From: Optimization of the arginase activity assay micromethod for macrophages and sera
Use of the non-parametric Mann-Whitney test for intergroup comparisons between activated macrophages vs. control macrophages and HAT sera versus control sera. For the comparison of the two methods, the Kruskal-Wallis test is used for determination of arginase activity in sera from controls (n = 10) and patients with human African trypanosomiasis (n = 10) from the Bouenza focus in the Republic of Congo
