Evaluation of Automatic Blood Analyzer as Screening Method in Fetomaternal Hemorrhage

Figure 3

Parallel analysis of results obtained by FCM and ABA. (a) Low correlation (Spearman correlation: r = -0.263, p= 0.039, and n = 57) and (b) lack of agreement (bias d = 0.342, standard deviation = 0.6047, and confidence interval = 95% [0.842; 1.526] p = 0.559) were found for the results assessed in blood samples of male adults added with umbilical cord blood at dilutions 1/10, 1/100, 1/1,000, and 1/10,000. (c) No correlation (Spearman correlation: r = -0.316, p = 0.047, n = 40) and (d) agreement (bias d= 0.233, standard deviation = 0.481, and confidence interval = 95% [-0.727; 0.397] p = 0.573) were found for the results assessed in blood samples from puerperal women.
