The s-ALCAM values were significantly elevated in the blood serum of PAC patients (n = 116, mean 29.4 ng/ml, standard deviation (SD) 1.1 ng/ml, p<0.001) compared to CP patients (n = 115, mean 18.2 ng/ml, SD 1.0 ng/ml) and healthy blood donors (n = 128, mean 21.1 ng/ml, SD 0.7 ng/ml, Figure 3A). The gene discussed is ALCAM; the disease is gonorrhea.
