I am new on this site . My fiancé was feeling un-well and had quite extensive blood tests. Everything was ok or within normal parameters, however his Derived Fibrinogen level was 5.75 g/L (2.0 - 5.3) Above high reference limit. His serum prostate specific antigen level was 0.31 ug/L (0.0 - 3.0), which appears normal.
I know nothing about Fibrinogen in fact I have never heard of it. Could somebody offer me a bit of guidance here please?
