About C-reactive protein (CRP)
CRP aids clinical management of patients with infections or inflammatory conditions
C-reactive protein (CRP) is an acute-phase plasma protein present in healthy individuals at low concentrations. The median CRP level of healthy people is usually < 0.8 mg/l1 but the concentration increases fast during bacterial infection, being able to go up to hundreds of mg/l. Bacterial infections and inflammatory conditions stimulate the production of CRP in the liver. From the initial stimulus, CRP levels become detectable in 4-6 hours and peak in 36-48 hours2,3. CRP production is proportional to the intensity of infection and inflammation. Therefore, it is useful in the evaluation of disease severity. In bacterial infections, CRP may increase relatively high, above 100 mg/l. Viral and self-limiting bacterial infections cause only a minor elevation or not elevation at all. In inflammatory conditions, CRP levels may increase to moderate level, usually being between 10-40 mg/l. When the patient starts responding to treatment, the immune system overcomes the pathogen itself, or the inflammatory stimulus starts settling, CRP levels decrease rapidly back to normal with a half-life of 19h1,2.
Accurate and precise CRP point of care testing is helpful in the clinical management of patients with infection and in optimizing antibiotic prescribing. The short analytical time and a small sample volume of CRP point of care tests offer a substantial benefit compared to the laboratory CRP test. When used together with the clinical examination of a patient, QuikRead go CRP tests are excellent tools in the following situations:
- differentiation of bacterial and viral infections
- decreasing diagnostic uncertainty and guiding appropriate antibiotic prescribing in acute infections4,5
- evaluation, monitoring, and prediction of the infection course, inflammation and treatment response6-8
- ruling out severe bacterial infection9

Antibiotics and CRP
Antibiotics are a cornerstone of the management of bacterial infections. 80 - 90% of antibiotics are prescribed in primary care, and up to 80% of these are used to treat acute respiratory tract infections1. It is estimated that approximately 50% of all antibiotic prescriptions are unnecessary2. Although most of both upper and lower respiratory tract infections are self-limiting and caused by viruses, antibiotics are frequently used to treat these conditions. Unnecessary and inappropriate use of antibiotics favours the emergence and spread of resistant bacteria. Antibiotic resistance is a major public health concern, which could cause harm to a large number of patients worldwide if infections are no longer susceptible to common medicines used to treat them. Therefore, antibiotics should be used with caution and only when necessary3.
The use of antibiotics in primary care varies considerably between countries, which is unlikely to be caused by differences in the frequency of bacterial infections. There is a clear correlation between the use of antibiotics and the emergence of antibiotic resistance4-6. As stated by the World Health Organization (WHO)3, restricting an inappropriate and excessive antibiotic use is important to slow down or even reverse the development of antibiotic resistance.
The QuikRead go CRP test helps healthcare professionals to identify those patients who need - and particularly those who do not need - antibiotic therapy. It is also important to know whether the antibiotics will affect the course of the illness7,8. QuikRead go CRP is useful for following up the effect of treatment. With accurate information, patients can be more easily reassured that symptomatic treatment will be sufficient. On the other hand, a high QuikRead go CRP reading would suggest a bacterial infection requiring antibiotic treatment.

Frequently asked questions
I would like to start using the QuikRead go easy CRP test. Which instrument software version I need on my QuikRead go instrument?
You should have the version 7.6.2. or newer. This software is suitable also for all of the other test kits that we provide.
Can I store QuikRead go easy CRP kits at room temperature?
Yes, the unopened kits can be stored at cool or room temperature (2…25 ºC) until the expiry date marked on the kit label. After the first opening of the kit components, the cuvettes can be kept at room temperature (18…25 ºC) for 3 months. The reagent caps for 6 months. The sample collectors can be stored at 2…25 ºC until the expiry date of the kit. See more information in the package insert.
Why does the sample collector not disturb the measurement?
The sample collector stays in the cuvette during the whole measurement. The accuracy of the measurement is not affected because the sample collector does not hit the light path of the instrument.
Which sampling device is suitable for the QuikRead go easy CRP test?
QuikRead go Sample Collectors 10µl, which are included in the QuikRead go easy CRP test kit, must be used for sampling and adding the sample or control into the QuikRead go easy CRP cuvettes. Other sampling devices or capillaries are not suitable for this test.
