# Reading device documents

> Read clearance, predicates, specifications, recalls and IFU revisions as separate document questions.

Each explanation connects a common consumer question to exact models and original source roles. Model identity and personal clinical outcomes remain separate.

## Which device document claim needs closer reading?

Clearance, predicate comparisons, technical conflicts and revision dates need different reading questions.

The explanations follow the supporting document rather than a ranking headline. A specification conflict leads to source identity, a recall leads to tip and lot scope, and an old IFU leads to the relationship with later events.
