FAQ 13C Products 

How can I avoid spreading viruses from breath samples in the room?

You may connect a changeable filter to the device outlet.

What shall I know about taking a breath sample?

Please see this video instructions.

I don’t know what device is right for me.

Just have a look into our Device Selection Guide.

How to avoid the error ‘CO2 concentration too low’?

Make sure the breath bags or tubes are blown in a proper way. Please follow that video instructions.

If you are working with the FANas, the needle and/or the tubes may be blocked by particles originating from the gaskets of the tubes.
Switch to your spare needle+tubes set and clean the removed parts mechanically or using compressed air.

FAQ H2 Products 

I got a question regarding the LactoFAN2 operation.

Please view our product video and have a look into the Instruction for Use.

How shall patients be prepared for a H2 breath test?

The day before the test there shall be a low-fiber diet. Before the test a 12 hour fastening is neccessary; teeth brushing is recommended and a beverage free of sugars allowed 1…2 hours before the test.

I don’t know how to dose the substrate.

There is a H2 test protocols overview.
If you got further questions you may find the handbook Hydrogen Breath Tests useful.
