Why take the Protein Test?
An optimal protein intake is an important topic for athletes, but also for vegans who want to get the most out of plant-based protein sources. But for everyone else, too, looking closely at which proteins your body best tolerates can be very insightful.
Because it is not only the composition of amino acids and their bioavailability – that is, how well the protein is absorbed by our body, that counts. Finding out which proteins you can tolerate is also crucial if you want to reduce discomfort, increase your well-being and get the most out of your athletic performance.
The Protein Test gives you insights into these important topics and helps you to choose the protein sources that are suitable for you. You will also receive detailed information and tips about the various proteins.
Please note: The Protein Test will not tell you whether you are intolerant to other substances, such as lactose or gluten. Other tests need to be carried out to detect these intolerances. Lactose intolerance, for example, is an intolerance to lactose, whereas the Protein Test examines screens for intolerances to whey proteins and caseins in milk.
How does the Protein Test work?
To carry out the Protein Test, take a small blood sample from your fingertip with a lancet. Only a few drops of blood are needed.
Send your sample in the sample tube provided via a return envelope to our specialist laboratory, which analyses the number of certain IgG4 antibodies in your blood. After the analysis, you will receive a notification, after which you will be able to access your results report by logging in on our website or on the My cerascreen® app.
Please note: You will get the most meaningful results if you have maintained a varied diet and have not abstained from any of the tested proteins in the two weeks prior to collecting the sample.
What will the results tell me?
Our Protein Test results report shows you which IgG4 antibodies were detected in your blood – that is, to which foods you react.
A table will show you whether the antibody concentration for each of the 16 different proteins in your blood was low (green), medium (yellow) or high (red). This gives you an indication of whether you might be intolerant to a protein. High IgG4 values are not a concrete diagnosis. Only doctors can officially diagnose you with an intolerance – you should consider also you talking to your doctor about the results from this test.
However, observations in practice show that increased IgG4 values are often accompanied by symptoms of an intolerance. However, sometimes, high values are not accompanied by any complaints at all.
Which recommendations will I receive?
In the results report, we will tell you which proteins are well tolerated by you based on our lab analysis. You will also receive tips on how you can further investigate how to manage eliminating or reducing the proteins to which you are intolerant over the long term.
We will also inform you in detail about different proteins and how you can provide your body with the all-important amino acids. In addition, you will receive valuable tips for muscle growth. This makes it easier for you to find the diet that suits you and helps you achieve your goals.
Why are proteins so important?
Proteins are broken down into their amino acids in our bodies and are reassembled into new proteins. They are the building blocks of many important hormones; they also work as enzymes and antibodies and transport nutrients and oxygen through our blood.
In addition, proteins are involved in building and repairing muscles. That is why people who do very intensive sports have higher protein requirements – their body uses up more protein.
How can the right proteins boost your workout?
If you have a higher daily protein requirement, protein powders and drinks can help you meet these. This ensures that your body has the right building blocks to effectively build and maintain muscle after training. However, it is of course crucial that you tolerate the proteins well!
Intolerances might not only distract you from an effective workout if you’re suffering from gastrointestinal complaints, but they also cause fatigue and reduce your performance.
Which proteins does the test screen for?
The protein test analyses the IgG4 antibodies against a total of 16 protein sources.
- Chicken egg
- Whey (cow’s milk)
- Casein (cow’s milk)
- Goat’s milk (whey, casein)
- Sheep’s milk (whey, casein)
- Chicken meat
- Wheat (gluten)
- Soya bean
- Sweet lupine
What are IgG4 antibodies?
For the Protein Test, specific IgG4 antibodies are measured in your blood. The abbreviation ‘IgG4’ stands for immunoglobulins G4.
Immunoglobulins are important building blocks of our immune system. There are different classes of immunoglobulins – for example, immunoglobulin E (IgE) and immunoglobulin G (IgG). The IgG4 antibodies can block IgE antibodies, which the body uses, for example, to reduce allergic reactions.
IgG4 are specific antibodies – this means that a very specific type of antibody is produced against a very specific protein. So, for example, there are IgG4 antibodies against chicken egg proteins that are different from IgG4 antibodies against soy proteins. Specialist laboratories can precisely analyse these specific antibodies in our blood.
What are IgG4-mediated intolerances?
According to theories, an increased number of specific IgG4 antibodies can lead to defensive reactions and inflammation in the body when you eat certain foods.
Symptoms can show up with a delayed reaction – for example, the affected person might eat a certain food to which they are intolerant, but symptoms may not appear until hours or even days later.
Which symptoms are associated with a food intolerance?
Possible symptoms of IgG4-mediated intolerance are:
- gastrointestinal complaints, especially flatulence
- headaches and migraines
- wheezing and a runny nose
- skin rashes
In addition, some experts suspect that intolerances may contribute to the development of inflammatory bowel diseases.
Who should NOT take the test?
The Protein Test is not or only partially suitable for certain groups of people:
- People with infectious diseases, like hepatitis and HIV, may not use the Protein Test.
- Pregnant and breastfeeding women should only take the Protein Test under medical supervision. The given reference ranges and recommendations do not apply to people in this group; consult your medical professional for advice concerning your test results.
- The Protein Test is not intended for children under 18 years of age.
The test is not intended for diagnosing illnesses or diseases. For example, if you suffer from moderate depression or extreme pain, consult a doctor.
