Markers: eGFR
The results of this survey are usually available within 24 hours.

What is eGFR?

The abbreviation of eGFR is estimated glomerular filtration rate. This estimate is used to get an idea of the glomerular filtration rate (GFR). Glomeruli are small filters in the kidneys. They ensure that waste products are removed from the blood and that important substances remain, such as proteins and blood cells. The GFR shows how much blood is filtered by the glomeruli per minute The eGFR can be used to determine how well the kidneys are functioning.

What do we determine during an eGFR examination?

With an eGFR blood test, the kidney filtration rate is estimated based on a calculation. This is based on the amount of creatinine in the blood, age, gender and race. When kidney function is reduced due to damage or a condition, it decreases the filtration speed and therefore more waste products enter the blood.

When to opt for an eGFR test?

An eGFR blood test is recommended when:
  • You want to have your kidney function examined
  • There is a suspicion of a kidney disorder
  • You have complaints that are consistent with a kidney disorder, such as urinary problems, pain in the back at the level of the kidneys, high blood pressure, or swelling (around the eyes, wrists, abdomen, and / or ankles)
  • You have an increased risk of kidney damage, such as with diabetes

Why get your eGFR tested?

With the help of this test you can get a clear picture of the functioning of the kidneys. This way, where necessary, further research can be done or appropriate treatment can be looked at.

The accuracy of the test for eGFR is conducted through ISO-certified laboratories. The accuracy of a test method is expressed in terms of specificity and sensitivity. However, the most important aspect is that the results are interpreted and accepted among general practitioners and hospitals. This is the case with our venous samples. Mutual acceptance may not always be present due to potentially reduced reliability with a capillary sample.
Most tests generally take 24-48 hours. Tests that go through an LC-MS method generally take longer, think about an average of 3-7 working days. Additionally, it also depends on the location. Some locations do the analysis themselves and others outsource it to another lab.
Interpreting the results of eGFR is not always easy and should be seen in the broader picture, along with anamnesis and physical examination. In the doctor's advice section, the query in which you can already outline your complaints is taken into account, otherwise, the results are interpreted in conjunction with the other results. If necessary, the doctor can call to ask about physical abnormalities. You don't have to interpret the results yourself because there is always advice and explanation from the doctor.
If the results of the test for eGFR are clinically significantly abnormal, the doctor will contact you by phone. If you are not reachable, you will receive an email. This includes advice and an explanation of the abnormal results and what you can do about them. If you need a prescription or referral, we can help with that.
The costs of eGFR can be found on the product page. Depending on your insurance and additional packages, you may be reimbursed for these costs for eGFR. For example, tests for IVF treatment are often reimbursed. After your order, you will receive an invoice that you can submit to your insurance.
The ordering process is easy. You can add a eGFR test or the tests you want to your shopping cart. In step two, you fill in your details and pay. Then you will receive an email confirmation and you can go to a collection location. After you have been there, you will receive the results of the eGFR test in your Portal.
We are certified-ready according to the NEN 7510 and 7512 standards for secure data transfer in healthcare. The Portal is secured with two-factor authentication. Your data is also encrypted. We do not send the results of eGFR to third parties without permission, not even to your general practitioner without your consent.
The blood test for eGFR must take place at one of the collection locations we provide. At certain locations, it is possible for a phlebotomist to come to you. You can indicate this during checkout. An appointment will then be made as soon as possible to come to your home.
You can easily make an appointment for eGFR blood test after your order in your Portal. You can visit almost daily in all major cities in the Netherlands. In smaller cities, you can visit on certain days. At certain locations, it is also possible to visit on weekends.
An interpretation by a doctor or an explanation is included in the eGFR test. The explanation takes into account the query that you can specify in your Portal after ordering.
For blood tests, we always use venous sampling. This is the gold standard for blood collection. Over-the-counter tests, such as a finger prick test, use the capillary route for blood collection. These do not always give the same results and the accuracy depends on how, where, and with which technique the collection is done. The advantage, of course, is that the test is easier and less painful to take.
You can always pay with iDeal and credit card (VISA, Mastercard, and Amex). This also includes Apple Pay. The phlebotomists at the collection location cannot accept cash payments.
The results of Labplusarts can be shared with your general practitioner at your request. However, you can also easily arrange this yourself by downloading the result in PDF format. Because we use comparable test methods as the general practitioner, the results are interchangeable and comparable so that comparisons can be made well.
