable to the diameter of a #2 pencil) nearest to the scalp yields about 100mg of hair, which is optimal for analysis and validation. For EtG assessments, additional panels, or tests exceeding 10 panels, 150mg of hair is suggested. It's advisable to measure the specimen with a jeweler’s balance. Should scalp hair be absent, an equivalent quantity of body hair can be used. The term head hair specifically refers to scalp hair, whereas body hair encompasses all other types (e.g., facial, axillary).

Process Overview

The drug testing laboratory procedure comprises four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a specimen into the lab system. This step checks that the sample was securely sealed and dispatched correctly, assigns a unique LAN (Laboratory Accessioning Number), and fills in any supplementary data omitting from an electronic chain of custody.

Screening performs a preliminary oversight for substance abuse. While Screening is a frictionless means to exclude drug presence for most samples, a positive screen must be verified for judicial acceptability. Samples with a presumed positive screen require further confirmation.

For cases where Screening yields a presumptive positive, more hair is extracted from the original sample to undergo Extraction. Here, substances are drawn out of the hair at a much lower concentration compared to alternative methods (like urine or oral fluid), thus making hair drug testing the most challenging method to execute.

Positive results from screening undergo confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are cleansed prior to confirmation if necessary. From Accessioning through Confirmation, the entire test journey is accredited under both the CAP (College of American Pathologists) Hair recognition and ISO / IEC 17025 certification.

Advantages of hair drug testing:

• Extended detection period: Hair tests can capture drug use for as long as three months, compared to urine analysis with shorter spans.
• Resistance to manipulation: Successfully deceiving a hair test is difficult, enhancing result reliability.
• Archives usage pattern: Offers insight into long-term usage trends rather than only recent activity.

Limitations:

• Inability to detect recent usage: Drugs take approximately 5-7 days before they're traceable in hair.
• Expense: Hair testing generally incurs higher costs than other testing options.
• Result variability: Factors like hair pigmentation and individual growth variations can sway metabolite concentration in the hair.

Note: Although often called "hair follicle tests", the analysis targets the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Renfrow, OK, exceeds traditional urine tests thanks to superior accuracy. Unlike urine tests, which may miss longer-term usage, hair testing reveals substance use over extended periods, offering a more reliable picture of a person's history.
