When to collect your sample
The sample must be collected using the home collection kit* provided in the morning on a Monday - Thursday and returned on the same day.
C-reactive protein (CRP), which is synthesized by the liver, is one of the most sensitive acute-phase markers of inflammation. Elevated CRP often occurs before clinical symptoms, including fever.
CRP elevations are nonspecific but may indicate the presence of an underlying inflammatory infection. Blood CRP is a marker used to detect inflammation in the body. This may indicate the presence of other conditions or infections and can identify deterioration or damage that you may not be aware of.
Who should be tested
A CRP test result can be elevated for many reasons so it is important to talk to your doctor if you are concerned*.
You should be tested if:
You are at risk for chronic inflammatory infections including rheumatoid arthritis, lupus, or vasculitis
You are at risk for Crohn's infection
You are at risk for bowel disorders
You are overweight
*CRP levels may be affected by current infections, recent surgery, inflammatory conditions, and medications that suppress the immune system.
C-reactive Protein (CRP)
C-reactive Protein (CRP) is a plasma protein. It is known as an acute phase protein as its concentration rises when there is inflammation in the body. CRP is produced by the liver, concentrations vary in response to tissue damage or inflammation in the body.
