HEALTH SCREENING – INTRODUCTION
Most diagnoses are made on the history alone but the majority of the others require a physical examination as well.
Few diagnoses require the use of special tests such as X-ray or blood tests, which are more often of use to confirm or deny a diagnosis already made or to establish the extent of the problem and rarely to find the diagnosis when the doctor is stumped.
Yet we have such a variety of special tests and they seem to get better all the time that both doctors and patients have come to place too great a reliance on them. Unfortunately they are all expensive and do add greatly to the costs of modern medicine.
Multiphasic health screening is a phenomenon of the availability of modern diagnostic testing which can make use of machines to test a number of blood levels at the one time.
The concept is that well people are screened for a number of different diseases in a one session effort. This usually involves a history taken by a machine where a number of questions appear on a screen and the answers are recorded by push button. A chest X-ray, ECG, breathing test, height and weight, urine analysis and a number of blood tests are also done. The results are fed into a computer and the printout forwarded to the referring doctor.
