General information

WinAlldat Net is an allergological documentation system focussing on late-type allergies. However, the documentation and administration of immediate-type test substances and test series are also supported as part of the computerised documentation. The anamnesis is based on an IVDK-compliant anamnesis form for recording contact allergies as part of a multi-centre study. Thanks to the modular structure, clinic-specific extensions such as forms and reports are possible.
