Excellent service from Swan Science

We discovered and contacted Swan Science having become aware of them through the Allergy & Free From Show. We completed a preliminary health questionnaire and then a short clinical-style questionnaire that looked at skin, gut health, immune triggers, and environmental factors. This was requested to build a clearer picture of what tests were needed and to allow for a more appropriate recommendation rather than guessing. The communication from Susan at Swan Science was faultless. We have for the first time had in-depth test results from a blood test which allows us to really understand the problem and where to go from here. Yes, it costs, but it has been money well spent and I would recommend it to anyone who has been going round in circles trying to understand their health concerns.

From feeling helpless to become my empowetef

Having had gut problems for years, my GP referred me to a colorectal surgeon where I began a series of scans because each scan revealed a problem which led to another scan. Eventually I was told I had a problem with my Pancras, liver, colon and rectum.
Worried as I had now become, no surgeon made any proposal as to how I may be helped . Attempts to fix my many problems with surgery were deemed more likely to add injury rather than heal it.
With a waiting time of a month to see a GP on the NHS, I contacted Swan Science who were offering very comprehensive stool tests and a full range of blood tests. Firstly I did the stool tests and several co-occurring reasons for my problems were suggested. In line with best practise, no diagnosis was given whilst suggestions for presenting the results to a specialist was advised. Deciding to be fully armed with information, I decided to take the blood tests with Swan Science. These.wide ranging tests were easy and painless. The results came with red flags marking
individual results that needed attention. An additional page summarised the results for presentation to a GP.
When I saw my GP he was very impressed to have every type of information before him. He had two screens and was able to cross refer findings from both the stool sample tests and the blood tests. From these results my doctor was able to understand my complex medical condition and prescribe medication. He also decided to recall me “to keep a watchful eye” at regular intervals. I am already finding some improvement in my health.
I have also learned how important the results I received from Swan Science are. I felt informed and confident when attending the GP surgery. The knowledge I had in my results meant I knew I would be heard and that my health troubles (that could not be helped by surgery) would be seen in my Swan Scoence test results as needing to be addressed
I cannot thank Swan Science enough
And to anyone who feels diffident when trying to get illness addressed, I would recommend a journey of discovery through Swan Science.
Good Health is our most important asset!

Excellent service

Excellent service, the test was delivered really quickly and the results came through within a couple of days. Having received the report, it would be incredibly helpful to be offered a follow up conversation with a nutritionist to help me fully understand and interpret how the results impact my diet and to identify the changes I can make.

I bought a food tolerance test

I bought a food tolerance test, the kit arrived in a few days and my results arrived within a week. I’ve since cut a few things out of my diet and feel much better for it. Definitely recommend getting tested.

Proper scientific testing at an accessible price point

I ordered food intolerance tests for two of my kids who were suffering in different ways and at their wits end as to how to deal with what was going on in their bodies. All the helpful advice from family, friends and dr google had them totally confused and I had always been put off by the daunting price tag of “proper” intolerance tests.

Swan science made it so easy and offers testing that is as good as any other lab and incredibly good value for money - the results came back quickly, were easy to read and highlighted foods to avoid that we would never have thought of.

A brilliant service and a game changer for anyone that is struggling with intolerance issues or is just not sure and wants to look at this with some proper scientific testing.

Would definitely recommend!

Really pleased that I undertook the intolerance test. It was simple and straightforward to order online and then to complete when the pack came. Instructions were very clear and the test results were laid out really helpfully. I have now cut out yeast from my diet, as the test highlighted this as a high intolerance for me, and I am feeling much better. Thank you!

Intolerance test

Really easy to use website, very clear. Didn't wait long for the package to arrive, clear instructions. Just post back via the post office. Received an email with my results within a few days. They are very helpful if you need to ask a question. Would highly recommend.

Glad to have helped Kerrie! Hope you see some positive changes from the information in your food intolerance report.

Rated 5 out of 5 stars

Quick and easy. Suggest a varied diet before testing.

I ordered 2 tests for myself and my partner as we have varying food issues.
The tests arrived quickly, the instructions were easy to follow and the results arrived in less than a week.
We’ve found the results really insightful based on our normal eating habits.
Now I have more understanding of the test, and how it works, I want to do another one after having a super varied diet for a couple of weeks so I can get a full scope reading of as many of the 200 food types as possible, including some of my ‘issue’ foods as I haven’t eaten some items for a few years meaning they didn’t show a reaction on my test.

Food intolerance test

I took a food intolerance test provided by Swann science. The whole process was very well explained and any questions I had were answered or explained fully and promptly. The test tested over 200 food types and the results were returned to me via email within two days. All in all a speedy trustworthy service that I wouldn't hesitate to use again.
