An anti-streptolysin O enzyme inhibition test was performed on the serum of a 10-year-old female patient with the following results: no hemolysis in the 1:10,1:20,1:40,and 1:80 tubes; hemolysis in the 1:160,1:320,and 1:640 tubes.What conclusion can you draw from these results?

The titer is the highest dilution at which there is no hemolysis, which is 1:80 in this case. This result is within the normal range, indicating the patient does not have an elevated anti-streptolysin O titer that would suggest a recent streptococcal infection, such as those leading to rheumatic fever or glomerulonephritis.
