Background Knowledge about CRP rapid test kit

The liver produces a protein known as C-reactive protein (CRP). An increase in CRP is a sign of internal inflammation. Checking your level of C-reactive protein only requires a quick blood test.The CRP rapid test kit (Whole Blood/Serum/Plasma) detects C‐reactive Protein

through visual interpretation of color development on the internal strip. Anti‐CrP

antibodies are immobilized on the test region of the membrane. During testing, the

specimen reacts with anti‐CrP antibodies conjugated to colored particles and precoated on

the sample pad of the test. The mixture then migrates through the membrane by capillary

action, and interacts with reagents on the membrane. If the intensity of the test band is

weaker than reference band (R), it indicates that the CrP level in the specimen is between

10‐30 mg/L. If the intensity of the test band (T) is stronger than the reference band (R), it

indicates that the CrP level is above 30 mg/L. The appearance of control line serves as a

procedural control, indicating that the proper volume of specimen has been added and

membrane wicking has occurred.

Operation Guide

01.Specimen Preparation

1.Use a disposable pipette to transfer 10µL of the specimens and add to the dilution tube

with buffer.

2.Bottom up and down the tube for several time to mix the specimens well.

02.Procedure

1. Remove the test device from its sealed pouch, and place it on a clean, level surface.

Label the device with patient or control identification. For best results, the assay should

be performed within one hour.

2. Add 3 drops of the mixed specimen to the sample. Start the timer.

3. Wait for the colored bands to appear. The result should be read at 5 minutes. Do not

interpret the result after 10 minutes.

Quality Control

 Internal procedural controls are included in the test. Reference band appearing in the

reference regions is considered an internal positive procedural control, confirming

sufficient specimen volume and correct procedural technique.

 External controls are not supplied with this kit. It is recommended that positive and

negative controls be tested as a good laboratory practice to confirm the test procedure

and to verify proper test performance.
