Abstract
Safety test of modified hemoglobin in animals does not always reflect safety in human. We have earlier reported an in-vitro preclinical screening test based on in-vitro complement activation of human plasma In this test, modified hemoglobin is added to human plasma in a test tube. Complement activation is followed by the C3a levels. Since this directly measures the effect of modified hemoglobin on human plasma, this could be an important bridge before clinical use in patients. The use of plasma is suitable for research, development and industrial applications. However, there are many extra steps involved and may not be convenient for population or patient screening on a large scale bases. The present study shows that it is possible to use small sample of whole blood obtained directly from finger pricks and use immediately for analysing complement activation using an ELISA enzyme immunoassay method.
