The Anti-Streptolysin O (ASO) test is a blood test used to determine the presence of antibodies against the Streptococcus bacteria's streptolysin O toxin. These bacteria can cause strep throat, scarlet fever, and rheumatic fever, among other illnesses.
When the body is exposed to streptococcal bacteria, it generates antibodies against the bacterium's toxins, notably the streptolysin O toxin. The ASO test determines the concentration of these antibodies in the blood.
The ASO test is widely used to aid in the diagnosis of streptococcal infections, especially when symptoms are ambiguous or non-specific. It can also be used to track the evolution of a streptococcal infection and discover complications like rheumatic fever.
An high level of ASO antibodies in the blood might suggest a recent or ongoing streptococcal infection. A negative test result, however, does not completely rule out the potential of a streptococcal infection, since it might take several weeks for the body to build sufficient levels of antibodies.
The ASO test is a straightforward and affordable test that is readily available in most medical laboratories. It is widely regarded as a valuable tool in the diagnosis and treatment of streptococcal infections.
Here, the test is performed in a Genrui analyzer by the " Nephelometry" method. The result is analyzed on the basis of light scattering at a specific wavelength from the turbidity of a solution.
