Acute kidney failure is one of the most dangerous consequences of a coronavirus infection. It’s no wonder that more and more patients are asking: What can I do to protect my kidneys? Above all, it is important to regularly monitor kidney function using means such as urine analysis. The Reactif urine tests from the medical-technology company nal von minden, which is based in Germany, determine up to 14 health and kidney-related parameters within a matter of seconds. The test serves doctors and home-users as a diagnostic aid for the monitoring of a range of health-related parameters.
“For people who are – or have been – infected with coronavirus, checking the kidneys regularly can really bring peace of mind,” says Roland Mei?ner, CEO at nal von minden GmbH. "A urine test is a good way of identifying potential changes in kidney function", says Mei?ner. “A urine test provides patients with extra surety. It is an excellent method of monitoring. The earlier potential kidney damage is recognised, the better it can be treated.”
The Reactif urine test looks at a variety of parameters for the purpose of monitoring overall health, kidney function included. Tests for professional use can test up to 14 parameters, whereas those for private use test up to 11 parameters (see info box), one of which is protein. The presence of small amounts of protein in urine is normal and no cause for concern. However, large amounts can be an indicator of kidney damage. Another important parameter is white blood cells (leukocytes): Increased levels in urine can signify a kidney infection.
The Reactif urine test can be carried out by doctors in a GP practice or by individuals at home, as it is also designed for self-testing. The test procedure is quick and easy: Simply dip the test strip in urine, then remove it. Depending on the parameter, results will be available within 60 – 120 seconds. Place the test strip next to the reference colour chart and compare the colour panels.
“In the event of deviation from normal levels, the affected individual should contact their doctor for further diagnosis,” advises Mei?ner. The nal von minden CEO does not see the urine test as an alternative to a visit to your GP, but rather as a means of providing additional protection for patients who were – or are – infected with coronavirus. “Parameters tested by your GP can be checked over in order to shed light on any potential irregularities.”
Above all, Mei?ner hopes that monitoring kidney levels can help to prevent deterioration or even death. As several studies (see below) have already shown, COVID-19 affects not only the lungs but also the kidneys. Even in mild cases, it is common to see changes in the urine. In severe cases, the kidneys can fail completely and this can often be deadly. Mei?ner explains that “the urine test is an early warning system for severe COVID cases.”
Kidney failure. The kidneys fulfil an important function in the body. They act as a point of detoxification, filtering out harmful substances from the body. They also produce the urine that is excreted through the bladder. The problem is that kidney disease is often identified too late. In the early stages there are hardly any symptoms. It is only in the later stages that patients experience, for example, nausea, tiredness and a dull ache in the kidney region. If the kidney tissue becomes diseased, the kidneys can only work to a limited extent. The final stage, kidney failure, is life-threatening. The kidneys no longer function and cannot excrete harmful substances, leaving the body in danger of being poisoned.
