Does the algorithm provide a diagnosis for my skin lesion?

Please be sure that the result of the algorithm is NOT A CONCLUSIVE DIAGNOSIS. The algorithm is not intended to be used for the diagnosis of skin disease. In-person examination of dermatologists is much more accurate. The algorithm provides the most relevant documents for the given images, to search for proper medical information.

How accurate is the algorithm?

The algorithm could provide more accurate information than random internet searches, and the accuracies of the algorithm were equivalent to that of general physicians. For the internet community images (Reddit), the accuracy of the algorithm was 39.2% (1st result; Top-1 accuracy) / 67.2% (1st ~ 3rd results; Top-3 accuracy).

How should I use the algorithm?

The result of the algorithm can help to obtain medical information about the signs and symptoms of highly relevant diseases. It can deliver more accurate clues than a search engine to find medical information. Please seek a doctor’s advice in addition to using this app before making any medical decisions.

Is it Free?

The use of the algorithm is FREE. 

The app crashed.

If the algorithm does not work, please access it via https://app.skindx.net in a mobile browser (Safari or Chrome).

In what setting does the algorithm work best?

The algorithm can give the most accurate advice on Asian skin lesions. The algorithm was trained and also validated on lesions from the images of the white population. However, it has not yet been validated for the black population and may show uncertainty.

What is the image quality setting?

The high-resolution setting includes the feature of lesion detection and gives better results. A low-resolution setting can be selected in the “Setting” menu if you have an internet speed issue.

Are the submitted photographs stored?

The photograph is transferred for the cloud analysis, however, we do NOT store your images. Simple having big data does not improve the performance of the algorithm. We have established a skin image dataset by annotating data published on the Internet, not user data.

How many disease classes were trained?

A total of 186 disease classes are included. Although the classifier includes monkeypox, the performance for monkeypox was not validated, and the diagnosis of monkeypox using clinical photographs is still challenging.

How many disease classes were validated?

A total of 133 disease classes have been validated. The accuracy and balanced accuracy of the algorithm were comparable with those of dermatologists in the experimental setting.
