Anti-Streptolysin O Antibody ASO - This test is a sensitive test for recent streptococcal infection. In an infected individual streptolysin O acts as a protein antigen and the patient mounts an antibody response. Besides leukocytosis and increased levels of inflammatory markers the patients laboratory results showed an extremely high D-dimer concentration and an increased antistreptolysin O ASO titer.
Anti-streptolysin O ASO or ASLO is the antibody made against streptolysin O an immunogenic oxygen-labile streptococcal hemolytic exotoxin produced by most strains of group A and many strains of groups C and G Streptococcus bacteria. ASO titer is a test that measures these antibodies in the blood serum. ASO levels do not rise with cutaneous infections.
