QuikRead go CRP for the USA
The QuikRead go CRP test is an immunoturbidimetric assay for the in vitro quantitative determination of C-reactive protein (CRP) in K2-EDTA and lithium heparin whole blood, K2-EDTA and lithium heparin plasma, and in serum samples. The test is carried out by means of the QuikRead go instrument.
Measurement of C-reactive protein aids in the evaluation of injury to body tissues, and infection and inflammatory disorders. The instrument and assay are for use by trained professionals in the clinical laboratory.
QuikRead go CRP provides you with
- Test time is two minutes
- Supports STAT sample analysis
- Minimum hands-on-time
- Supports flexible processes in the laboratory
- Substantially equivalent to two clinical chemistry analyzers
Ease of use
- Easy testing procedure and intuitive user interface
- Maintenance-free instrument
Test results should never be used alone, without a complete clinical evaluation. For professional use. Not for point-of-care. Read more: QuikRead go CRP for the USA > Risks and limitations of the procedure

C-reactive protein, CRP
Infections, tissue injuries, and inflammatory disorders may be accompanied by a non-specific elevation of the CRP level in the patient’s blood. The rise in CRP levels is rapid, and increased levels can be detected within 6–12 hours of the onset of the inflammatory process.1 In acute inflammatory processes the CRP levels can reach approximately 20‒500 mg/L.2, 3
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 infections.1, 4−7 The advantages of measuring CRP lie in it being a sensitive, early, and reliable reflector of the acute-phase response. It can also be used for accurate monitoring of the patient’s condition and response to therapy. However, the rise in CRP level is non-specific.

Use of QC materials is recommended for each day of testing, in accordance with federal, state, and/or local regulations or accreditation requirements. The QuikRead go CRP Control set (145217) is recommended to be used with the QuikRead go CRP test.
The QuikRead go CRP tests are factory-calibrated. The QuikRead go CRP Verification Set (145216) should be used for verification of the calibration in line with CLIA regulations.
Risks and limitations of the procedure
Assay procedures other than those specified in these instructions may yield questionable results. Some substances may interfere with the test results; please see Section “Interference” below.
CRP results should never be used alone, without a complete clinical evaluation. Intraindividual variations in CRP are significant and should be taken into account – e.g., by means of serial measurements – in interpretation of the values.
The QuikRead go CRP test is not intended for use as high sensitivity CRP or cardiac CRP.
|Interferent||No interference found up |
|Vitamin C||35 mg/L|
|Rheumatoid factors (RF)||525 IU/mL|
|Anticoagulants (Li-heparin or EDTA)||No interference|
|Hemoglobin (plasma and serum)||20 g/L|
Most heterophilic or anti-sheep antibodies in the samples do not
interfere with the test, because the assay antibodies lack the Fc part.
In rare cases, interference by IgM myeloma protein has been observed.

Frequently asked questions
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, 64-77 °F) for one month. If it is used at room temperature during daily working hours (7.5 hours) and stored at 2 - 8 °C (36-46 °F) after finishing work, the kit will remain stable for 3 months.
The QuikRead go instrument gives me a result of > 150 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.
