Symptom Checkers and other Websites


As Patient info suggest:
“Online symptom checkers are calculators that ask users to input details about their signs and symptoms of sickness, along with their gender, age and location. Using computerised algorithms, the self-diagnosis tool will then give a range of conditions that might fit the problems a user is experiencing.”
Symptom checkers can help understanding but Patient info also consider some of the drawbacks of symptom checkers, including around the accuracy.
Symptom Checker at Patient. Check common symptoms online. | Patient

Symptom checkers are becoming increasingly more sophisticated however their accuracy is not 100% and, in some cases, it can be lower than 60%. So, these tools do not provide medical advice, diagnosis or treatment and you should always rely on a clinician to provide these and not rely on any symptom checker to help you make any decisions. However, they can provide information about common conditions. Click below to see some symptom checkers.


Importantly none of the symptom checkers are 100% accurate (some may have an accuracy less than 60%) so importantly these tools are purely designed to provide information and potentially help you understand your condition. These tools do not provide medical advice, diagnosis or treatment. Professional medical advice provided by a clinician such as a doctor should always be relied on to make decisions, and information provided here should not delay you in any way getting such advice.

PLEASE NOTE: Some sites are American so recommend you call 911 (this should be 999 for the UK) if you think you have an emergency.

All these sites offer different perspectives and different ways of presenting the information so some may find it informative to compare their symptoms in different sites.

Other websites

There are so many websites on health and so much information now available that it can be difficult to know where to go for reliable information. Some commonly used websites from the UK and outside the UK are listed. We cannot vouch for all the information on these websites and again the information should not be used for advice, diagnosis or treatment but only information and helping with your understanding. Equally this is not an exhaustive list and there are many good websites which have not been included.
