The ASO analysis is an analysis of the amount of antibodies in the blood. These antibodies are the body's antibodies to a particular type of bacterium and its scientific name is Streptococci Group A. Thus, it is possible to know whether the body is infected with these bacteria , And thus can diagnose many diseases caused by these bacteria.
And normal blood antibodies: less than 200 IU per blood.
Causes of high blood antibodies:
We also mentioned that any infection with Streptococci Group A bacteria cause an increase in the proportion of antibodies to ASO titre body, and the most common diseases that can increase this ratio are:
- Rheumatic fever, which can reach 800 IU per blood, and ASO is one of the most important tests for the diagnosis of rheumatic fever in addition to the analysis of the speed of blood deposition ESR.
2 - Scarlet fever. - In the case of Bacterial endocarditis caused by streptococci.
=================
It is important to note that if a person is infected with bovine bacteria and is fully recovered, the proportion of ASO antibodies that were previously (during the disease) remains for a long time in his blood, and may reach this period for several months after infection.
