When should Isabel be used?

Doctors have a vast amount of knowledge to help them, but you are still the person who knows most about your symptoms, and our aim is to make you feel empowered to make suggestions and arrive at a diagnosis together with your doctor. Here are some tips that can help you through the process.

When in doubt

Often misdiagnoses are made because the symptoms are an unusual presentation of a common condition, or perhaps the condition isn’t very common so the doctor simply didn’t think about it. We all too often accept the first diagnosis we are given without questioning it, even if we doubt it is the correct one: this is the perfect time to use Isabel.

Entering your symptoms into the Symptom Checker will allow you to research all the possible conditions in your own time, find the one that best fits your symptoms, and then discuss this with your doctor.

If you just can’t decide whether you can wait to see you family doctor or should be going straight away to the Emergency Department, the ‘Where to get care’ triage function can help you make the right decision.

Using Isabel should enable you to say:

Doctor, I know you think I have disease X but could you explain why you don’t think it could be disease Y or Z which have suggested by Isabel and exactly match the symptoms I am experiencing?

How should Isabel be used?

Isabel, like any symptom checker, will not be able to tell you exactly what your diagnosis is. What it can do is either suggest some possible conditions based on the symptoms you have entered or help you decide where to get care.

Enter your symptoms in natural language

If you have already seen your doctor about your symptoms, he or she may have told you what the medical terminology is for them. But if not, simply try your best to describe the symptoms that are affecting you.

Start with the most important symptoms

Try to enter the most important and initial symptoms first. You can look at the results, then add others afterwards. This helps you refine your list of conditions without distorting it with symptoms that may not be as relevant.

Don't be alarmed

When you first see the results you may well be alarmed, but it is important to remember that Isabel's list of suggestions are just diagnostic possibilities. It is the job of your doctor to work with you to decide which diagnoses are most likely.

How long have you felt unwell?

The common symptoms of cancer are those of many less serious illnesses which is why cancers will often appear in the list and this can be alarming. The key indicator is how long you have had the symptom for; if more than 3 or 4 weeks, you should be talking to your doctor.

Knowledge is power

Each condition is linked to various knowledge sources such as the Merck Manual, Medline Plus, Wikipedia, NHS Choices etc. Read up on each condition to see how well your symptoms ‘fit’ and then decide whether to discuss your possible diagnoses with your doctor.
