CRP-Screen® – rapid test for possible infection (C-reactive protein) at home

CRP-Screen® is a quick, user-friendly and CE-marked self-test that has been developed to investigate whether the body may be in an active infection or inflammation phase. The test uses a small drop of capillary blood from the fingertip and gives a result of approx. 5 minutes, with a clear color code that makes it easy to interpret whether the CRP level is low, moderate or very high. CRP (C-reactive protein) is a protein that is mainly produced in the liver and can increase with bacterial infections and inflammatory conditions in the body. The test is a practical screening tool for private individuals who want information before any contact with a doctor, but does not replace a medical assessment.

Health benefits
• 🧪 CRP can provide information about the body's immune response and whether there are signs of ongoing inflammation or infection activity
• 🤒 Semi-quantitative CRP levels can help distinguish between low, moderate and high reaction levels in the body
• 🏥 Less well-known, but useful: CRP-Screen® can be an aid in dialogue with healthcare personnel about symptoms, especially in case of uncertainty about antibiotics or assessment of whether a quick health check might be appropriate

Technical details and specifications
CRP-Screen® is a rapid immunochromatographic test (lateral flow) developed for private use:
• Test type: In vitro immunodiagnostic rapid test for measuring CRP in whole blood
• Analyte: C-reactive protein (CRP)
• Sample: Capillary blood from finger prick
• Sample volume: One drop of blood collected with the supplied plastic pipette
• Test time: Result after approx. 5 minutes (no interpreter after 10 minutes)
• Reading: Colored lines in window (C = control, T = test, as well as center line at higher level)
• Semi-quantitative measurement:
– Low CRP (< 8 mg/L): No T-line
– Moderate CRP (8–40 mg/L): Three lines, weak T line
– High CRP (40–100 mg/L): Three clear lines
– Very high CRP (> 100 mg/L): Strong colored lines, central line may disappear
• Calibration: The test is adapted to WHO reference values
• Use: Suitable for adults who want screening for symptoms such as fever, headache, flu-like sensation or suspected infection
• Storage: In original packaging, dry and at recommended temperature (stated on packaging)
• Disposable test: Each test is used once and discarded after use
• CE-marked rapid test for private use

Label information
Contents per package (typical):
• Test cassette in a sealed bag
• Plastic pipette for blood test
• Diluting liquid in dropper bottle
• Sterile lancet
• Disinfection pad (may vary per package)
• Instructions for use with illustrated test steps

Area of use: Semi-quantitative screening of CRP in whole blood from a finger prick to see if the CRP level is low, moderate or high.
Target group: Adults and families who want to check CRP at home for symptoms of infection or inflammation.
Recommendation: If CRP is positive or high, a doctor should be contacted for assessment.

Brief user guide:
• Wash and disinfect fingertips
• Make a finger prick with a lancet
• Collect a drop of blood in the pipette
• Add the blood to the sample well and add 4 drops of diluent
• Read the result after 5 minutes; no interpreter after 10 minutes
