MOST DIAGNSOSIS MADE FROM PATIENT HISTORY
What factors impact the reliability of a test
- Normal values
- Factors other than disease which infuence test results
-Operating characteristics
-Sensitivity and specificity - prevalance of dsease in populatuon

True or False
No test has 100% sensitivity and speficity
True
