Hair Follicle Drug Testing - San Antonio, FL

What it is, How it works

Recognized as a robust tool, hair testing is frequently utilized for identifying drug and alcohol consumption. Hair offers a prolonged record of alcohol and drug intake by encapsulating biomarkers within the strands of the growing hair. Gathering hair close to the scalp can present up to an estimated three-month detection period for alcohol and substances. The collection of hair is straightforward, relatively tamper-resistant, and easily transportable.

Approximately 200 strands of 1.5-inch hair samples (equivalent to a #2 pencil in diameter) near the scalp yield the ideal 100mg sample for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg specimen is advisable. Using a jeweler’s scale for specimen weight measurement is recommended. If scalp hair is absent, a comparable amount of body hair is acceptable. Reference to head hair specifically indicates scalp hair, while body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

Four core steps constitute the laboratory processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning denotes the initial processing of a sample into the laboratory’s system, ensuring samples are properly sealed and shipped, generating a random LAN (Laboratory Accessioning Number), and completing any remaining data entry omitted by an electronic chain of custody system.

Screening is a preliminary, swift analysis for substances of abuse. Though economical in excluding drug use in most samples, a positive screen demands confirmation for court admissibility. Presumptively positive samples from Screening require secondary confirmation.

Should a sample be presumptively positive during Screening, additional hair is taken from the original specimen and prepped for Extraction. In this phase, drugs are extracted at much lower concentrations compared to alternative methods (e.g., urine or oral fluid), attributing to the challenging nature of hair drug screening.

GC/MS, GC/MS/MS, or LC/MS/MS methods facilitate Confirmation of any positive screening outcomes. Presumptive positive samples undergo a washing process prior to confirmation as necessary. The entire lab procedure from Accessioning to Confirmation undergoes review under CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection capability: Capable of identifying drug use up to 90 days, surpassing the shorter detection span of urine tests.
• Minimized cheating risk: It is notably challenging to cheat a hair drug test, enhancing result accuracy.
• Longitudinal data provision: Capable of revealing a drug use pattern over time beyond just recent intake.

Limitations:

• Recent use undetectability: Drugs generally become detectable in hair after approximately 5-7 days.
• Expense: Typically, hair drug tests are costlier than other forms of drug testing.
• Result variability: Aspects like hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although frequently called "hair follicle tests," the analysis is conducted on the hair strand rather than the follicle beneath the scalp.
