It is very understandable that you have doubts. Do you have a fear of needles, are you still not sure which research suits your situation or do you just want more information before making a choice?

We collaborate with the medical laboratoryMVSZ dr. Stein + Kollegen. The laboratoy is ISO 15189 certified.

Unfortunately, at the moment we only offer tests for people over the age of 18. Our advice is based on adults and the reference values ​​from the laboratory are also for 18 years and older.

We are working hard to be able to test people under the age of 18 in the future.

You can only book a health check for yourself and you can book one at a time
If you want to have several markers from different health checks tested, we advise you to book Total Health. In this health check we test for all markers from the offered health checks.

It is currently not possible to have blood drawn at another location outside Amsterdam, Rotterdam and the surrounding municipalities. We are doing everything we can to get national coverage as soon as possible, but that is not yet the case.

If you live outside the regions where we are currently active and would like to conduct an investigation, please contact [email protected] and we will make an appointment at our head office in Amsterdam.

A lifestyle questionnaire will be sent by e-mail prior to the appointment with the nurse. This lifestyle questionnaire – tailored to the health check you have chosen – contains questions about your habits (eating, sleeping, exercise), any complaints and/or medication use and lifestyle. The questionnaire must be completed and returned before the appointment. During the collection appointment, the nurse will note some additional information such as blood pressure, waist circumference and heart rate, etc.

The lifestyle questionnaire consists of questions about your diet, sleeping and daily habits. Questions are asked about the frequency/duration of sporting activities. Some health checks also ask about medical history and use of medication. You will also be asked about physical and mental health symptoms.

We work with personal data and medical data and consider Data Security to be of paramount importance. All medical data is stored separately from personal data in a secure environment, so that they can never be matched with each other. Besides the date of birth, the results do not contain any personal data. The doctor and coach can only view the file of the assigned client. The results will be sent by e-mail via Zivver’s secure environment.

At the moment it is only possible to book a blood sample on location in Amsterdam, Rotterdam and the immediate vicinity. If you enter your address outside of these regions at checkout, it will not be possible to pay. It is possible to schedule a blood collection at the PREPTIC headquarters in Amsterdam. In that case you can contact [email protected] for an appointment.

All nurses who work for PREPTIC are BIG registered and trained to take blood. All nurses who collect blood samples for PREPTIC have also undergone additional training in advance. The nurses will always identify themselves with a PREPTIC staff card with their BIG registration number.

If you develop serious complications or if you are concerned, always call the general practitioner (post).

We describe some possible complications:
– A bruise or bruising may occur at the puncture site.
– The puncture site may be sensitive.
– Very rarely, bleeding can occur, especially in people with clotting disorders or if blood-thinning medicines are used. If bleeding occurs, press the wound well and contact the nurse or a doctor.

It is important that you have some time to sit quietly with the nurse in a private room.
Do not eat or drink more or differently than you are normally used to, so skip your colleague’s cake.
Make sure you have something to eat or drink with you after the blood collection to stabilize your blood sugar level. You will receive some dried fruit to eat after the blood collection from the nurse.

Our strength is that we come to the client’s location to collect the blood. This saves a lot of time and therefore costs for the client. If it is more convenient for you to come to the head office in Amsterdam or if we are not yet active in your region, we would be happy to make an appointment with you.

Hemolysis can occur if cell damage has occurred during preparation or storage, causing the red blood cells to secrete hemoglobin. However, this is not always visible to the naked eye. As a result, the results of some markers, such as potassium, LDL and AST, may be different.

The possible causes of hemolysis are diverse. The causes can be found in all aspects of the preanalytical phase; collection, transport and storage. For you as a customer, it is especially important that you have the collection done in peace. Too much stress or too high a heart rate can promote hemolysis.

The reference value (or normal value) is usually not a value, but an interval within which the outcome of that examination ‘should fall’ for a particular examination. The reference values ​​depend on age, gender and other data, for example how long before the consumption was eaten.

In addition, reference values ​​depend on the analysis method used to determine them. This means that for the interpretation of a test result, reference must always be made to the corresponding reference values. Our doctors will always assess the result in conjunction with the lifestyle questionnaire.

The results show the blood values ​​that we measure from your blood. If a marker is shaded red, your value deviates from the reference value.

The doctor will write an Expert Advice based on the laboratory results and your completed questionnaire. Here is an example of such an Expert Advice.
