C-reactive protein test (hs-crp)


High-sensitivity C-reactive protein (hs-CRP), is an acute phase (stress) protein that indicates systematic inflammation in response to infection or injury. In adults, CRP is an important marker in cardiovascular disease and rheumatoid arthritis. An elevation suggests a strong link between these conditions and bacterial or viral infection. In children, a study has documented elevated antibodies to Chlamydia in autism and high levels of C-reactive protein have been associated with exposure to Chlamydia pneumoniae. CRP shows promise as a useful marker of the inflammatory process in children and adults with autism.


Serum: 1 mL of serum in a gold-topped SST or royal blue-topped no additive tube.
