COVID-19 Spotlight: Human C Reactive Protein

C Reactive Protein (also known as C-RP; PTX1; Pentraxin-Related; Pentraxin 1) is a protein involved in the activation, amplification, and regulation of the complement system.² CRP is often also involved in defense related functions including identifying foreign pathogens and removal of damaged host cells.² As a result, levels of CRP are often elevated at the onset of infection, or immediately after tissue injury.² High levels of CRP have also been found in patients infected with COVID-19.³ 

Recent studies have looked at a variety of different biomarkers in relation to COVID-19, and several laboratory abnormalities associated with poor prognosis with COVID-19.⁴ Among these, the concentration of CRP in patients has been shown to be an important marker for infection outcome.⁵ Patients who die from a COVID-19 infection have been seen to maintain a high level of CRP.⁵ As a result, CRP is a possible predictor of prognosis for COVID-19 infection and can be a test for quickly identifying patients who may need enhanced monitoring for respiratory distress or dysfunction to avoid the worsening of their condition.⁶ 

Reddot Biotech is pleased to offer a Human C Reactive Protein ELISA kit in both our traditional and Ready-To-Use formats. Our Human CRP kits have a nanogram range (detection range 0.156-10ng/mL; sensitivity 0.057ng/mL) and are suitable for use with a wide variety of different sample types. For more information and to see the product manual, visit our product pages for RDR-CRP-Hu and RD-CRP-Hu. For any other questions, please feel free to contact us.
