Begin With the Laboratory Foundations of RBTI
Have you been curious about the Reams Biological Theory of Ionization (RBTI) but weren’t sure where to begin?
Foundations of RBTI is a practical introductory course designed to teach students the laboratory skills and testing procedures needed before moving into professional RBTI interpretation.
RBTI uses a series of measurements obtained through urine and saliva testing. In this course, students learn how to properly collect samples, use and care for laboratory equipment, perform each foundational test, and accurately record their results.
The emphasis of Foundations is on learning to test correctly and consistently. Interpretation of the numbers, relationships between measurements, correction priorities, and practitioner-level application are taught in the RBTI Professional course.
What You Will Learn
This course provides step-by-step instruction in:
- An introduction to RBTI and its laboratory foundations
- The measurements used in RBTI testing
- Proper urine and saliva sample collection
- Laboratory setup and organization
- Use of the clinical refractometer
- Conductivity testing
- Urine and saliva pH testing
- Albumin testing
- Nitrate nitrogen (NN) testing
- Ammoniacal nitrogen (AN) testing
- Proper use and handling of testing materials and reagents
- Calibration and accuracy
- Equipment care and maintenance
- Common laboratory and equipment mistakes
- Accurately recording laboratory results
- Developing consistent testing procedures
Hands-On Laboratory Skills
Students will become familiar with the equipment and materials used in RBTI testing and learn the proper procedure for obtaining each measurement.
The goal is not simply to learn what the numbers are called, but to develop the practical laboratory skills necessary to produce consistent and reliable test results.
Who Should Enroll?
Foundations of RBTI is designed for:
- Students completely new to RBTI
- Natural health students and practitioners interested in learning RBTI testing
- Iridologists, sclerologists, wellness coaches, and other natural health professionals
- Individuals interested in learning the laboratory procedures used in RBTI
- Students planning to continue into RBTI Professional
No previous RBTI experience is required.
Preparing for RBTI Professional
Foundations of RBTI establishes the laboratory knowledge expected before entering the RBTI Professional course.
Students who successfully complete Foundations should be able to properly collect samples, identify and use the required laboratory equipment, perform the foundational RBTI tests, maintain their equipment, recognize common testing errors, and accurately record their laboratory findings.
From there, students are prepared to move beyond how to obtain the numbers and begin learning how those numbers relate to one another and how they are interpreted within RBTI.
Learn the Testing. Master the Equipment. Build Your Foundation in RBTI.
