Differential diagnosis

Please enter at least one feature (symptom, sign or investigation result) before performing the calculation.

For example, if chest pain and low oxygen saturations were present, but haemoptysis was absent, the features section should look as follows:

To add a feature that is present, start typing and then click the green arrow.

To add the absence of a feature (i.e. a 'negative' finding), start typing then click the red cross.

If you want to remove a feature from the list simply click the grey cross in the box to the right of the feature.
