Some patients arrive with test results and diagnoses that may be correct, yet still feel that these do not fully explain what they are living through. This question is not an attempt to attach another disease label. It began from a clinical need: to keep looking for dangerous or evolving disease while also studying the sequence, covariation, and functional consequences of symptoms as legitimate medical information.
What this record asks
Asks for a language and study design that can investigate function and therapeutic possibilities when persistent, recurrent, multisystem, time-varying symptoms are not fully captured by one diagnosis—while continuing to guard against missed disease.
What it aims to change
Defines “diagnostic remainder” not as a new disorder but as an observational field left under-described by classification, with ongoing diagnostic safety and active symptom research as parallel obligations.
Previous and next records
Where this idea came from and where it leads
- RAT-2026-001Why clinically important remainders persist after disease-centred classification
Acknowledging both the value and representational limits of diagnosis sharpens the problem.
- ASM-2026-001Publication-readiness assessment of founding problem statement v0.1
Only publication readiness of the problem statement was verified; this is not scientific validation.
- CON-2026-001Conjecture of added clinical value from temporal, contextual, symptom-network phenotypes
Proposes temporal, contextual, and network phenotypes as candidates for under-described information.
- PRO-2026-001Symptoms beyond diagnostic boundaries: scoping, observation vocabulary, and safety protocol
The problem motivates a protocol for researchable strata, vocabulary, and safety rules.
Show verification requirements and current limitations
What still needs to be established
- Stratify distinct patient groups without collapsing them into one cause or syndrome
- Specify reassessment pathways for new symptoms, red flags, and changing trajectories
- Test incremental decision value beyond diagnosis labels and symptom counts
What this record does not yet establish
- “Diagnostic remainder” is not a clinical diagnosis, causal explanation, or claim of Korean-medicine effectiveness.
