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

Frequently asked questions
Is it possible to use QuikRead CRP kits for QuikRead go?
No, for QuikRead go you can only use QuikRead go CRP kits. QuikRead go requires a bar code on the cuvette, whereas QuikRead 101 uses a magnetic card.
The QuikRead go instrument gives me a result of > 200 mg/l, but I would like to get an exact CRP result. Is it possible?
When using plasma/serum samples you can dilute the sample with 0.9 % NaCl before adding it to the cuvette. The recommended dilution is 1+3. Remember to multiply the result by 4.
I accidentally left a QuikRead go CRP kit at room temperature for a weekend. Can I still use it?
Yes, you can use the kit. The kit can be stored at room temperature (18 - 25 °C) for one month. If it is used at room temperature during daily working hours (7.5 hours) and stored at 2 - 8 °C after finishing work, the kit will remain stable for 3 months.
Can I use controls other than QuikRead CRP Controls with the QuikRead go CRP kit?
Yes, you can use other commercially available controls. The acceptable control limits must be defined with the precision results gained with the QuikRead go instrument. The blanking process might not succeed if you use a control which contains artificial red blood cells because they might not haemolyse normally.
Why do QuikRead go CRP kit components have different expiration dates and why does the kit have shorter shelf life than some of the components?
The kit components have different chemical properties. Therefore, the shelf lives of the components are different. The kit has it’s own expiration date which is the same as the expiration date of the first expiring component.
