Example- * VDRL test to detect syphilis in pregnant women.
* Pulmonary TB in chest symptoms.
* Hypertension. * Cervical cancer. * Breast cancer. * Diabetes mellitus.
⇒ Screening tests results are arbitrary & final case finding is not final but modifies the light of new evidence.
⇒ Screening is based on one criterion, but case finding is base on evaluation of a number of symptoms.
⇒ Screening is less accurate & less expensive, but case-finding is more accurate & more expensive.
⇒ Screening is not a basis for treatment but case finding is used as a basis for treatment.
⇒ In screening initiative comes from investigator or agency providing cure, but in case finding, initiative comes from a patient with a complaint. So, screening & case findings are not synonymous.
