QuikRead go wrCRP
QuikRead go wrCRP is a fast and an 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.

Generally
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
A wide range CRP test allows the extension of CRP values from conventional use to testing e.g neonatal sepsis1 as well as to predict disease severity in COPD2 and aid in cardiovascular risk assessment3. Room temperature storage for unopened kit and small sample volume ease the everyday work flow.
QuikRead go wrCRP is an efficient tool for point-of-care settings to guide the treatment decisions of healthcare professionals.

Specific features of CRP (C-reactive protein)
- normally present in very low concentrations in the blood of healthy people; 99% have levels of <10 mg/l 1 and 90 % have levels < 3 mg/l2.
- after birth concentrations are very low (0,1 mg/l) and there is a physiological rise during the first days of life (to approx. 2 mg/l)3
- uncomplicated viral infections mostly induce (with some exceptions) a very modest elevation or none at all1
- in bacterial infections, concentrations increase markedly1
- elevated concentrations can be detected within 6 - 12 h after onset of an inflammatory stimulus, reaching maximum within 24 - 48 h4, 5
- rise in concentrations corresponds to severity of infection1
- concentrations fall rapidly when the patient responds to antibiotic treatment1
- normalisation of the concentration may indicate that the duration of the treatment has been sufficient and the treatment can be discontinued1, 6, 7
- in a big part of septic neonates the concentrations are below 6 mg/l 8, 9, 10

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 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%.
