Detection of fungal species

If there is a fungal infection on the skin (on any part of the body), hair and nails, it is an important success factor for a targeted therapy to know where the source of the infection is and/or who is the carrier of the fungus (e.g. human or animal carriers).

Normally, it takes a lot of time to accurately diagnose a fungal culture. It can take up to six weeks for a result from the laboratory to be available. The DermaGenius system, which we offer in our practice at Vienna Central Station, is a PCR-based method for detecting fungal species that cause skin, hair and nail infections. Compared to classic methods, this method enables a timely diagnosis as well as increased sensitivity and specificity.

Diagnosing food intolerance - painlessly and quickly with the Gastrolyzer

In our medical center we work with the gastrolyzer, an H2 breath test, to determine any food intolerance quickly and painlessly. The gastrolyzer is a hydrogen breath test device with which functional intestinal diseases and, in particular, food intolerances can be determined through the patient's breath. It measures the hydrogen content of the breath, which is created by the bacterial decomposition of carbohydrates in the large intestine. These reach the lungs via the body's own circulation and can thus provide information about incompatibilities.

Cost per test: 90 € (not covered by health insurance)


Alex2 - Detailed analysis of allergens

With this modern test technology, the Allergy Explorer (Alex2), all relevant allergen sources can be identified. For repeatedly sensitized patients, or in the case of ambiguous clinical information, the conventional method to determine individual allergens is often time-consuming, limited by health insurance company laboratory restrictions, and can be as painstaking as searching for a needle in a haystack.

In such cases, a comprehensive »allergen screening« provides a clear picture of the sensitizations and therefore provides helpful support for the correct diagnosis and avoidance of exposure.

Examination of specific IgE against almost 300 allergens, including almost 120 extracts and 180 allergen components. The test therefore covers more than 90% of the possible type I allergen sources. All that is needed is 1 ml of blood.

Cost per test: 250 € (not covered by health insurance)

review review
  • Thank you Dr Bisschoff. The medicine you prescribed worked like a bom! I appreciate the time you took to descibe my illness in simple terms and the lifestyle changes I need to make to manage my condition. Many thanks!

  • I traveled from London to see Dr. Johannes Bisschof for wrinkle treatment. I was extremely impressed with my wrinkle treatments. He has a very 'natural look' approach and after everyone asked me why I look younger and more relaxed I will definitely have it done again. I have also asked him advice on my skin texture and he suggested 2 creams and my skin has never looked this good. I feel 10 years younger. I can highly recommend him!

  • Dr Bisschoff used a laser to treat my skin scars. I was happy with the package that he offered. He is knowledgeable, friendly and I loved the end result.

  • Dr. Bisschoff was absolutely wonderful and a great help. He took time to make sure I was comfortable, spoke incredible English, and explained everything in a careful and detailed manner. Thanks to his help, my skin condition was solved! I would recommend him to anyone.
  • Best dermatologist in Vienna. Really cares about his patient. He is a very good listener. He spent as much time as its needed and he doesn't rush patient. His aim is actually to help people not only earn money (like some of doctors tend to do). On the top of all of that he is really positive person and he explains everything in the proper manner.



  • Excellent doctor, extremely attentive! One of the best medical experiences I had.
