Pre- and post-test probability
Probabilities of the presence of a condition

Pre-test probability and post-test probability are the probabilities of the presence of a condition before and after a diagnostic test, respectively. Post-test probability, in turn, can be positive or negative, depending on whether the test falls out as a positive test or a negative test, respectively. In some cases, it is used for the probability of developing the condition of interest in the future.
“Pre- and post-test probability” enters the record as probabilities of the presence of a condition. Crown Archives preserves that source wording while asking what Pre-, post-test and probability can confirm, complicate or overturn.
Why this record matters
“Pre- and post-test probability” is worth following because a concise public description often conceals a longer documentary argument. Here, Pre-, post-test and probability provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 17, 2026.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
