Correlation of a clot-weight and radial immunodiffusion method for estimation of plasma fibrinogen concentration
A clot-weight and radial immunodiffusion method for estimating fibrinogen concentration were compared using plasma from 58 pregnant women and diabetic patients. The two methods gave a correlation coefficient, r = 0.53 (p less than 0.005). There was no significant variation between the mean fibrinogen concentrations as determined by both methods. The coefficient of variation for the clot-weight and immunodiffusion methods were 1.54% and 2.9%, respectively. It is concluded that the clot-weight method is more readily applicable than the radial immunodiffusion method to fibrinogen measurements, especially in patients when rapid results are required.
