Fibrinogen: a comparison of an immunoturbidimetric method with four conventional methods

A rapid and simple immunochemical method for fibrinogen determination is described. The method is based on measuring the turbidity caused by antigen-antibody complexes with an enzyme analyser using diluted antiserum as a starting reagent. This immunoturbidimetric method correlates well with the immunodiffusion method and with two of the thrombin methods. Its correlation with the precipitation method according to Low was a little weaker.
