Have you been to see your doctor recently and he told you that you need to be tested for a C-reactive protein? If your answer was yes, then you might have had a surgery lately and he needs to check for an infection. After any type of surgery, the level of CRP will rise after two to six hours. But the third day after your surgery, it should go back to normal. But if this level does not go back down, then there may be a chance that an infection has begun.
This test will track diseases and infections that can cause inflammation in your body. Some of these diseases can be: a disease of the immune system like lupus or cancer of the lymph nodes, also called lymphoma. Rheumatoid arthritis which is swelling of the tissues in the joints can also cause an inflammation in your body. A bone infection and any bleeding or swelling of the intestines are also on the list of disease to keep an eye out for.
This test is done by wrapping a band made of elastic around your upper arm. This will stop the flow of blood and cause a vein to become easier to see. Just like giving a blood sample. Blood is removed, the needle is taken out and a bandage is put on the needle site. There are conditions that will effect the outcome of this test and your doctor should tell you about them. You should not have just exercised before coming in to have blood taken for this test. There are some medications that will interfere with this test and they are: hormone replacement therapy, birth control pills, aspirin, corticosteriods and cholesterol lowering medications. If you are female and you have a intrauterine device in place, it could be a cause for bad test results or if you are pregnant or if you are overweight. If your test shows that you have a high level of C-reactive protein then it is likely that you could develop an infection after your surgery. This test can also tell your doctor how you will respond to a treatment for cancer.This is a very reliable test to measure general levels of inflammation that can be in your body although it can not tell your doctor where in your body the inflammation is or what has caused it to develop. There are other tests that can do that.
