QuikRead go easy CRP

The QuikRead go easy CRP is an easy to use and reliable point-of-care test, which gives quantitative CRP test results within 2 minutes. The unique one-step Sample Collector used with the QuikRead go easy CRP minimizes hands-on steps and enables fast and easy CRP testing.


Quantitative measurement of CRP concentration has been reported to be a sensitive indicator of the efficacy of antimicrobial therapy and the course of bacterial infections, as well as an effective tool in controlling and monitoring postoperative infections1-5. Modestly elevated CRP values have been shown to be clinically relevant e.g. in neonatal sepsis6-8, and conditions that include systemic inflammation (such as COPD9-11 and Rheumatoid arthritis11,13).

QuikRead go easy CRP provides you with

Unique one-step Sample Collector

  • Fast and easy sample collection improves workflow
  • Convenient for the patient

Room temperature storage up to +25 °C

  • Easy to store in the health care unit
  • Enables immediate use, no need to warm up the reagents

Reliable CRP results in minutes

  • CRP measuring range from whole blood  is 1−200 mg/l and 1−120 mg/l with serum or plasma samples

QuikRead go multianalyte point-of-care system

  • Portable and fully automatic point-of-care system
  • Bi-directional connectivity to most HIS and LIS systems

Test results should never be used alone, without a complete clinical evaluation.

QuikRead go easy CRP is not registered in the USA.

Controls and related products

Regular use of QuikRead CRP Controls is recommended.

The Controls available are:

  • Ultrasensitive CRP Control, with a concentration of approx. 2-3 mg/l 
  • QuikRead go wrCRP Control, with a concentration of approx. 30 mg/l
  • QuikRead go wrCRP Control High, with a concentration of approx. 80 mg/l
  • QuikRead go CRP Control Low, with a concentration of approx. 2,5 mg/l
  • QuikRead go CRP Control, with a concentration of approx. 25 mg/l
  • QuikRead go CRP Control High, with a concentration of approx. 75 mg/l

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.
  • 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 h3, 4
  • 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 discontinued1,5,6
  • in a big part of septic neonates the concentrations are below 6 mg/l 7,8,9

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. 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 10 µl, which are included in the QuikRead go easy 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.
