Mierau Medical Diagnostic and Coding Method
The Eighteen Foundational Postulates
Postulate 14 Multi-Source Principle
Statement
Medical diagnostic reasoning SHOULD consider relevant information from multiple appropriate sources rather than relying exclusively on a single source of information.
Definition
Multi-Source refers to the structured consideration of medical information originating from different sources, methods, or perspectives that are relevant to the same diagnostic question.
Sources may include, for example
- patient self-report,
- observations by third parties,
- clinical examination,
- laboratory investigations,
- imaging,
- functional investigations,
- specialist assessments,
- previous medical records.
Different sources may provide complementary, confirming, or contradictory information.
Principle
Relevant information from different sources SHALL be considered together, while the individual nature, limitations, and evidentiary value of each source remain distinguishable.
Combining sources does not mean treating all sources as equally reliable or as independent confirmation.

Key Message
Bring the relevant sources together - but never confuse more information with stronger evidence.
