Comparability depends on laboratory, method, sample type and collection conditions.

Evidence record
One measurement of an analyte describes that sample at that moment. Direction of change over time can only be read from repeated measurements taken under comparable conditions.

MethodologyWhat this evidence classification meansSeveral consistent and directly relevant sources point the same way, or a well-supported professional standard exists.
- Definition
- Several consistent and directly relevant sources point the same way, or a well-supported professional standard exists.
- What it does not mean
- It does not mean certain, universally applicable, or free of important limitations.
Plain English
What this means in practice.
The owner-facing conclusion comes before the study taxonomy.
Treat this result as one point. If the value matters, the useful next step is a repeat under the same conditions.
What remains uncertain: How much difference between two results is meaningful varies by analyte.

Structured record
What was actually studied.
Population, comparator, outcome, direction, and consistency remain separate so the claim cannot become broader than its evidence.
- Population
- Laboratory results reported for individual dogs
- Factor or intervention
- Reading direction of change from one measurement
- Comparator
- Repeated measurement under comparable conditions
- Outcome
- Whether a trend can be established
- Direction
- not_applicable
- Consistency
- consistent
- Directness note
- A statement about what one measurement can support, not about any disease.
Uncertainty
Where the conclusion stops.
Limitations are part of the conclusion, not a disclaimer added after it.
