Product Description

CRP-test - indicates infection or inflammation in the body

The Quicktest CRP test measures CRP concentration. CRP, which is produced in the liver, is a specific protein in the blood that can be used to detect infection or inflammation in the body. Previously, something called "sänkan" was often used, which was actually a Swedish invention. Today, a so-called CRP test is used instead. CRP is an abbreviation for C-Reactive Protein and is an important part of the immune system. Simply put, the concentration of CRP increases during infection or inflammation. Therefore, measuring this value is a safe and reliable way to detect infection or inflammation at an early stage.

In healthy individuals, the CRP concentration is less than 8 mg/L, while the concentration level can be higher than 100 mg/L in case of severe infection or inflammatory process. Intermediate levels, i.e. from 8 to 100 mg/L, often indicate a virus or bacterial infection that needs further investigation by a doctor.

Why test CRP?

Within healthcare, CRP testing is common, usually performed when there is suspicion of infection or inflammation in the body. CRP tests can be used to detect serious illnesses that may be caused by bacteria. The CRP value can also be measured to check for chronic inflammation in the body. This applies, for example, to certain diseases in the joints and intestines. The CRP value normally increases when the disease is in an active phase. In healthcare, CRP is taken after surgeries to rule out infection. Elevated CRP levels indicate an increased risk of future cardiovascular disease. However, it is important to remember that levels >10 mg/L are usually detected during an ongoing or recently undergone infection such as a cold.

Frequently Asked Questions

How does the test work?

The test has different thresholds, and a predetermined number of lines appear on the test cassette for each CRP level. This way, you get a clear result. The result is read/interpreted by interpreting the intensity of the lines that appear in the test window. The different CPR levels are:

  • CRP level below 8 mg/l
  • CRP level between 8 to 40 mg/l
  • CRP level between 40 to 100mg/l
  • CRP level above 100 mg/l

How safe and reliable are your self-tests compared to tests done at a healthcare center?

Our tests are reliable, but it is important to understand how the tests work and how they differ from laboratory tests. Simply put, it works like this:

There are different types of self-tests, but regardless of the type of test, a body fluid is required; some require blood, some urine, saliva, and some secretions from, for example, the vagina. When the body fluid comes into contact with the test, a reaction occurs, and a result is shown - positive or negative. A test that shows a positive or negative result is called a qualitative test, so you get a yes or no. The tests are "pre-programmed" with a so-called threshold value; if the result is above or below a predetermined threshold value, the test shows positive. The threshold value is determined by WHO (World Health Organization).

A laboratory test provides a quantitative answer, i.e., you get a value. Our tests instead provide a positive or negative result based on a threshold value established by WHO. A laboratory provides an exact value, e.g., 18.5 mg/l of CRP. In this case, our test would have shown 2 lines, which means positive (you should contact a doctor). Laboratories provide an exact value, while our tests provide a positive or negative result.

Can the test be used for diagnosis?

No. Our tests are not used for diagnosis; they are used to provide an indication. It is always a doctor who makes the diagnosis, which is often done after various tests, medical history, and clinical examinations.

The Doctor Says...

In a self-test, and particularly in the case of a CRP test, the primary question is usually whether you are healthy or sick. CRP was previously called "the sedimentation rate". A high CRP value is often associated with an infection. It is a very common marker in healthcare, especially in acute care. A high CRP value indicates that something is not right and usually leads to a closer investigation by a doctor into the underlying cause.

Rita
Many more people should discover self-testing. It is usually difficult to get me to the doctor at all, we usually solve most things ourselves, also not so easy always to get into the health care centre Had real stomach pains for several days, they eased a little but did not get well The daughter-in-law forced your CRP test on me. When I did your self-test, the result showed a catastrophically high level. the highest! Called the health centre and asked for an appointment with the doctor, wanted to check if the self-test had shown the right result, still had pain and was terribly tired. They refused to take a blood test and let me see the doctor, was basically declared an idiot when I had your test that was still visible if also a little blurred, even the explanation of the test. Got the feeling that they had decided not to let anyone in to protect themselves, when I objected they told me to go home and wait a few days. When I came out of their little room at the back, my son was waiting for me. He was furious and rushed into the health centre and demanded a doctor immediately. The doctor was on site after 10 minutes, now the health centre's CRP showed a value of 220, it was immediately sent to a University Hospital for an MRI and new tests, in a few hours the CRP value had gone up to 294 and I was admitted. Everything was about a severe inflammation of the pancreas, caused by gallstones Now the bile is removed even though it took almost a week before they got my CRP values below 100 to dare to operate. / Rita

Perfect to have at home, have used on the children when I suspected pneumonia. Minus that you do not deliver within 12h in Stockholm, want it immediately. / Lisa
