What it means
A "Diagnostic Test" intervention means the study is about a test — an imaging method, a laboratory test, a screening tool — rather than a treatment.
Why it matters if you take part
Taking part usually means having the test (and often a comparison test); it does not usually mean receiving a treatment.
