If you have been infected with Covid-19 (the coronavirus), the following physical complaints, among others, play a role:

  • Pulmonary complaints, such as dry cough, sneezing and sore throat
  • Serious functional decline due to immobilization during the illness. Consider symptoms such as muscle weakness, loss of condition and fatigue and malnutrition in the elderly. Malnutrition can also occur as a result of loss of smell and taste, which reduces appetite.
  • Post IC syndrome mainly occurs in severe Covid-19 infections requiring admission to the ICU was necessary.
In addition, after a coronavirus infection, a combination of these physical, cognitive and psychological complaints play a role. Other Complaints that occur are pressure ulcers (skin defects due to friction of skin with another material), lung damage (corona obstructive pulmonary disease (COLD)), anxiety and neuromuscular abnormalities.

We have put together two post-covid syndrome blood test packages aimed at these complaints. With the basic post-corona syndrome package we look at the presence of remnants of infection, kidney status and we look at the blood itself to see whether explanations can be found for complaints such as fatigue. With the extensive post-corona syndrome package, we also look at the fitness level of the heart, whether active muscle breakdown is taking place by measuring muscle breakdown products and the nutritional status.

Post-corona syndrome blood test determinations

Fatigue: Hemoglobin, MCV, platelets and iron

With this we test for a common cause of fatigue, namely anemia. Anemia mainly causes fatigue and feeling weak and lethargic. These are complaints that often occur after a coronavirus infection. However, there are many different types of anemia. We make a distinction between macrocytic anemia, normocytic anemia and microcytic anemia by looking at the MCV. The MCV is therefore a way to start looking for the cause. A blood test for anemia therefore always contains the Hb value and the MCV value. If fatigue occurs after an infection with the coronavirus and the cause is reduced hemoglobin, proper and adequate treatment can be provided. Iron is included as standard because this is the most common cause of anemia. A low iron level can be caused by a disturbed diet, such as after infection with Covid. Finally, we also include the platelets (thrombocytes). Research has shown that people who die from Covid-19 have undergone a lot of clotting.

Infection status: BSE

BSE stands for blood sedimentation rate and is a marker for inflammation or infection in the body. As a rule of thumb, the higher the erythrocyte sedimentation rate, the more serious the infection. Do you feel sick after a coronavirus infection? Do you want to know if you are recovering? Then this determination is an adequate determination to quickly gain insight into your disease progression or recovery. With a normal erythrocyte sedimentation rate, acute and / or chronic inflammation can virtually be ruled out.

Kidney function: Creatinine & eGFR

With a post-corona syndrome package we also include kidney function. Kidney function is calculated with the creatinine value. This is a breakdown product of muscles and protein metabolism. In most cases, creatinine is released at a constant rate, unless there are problems with, for example, muscle breakdown and / or muscle building. We see this, for example, after a changed nutritional status, as is the case with a post-covid infection (a Covid infection). We express kidney function in the eGFR, or the estimated GFR, the glomerular filtration ratio. The reason that creatinine can be used for kidney function blood tests is because it passes through the kidneys virtually unchanged. All broken down creatinine is excreted and virtually no creatinine is reabsorbed by the reabsorption system.

Vitamin: Vitamin D

With a post-corona syndrome package we also include vitamin D. Recent research has shown that vitamin D levels in deceased Covid patients have been reduced. By testing for this in time, we can map the vitamin D levels in the blood. This way we can intervene in time with supplements.

When to choose this test?

Choose the post-covid infection blood test package basic when:
  • You want a general blood test screening for post-coronavirus symptoms
  • You have fatigue complaints that could be consistent with anemia due to the coronavirus
  • You have had the coronavirus, but continue to have persistent complaints.


When to test?

The accuracy of the test for Post-Covid Syndroom Basis 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 Post-Covid Syndroom Basis 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 Post-Covid Syndroom Basis 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 Post-Covid Syndroom Basis can be found on the product page. Depending on your insurance and additional packages, you may be reimbursed for these costs for Post-Covid Syndroom Basis. 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 Post-Covid Syndroom Basis 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 Post-Covid Syndroom Basis 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 Post-Covid Syndroom Basis to third parties without permission, not even to your general practitioner without your consent.
The blood test for Post-Covid Syndroom Basis 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 Post-Covid Syndroom Basis 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 Post-Covid Syndroom Basis 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.
