QuikRead go wrCRP
QuikRead go wrCRP is a fast and easy to use test for quantitative determination of C-reactive protein (CRP) values in whole blood, serum, and plasma with the QuikRead go instrument. The test gives wide range CRP results within minutes and speeds up the path for correct diagnosis.
Accurate measurement of C-reactive protein (CRP) can be critical in the management of a patient with symptoms of an infection. The QuikRead go wrCRP test helps to identify patients who benefit from antibiotics and it is valuable in monitoring the treatment outcome. The easy to use QuikRead go wrCRP test can be used near the patient and it provides immediate wrCRP result.
QuikRead go wrCRP has wide measuring range, which covers for both high sensitive and conventional CRP tests. Modest increase in CRP levels within the high sensitivity range of 1-5 mg/l may indicate low level inflammation and aid in cardiovascular risk assessment1.
QuikRead go wrCRP is an efficient tool for point of care settings to guide the treatment decisions of healthcare professionals.

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
I would like to start using the QuikRead go wrCRP tests. Which instrument software version I need on my QuikRead go instrument?
You should have the version 7.5.1.
I have updated my QuikRead go instrument into version 7.5.1 to start using the QuikRead go wrCRP test. However, now I noticed I have still some QuikRead go CRP kits in fridge. Can I use these kits still after the software update?
Yes, in addition to the QuikRead go wrCRP tests, you can use the QuikRead go CRP and QuikRead go CRP+Hb kits with the QuikRead go instrument software version 7.5.1.
I accidentally left a QuikRead go wrCRP kit at room temperature for a weekend. Can I still use it?
Yes, you can use the kit. The unopened kit 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) for 3 months. The reagent caps for 6 months. See more information in the package insert.
What happens if I accidentally use the 20 µl capillaries with the QuikRead go wrCRP test?
It is important to use only the 10 µl capillaries with orange stripe, which are inside the QuikRead go wrCRP test kit. The 20 µl capillaries have a blue stripe and are to be used with QuikRead go CRP test only. The instrument measures the haematocrit value and above the upper limit (75%), it will not give results. If you dispense twice the amount of sample, the instrument thinks the haematocrit value is double what it actually is. The HCT correction is able to correct only those sample results, which have hematocrit below 37.5%.
