Transfusions generally do not cause significant changes in C-reactive protein (CRP) levels. Post-transfusion CRP increases were small and not clinically significant, with larger rises likely due to infection.

Area of Science:

  • Clinical Chemistry
  • Hematology
  • Immunology

Background:

  • C-reactive protein (CRP) is a marker of inflammation.
  • Transfusion reactions can sometimes cause inflammatory responses.

Purpose of the Study:

  • To investigate the effect of blood transfusions on serum CRP levels.
  • To determine if transfusions cause a clinically significant inflammatory response.

Main Methods:

  • Prospective study analyzing serum CRP levels.
  • 18 transfusional episodes assessed using fluorescence polarization immunoassay.
  • Patients selected with stable CRP for two days prior to transfusion.

Main Results:

  • Small CRP increases observed post-transfusion in 55.6% of cases.

  • No statistically significant difference between pre- and post-transfusion CRP values.
  • Increases were not clinically significant; large rises (>100 mg/l) were rare and likely infection-related.

    • Conclusions:

    • Blood transfusions do not appear to cause significant elevations in serum CRP.
    • Observed CRP changes are generally minor and not indicative of transfusion-related inflammation.
    • Underlying conditions, such as infection, are more probable causes for substantial CRP increases post-transfusion.
