A viscometric method of measuring plasma fibrinogen concentration.

A viscometric method of measuring plasma fibrinogen concentrations.

A technique based on deducing the viscosity of serum from that of plasma was compared with the commonly used Clauss method. The two methods correlated closely (r = 0.914). The reproducibility of the viscometric method was slightly poorer than the Clauss technique at low fibrinogen concentrations, equal to that at medium fibrinogen concentrations, and marginally better at high concentrations.

A rapid "side-room" method for the determination of plasma fibrinogen concentration as fibrin.

A method is proposed for the rapid estimation of plasma fibrinogen concentration. The technique depends on the increase of optical density occurring when plasma clots. A kit is described which obviates the use of laboratory apparatus, so that the test may be performed in the ward side-room if a small centrifuge can be provided.A calibration curve has been prepared for use with commercial opacit...

Improved method for measuring fibrinogen in plasma, with use of a plasmin inhibitor.

We describe a modified procedure for quantitating plasma fibrinogen by use of the thrombin-clottable protein technique. The method is accurate and requires a0out 30 min to complete. During its formation and isolation, the clot is protected from the degradative action of plasmin by an inhibitor, epsilon-aminocaproic acid.

Influence of fibrinogen concentration upon plasma prothrombin time.

A simple gravimetric method for estimation of plasma fibrinogen.

The study was undertaken to evaluate a new method of estimating plasma fibrinogen levels, gravimetrically using calcium chloride in albino rats. The results were compared with the standard method in which thrombin was used as clotting agent and were found to be statistically not significant. Advantages of using calcium chloride instead of thrombin have been discussed.
