One dimension of difference is clinician intent:
A diagnostic test is ordered to establish the probabilities of a group of candidate physiologic processes.
A prognostic test is ordered to establish the probabilities of candidate courses of the disease process.
Many tests satisfy both intentions and may be ordered with either single intention or combining the two.

help identify an already existing condition whereas a prognostic study
examines one of more factors that can predict a future condition? Is it
that diagnosis is targeted towards something bad (disease) while
prognosis is targeted towards something good (recovery)? Or is it
