“Everything is normal” and “something has changed” can both be true.
Most routine bloodwork is built to identify a current problem. It is not always built to show you the direction your own markers have moved over time.
That is where a personal baseline becomes useful.

You cannot build that old baseline retroactively. But you can start building one now.
Is there anything you wish you had measured when you felt better?
