Means person has not had a recent strep. Test values should be less than 100 for children under 5 years of age. The antibodies work against a substance made by the bacteria called streptolysin O.
ASO or antistreptolysin O represents a class of antibodies produced by the immune system. An elevated titer of antibody positive ASO or an ASO titer that is rising means that it is likely that the person tested has had a recent strep infection. However this range may vary depending on the type of technique and protocols used by the lab.
Results will vary by laboratory. Antistreptolysin O ASO is an antibody targeted against streptolysin O a toxic enzyme produced by group A Streptococcus bacteria. If symptoms of rheumatic fever or glomerulonephritis are present an elevated ASO level may be used to help confirm the diagnosis.

The ASO blood test also known as an ASO titer ASO test ASLO lab test and antistreptolysin O antibody titer measures the ASO blood antibody blood levels.
Alternative nameASO ASO AbReference range. Low ASO titer indicates no recent infection. Usually the AST levels in the bloodstream are low.
This test looks for antibodies that your body makes while fighting group A Streptococcus bacteria. In children under the age of 5 the test value should be less than 100. DNase B is produced by group A streptococci and is therefore more specific than the ASO antibody test.
If your results show that you have an elevated ASO value you may have a post-streptococcal complication. Also asked what does a high ASO blood test mean. Generally an ASO test value below 200 is considered normal.
The symptoms of this type of infection typically develop 2-6 weeks after a sore throat or skin infection as the bacteria which caused the infection have moved to a different location in the body. Levels higher than 200 IUml is usually taken as the upper limit of the normal range since this value is rarely exceeded without symptoms indicative of streptococcal infection. A positive test can indicate recent or current group A C and G streptococcal infection eg upper airway infections scarlet fever toxic shock syndrome and may support the diagnosis of post-streptococcal infection complication eg glomerulonephritis and rheumatic fever.
ASO and anti-DNase B are the most common of several antibodies that are produced by the bodys immune system in response to a strep infection with group A StreptococcusThis test measures the amount of ASO in the blood. Higher than normal ASO levels indicate an infection of Streptococcus bacteria. The normal values range of the AST blood test in males is 10 to 40 units per Liter of Serum and in females it is 9 to 32 units per Liter of Serum.
