Basics
C-Reactive Protein (CRP) is an acute-phase protein that is produced mainly by the liver and increases in concentration as a result of injury, infection and inflammation. Although it is not a specific marker for a particular disorder, CRP is currently used as a generic diagnostic indicator of infection and inflammation and to monitor patients’ reactions to treatment and post-operative recovery.
CRP levels in the blood are high during bacterial infections and low during viral infections. For this reason, the dosage of of C-reactive protein can be a useful tool to define the origin of an inflammatory state. Monitoring CRP levels over time helps to define the effectiveness of a therapy and evaluate a patient’s healing process. CRP levels in the blood reach their peak concentration between 24 and 48 hours after the onset of the first symptoms of infection/inflammation, and then begin to decrease as the infection clears/inflammation subsides.

HOW DOES THE C-REACTIVE PROTEIN TEST WORK?
The test detects the presence of CRP in human whole blood samples using specific antibodies and colloidal gold particles embedded in the test strip.
WHEN CAN THE TEST BE USED?
The C-REACTIVE PROTEIN TEST may be used in the case of infection or inflammation symptoms such as fever, headache or weakness, or to monitor the healing process following surgery and minor injuries. The test can also be used to monitor the effectiveness of a therapeutic treatment and can be performed at any time of the day.
CAN THE RESULT BE INCORRECT?
The result is correct as long as the instructions are carefully followed and the test is stored under the conditions listed in the „Precautions“ section. However, the result may not be correct if: the device comes into contact with other liquids before being used, if the amount of blood and/or diluent is not enough, if the number of drops dispensed in the well is incorrect or if the reading times are not strictly followed. The supplied plastic pipette allows users to be sure they have collected the right amount of blood.
HOW DO I INTERPRET THE TEST IF THE COLOUR AND INTENSITY OF THE TEST AND CONTROL BANDS ARE DIFFERENT?
The colour and the intensity of the lines are not important for the interpretation of the result. Refer to the „Interpretation of results“ section and images to correctly evaluate the result.
IS THE RESULT RELIABLE IF READ AFTER 6 MINUTES?
No. The test must be read 5 minutes after the procedure is completed and no later than 6 minutes from this time. Results read after 6 minutes may not be correct.
WHAT SHOULD I DO IF THE RESULT IS POSITIVE?
If the result is positive and the CRP is higher than 10 mg/l, refer to the “Result interpretation” section and contact your doctor as soon as possible, because antibiotic treatment may be required.
WHAT SHOULD I DO IF THE RESULT IS NEGATIVE?
A negative result means that the concentration of CRP is below 10 mg/l, which means that there is neither viral nor bacterial infection in progress. If symptoms persist, seek medical advice.
HOW ACCURATE IS THE C-REACTIVE PROTEIN TEST?
The C-REACTIVE PROTEIN Test showed high concordance with analytical reference methods, with 97% accuracy in distinguishing between normal (< 10 mg/l) and abnormal values.
