Common Questions
I am perfectly healthy, but my doctor wants me to have a series of screening tests every year or so. Why ?
Screening tests are used in periodic checkups for two reasons. Firstly, such tests can detect abnormal conditions at an early stage, when they may be most effctively treated. Secondly, screening tests performed at regular interval can reveal changes in the body that, while still in the normal range, may indicate developing problems. Armed with such information, a doctor might suggest something as simple as a change in diet. Screening tests are a diagnostic aid only, and should be interpreted in the light of physical symptoms and signs.
Many valuable screening tests are simple and inexpensive and can be performed in the doctor's own surgery or in a nearby laboratory. These include measuring blood pressure, testing the blood or urine, or taking a cervical smear.
