How should it be used?
Isabel, like any symptom checker, will not be able to tell you what your diagnosis is. What it can do is suggest some diagnostic possibilities based on the symptoms that you have entered into the system.
The most important step in using Isabel is the symptoms you enter. This can clearly be a problem for a layperson as often it is hard to accurately describe your own symptoms. If you have already seen your doctor about your symptoms, he or she may have told you what the medical terminology is or described them more precisely. If you do not have this then simply try your best to describe the symptoms that are affecting you.
Try to enter the most important and initial ones first and then look at the results before adding others. You can also enter abnormal test results if you have them. However, you must enter the meaning of the result, such as high, low or whatever the medical term is, rather than the number. The system understands text but not numbers.
When the results appear you may feel rather daunted or alarmed, as there will be several diagnoses and some could be very serious. The suggested diagnoses are not ranked in an order of likelihood for you but on the basis of how well what you entered matches Isabel’s database of diseases. From the list you should end up with a short list of 2-3 possibilities that you can then discuss with your doctor. A judgement as to which diagnoses are most probable for you and should be further investigated will then need to be made by your doctor working with you.
