General information

WinAlldat Net is an allergological documentation system with a focus on late-type allergies. However, the computer-assisted documentation also supports the documentation and administration of immediate-type test substances and test series. The anamnesis is based on an IVDK-compliant anamnesis form for the recording of contact allergies within the framework of a multi-centre study. Due to the modular structure, clinic-specific extensions such as forms and reports are possible.

Development of the WinAlldat Net Software

The WinAlldat Net software 2.0 was installed in June 2015 in the functional area of allergology at the University Medical Center Göttingen (UMG) as a network version on 4 PC clients within the scope of a beta test. Currently, the WinAlldat Net Software 2.0 R18 is used in more than 50 IVDK centres. WinAlldat Net Software 2.0 is available for all IVDK associated hospitals at By default, WinAlldat Net uses the MS Access database format (mdb).
