TEST PRINCIPLE
PocTell® CRP Rapid Test Device is an immunochromatographic test, based on two specific antibodies against human CRP. The concentration-dependent formation of test lines allows a rapid semiquantitative determination of CRP in whole blood samples, plasma and serum.
The diluted sample is added into the sample well of the device. The sample now moves through the test Device from bottom to top. If the test sample contains CRP, it attaches to the first anti-CRP antibody which is conjugated with a red gold colloidal for color marking. The red CRP antibody-gold complex, together with the sample liquid, diffuses through the membrane that is pre dispensed with lines of different amounts of the second anti-CRP antibody. The CRP-antibody-gold complex is immobilized by the antibodies coated on the membrane leading to the formation of red lines. The number of lines depends on the CRP concentration in the sample. The more CRP is contained in the sample, the more red lines become visible.
The control line serves as a procedural control and indicates that sufficient volume of specimen has been added and membrane wicking has occurred.
DIRECTIONS FOR USE
Allow the test, specimen, buffer and/or controls to reach room temperature (15-30°C) prior to testing.
Bring tests, specimens, buffer, and/or controls to room temperature (15-30°C) before use.
1.Remove the test 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.Use a dropper to transfer 10 µL of the specimens and add to the dilution tube with buffer.
3.Bottom up and down the tube for several time to mix the specimens well.
4.Add 2-3 drops of diluted specimen (About 80µL-120µL) above to the specimen well and start the timer.
5.Wait for the colored bands to appear. The result should be read at 5 minutes. Do not interpret the result after 10 minutes..
