The C-reactive protein test in its highly sensitive form can be used to screen people who are at risk of developing cardiac and vascular disease. High levels of hs-CRP have found to be indicative of risk of development of arterial diseases, heart attack and stroke despite low levels of lipids in the body. The people who are recommended to take CRP test are smokers, individual suffering from hypertension, diabetics, people with family history and aged individuals.
C-reactive protein test is also used to check for inflammation in the body. However, the presence of CRP in the bloodstream cannot determine the exact cause nor identify the exact location of the inflammation. But the test together with a thorough evaluation of the presented C-reactive protein high symptoms as well as other necessary lab tests, can help correctly identify the type of inflammatory condition such as rheumatoid arthritis, inflammatory bowel disease, lymphoma, osteomyelitis etc. and also setup an effective C-reactive protein treatment plan.
How to Prepare for a CRP Test
Depending upon your physician, you may or may not be asked to fast prior to the CRP test, or high sensitive CRP test if you’re being checked for heart disease risks. If you’re told to fast, do not eat or drink water at least 9 to 12 hours prior to the test.
It is also recommended that you tell your physician if you’re taking any medication, since one of them could affect the test results.
A blood sample will be taken from you to check for CRP level. If CRP test for heart disease is performed, you will be checked routinely to make sure that the level stays low and, at the same time, assess if the current treatment is efficient or not.
What the Results Mean
The C-reactive protein normal range should be lower than 1 mg/L.
Checking the CRP blood test results on your own is easy to do. If your CRP level falls below the normal level, then your test is okay. A high CRP level, on the other hand, means that there is inflammation in the body. If you were checked for CRP high sensitivity test and it revealed a high level, then you have a higher risk for cardiovascular diseases. The higher the value, the higher the risks for heart attack.
Common CRP Test Questions
Can the presence of hs-CRP predict the development of a heart disease?
Although HSCRP test is typically given to assess heart disease risks, it is not conclusive since CRP is just an inflammation marker. Other tests like a full lipid profile and tests to check for cardiac risk markers will be given to assess the condition and provide a more definitive diagnosis. Of note, CRP level may also be elevated in other diseases like diabetes and cancer.
I have been given a full lipid profile test, but not an hs-CRP. Is that okay?
High sensitive CRP test is not a part of a regular blood workup, like a full lipid profile test. Depending on the symptoms you presented during your doctor’s visit, this test may or may not be performed.
Can you explain what a regular CRP is, compared to an HS CRP lab test?
Both tests are performed to check for the presence of CRP protein. However, hs-CRP test is typically given to people to assess their risks for the development of a heart disease. On the other hand, regular CRP C-Reactive Protein test is given to patients who exhibit signs and symptoms of a chronic infection or inflammation.
