DNA Liver passport examination + 1 hour consultation

Why a DNA Liver Passport examination?

With the (DNA) Liver Passport it is possible to preventively map out which medications you are likely to react abnormally to. In your personal liver passport you can see which enzymes play a role. Also herbs, supplements, nutrients and other medications that have an inhibiting or stimulating effect on enzymes are mapped. 

How people respond to nutrients, herbs, dietary supplements and medications can vary from person to person. For example, curcumin and caffeine are not processed at the same rate by everyone. This is partly due to genetic variations, which affect how enzymes work.

The liver passport gives you all the insights you need about how you react to supplements and medication. Perhaps the drug does not work or side effects occur, which can be related to how the liver works. During the hour-long consultation, one of our therapists will explain the liver passport and make the personal recommendations tangible for you. 

The following enzymes are analyzed:

ABCB1 transport protein, ALDH2 enzyme, BChE enzyme, COMT enzyme, CYP1A1 enzyme, CYP1A2 enzyme, CYP1B1 enzyme, CYP2A6 enzyme, CYP2B6 enzyme, CYP2C19 enzyme, CYP2C8 enzyme, CYP2C9 enzyme, CYP2D6 enzyme, CYP2E1 enzyme, CYP2F1 enzyme, CYP3A4 enzyme, CYP3A5 enzyme, CYP4F2 enzyme, DPYD enzyme, Factor V Leiden, F2, PROC+, PROS1+, SERPINC1, G6PD enzyme, GSTM1 enzyme, GSTP1 enzyme, GSTT1 enzyme, HLA-A*3101, HLA-B*1502, HLA-B*5701, IL28B, MTHFR enzyme, NAT1 enzyme, NAT2 enzyme, NQO1 enzyme, NUDT15 enzyme, PON1 enzyme, SLCO1B1 transporter protein, SULT1A1 enzyme, SULT1E1 enzyme, TPMT enzyme, UGT1A1 enzyme, VKORC1 enzyme.

What can you do with the results of a DNA health test?

You will receive your personal results digitally. To prevent it from becoming a theoretical story, all this information is aimed at coming up with personal recommendations that are tangible for you. With these recommendations you will walk through the results and how you can work with them together with our therapist in a 1-hour consultation.

How does a DNA test work?

The DNA test is a self-test that you can easily and quickly take at home. After your order, you will receive the DNA test kit at home. Just take a sample of saliva and send it via the return envelope. Your sample will be examined in a certified European laboratory for a reliable result. Six weeks after sending your sample you will receive the results and you can go through them with our therapist after scheduling your consultation. 

Schedule an appointment

You can schedule an appointment live at our Rotterdam office or make an online appointment. Be aware that it really is an investment in yourself, where live often comes across better than online (provided of course you live far away). Allow yourself this moment to get everything out of it.

Cancellation is possible up to 7 days before the appointment due to availability. Appointments can be rescheduled up to 72 hours in advance.

Notice! After purchase, you will receive your appointment confirmation within 24 hours. After 5 p.m. or on weekends it may take a little longer. We will confirm your appointment the next business day.

At the time you book a DNA liver passport examination + consultation, the process is as follows:

Step 6: You will be sent an online questionnaire with questions about your diet, sleep and lifestyle.

Step 7: Complete this questionnaire completely and honestly for the best possible advice.

Step 8: After completing the questionnaire, our therapists will receive your request and start working on it as soon as the test results are received.

Step 9: Live session? You can park for free in front of the door and you will be welcomed at our office.

Step 10: At the time you have your consultation (1h), your therapist will have a comprehensive and customized consultation to discuss.

Step 11: During the consultation, there will be room for questions and you will get lots of information on how to improve your lifestyle, sleep, relaxation, exercise, nutrition and supplements.

Step 12: After the advice, you will also receive your advice digitally so you can implement it in the coming time and have a clear overview of what you can do.

Step 13: Depending on what you need, we will see you back in the office or help you move forward in a way that suits you.

Who is our therapist?

"My passion for this profession started 12 years ago because I was struggling with all kinds of health issues myself; a major imbalance that expressed itself in my gut, joints, hormones and mental health. Like no other I know what it is like to be told, sorry madam this is it and there is nothing more we can do! And to be able to prove otherwise by working on my lifestyle and my brain balance" is proof that we can do much more than we think, if only we are aware of what we are doing with appropriate information."

''It was a very nice, open conversation with Marieke Kok. She has a lot of knowledge and makes a nice link from theory to practice, so that the information obtained can be applied immediately.''

DNA Liver Passport Examination

''Very glad I gave myself this gift, it's a cool insight for the rest of my life, with a beautiful book to go with it that literally says everything, what you can improve, what sleep type you are, how your stress is genetically processed, what vitamins and minerals you absorb less well and which ones well. It was really cool how I was guided by Kirsten, she is my therapist and helped me on my way. She gave me beautiful new insights. Which I am going to work with!
