All our test kits are designed for customers based in the UK. The postage paid sample return envelope in your kit will not be valid outside the UK. You will need to contact a courier in the country you are located and request a service that is authorised to ship ‘UN3373 Biological Substances Category B’ items. Your sample might not get through Customs (if applicable) without this service. Samples do not require freezing or chilled packaging. Please package your sample as per the kit instructions, placing the sample in the return envelope provided in the kit. This then needs to be placed inside the packaging of your chosen courier 1. **Gut Health Test:** Biovis Diagnostik, Justus-Staudt-Straße 2, 65555 Limburg an der Lahn, Germany 2. **SIBO Breath Test:** Biovis Diagnostik, Justus-Staudt-Straße 2, 65555 Limburg an der Lahn, Germany 3. **Food sensitivity (IgG) Test:** Cambridge Nutritional Sciences, Eden Research Park, Henry Crabb Road, Littleport, Cambridgeshire, CB6 1SE ### Send in the right timeframe Make sure you return your samples within the right timeframe for your test: -
