ASO analysis
ANALYSIS (ASO) is an abbreviation of anti-streptolysin O, which is some antibodies formed in the body when the body is infected with a bacteria called streptococci Group A. No, this analysis is done by taking a blood sample and examining it, and the normal ratio of (ASO) in the blood is less than 200 IU / ml. If the body is streptococci Group A, ASO titre), and diseases that cause an increase in the level (ASO), we mention the following:
- Rheumatic fever, where it can reach about 800 IU / ml. The ASO analysis is one of the most common tests for rheumatic fever, in addition to an analysis called ESR.
- Other diseases that cause an increase in ASO are scarlet red.
- As well as cases of bacterial endocarditis, which are caused by streptococci.
This may be explained by the fact that the antibody (ASO) which is formed in the body may remain in the body and blood for a long time and may be up to several months after the injury of the person, That is, there may be a person who has been infected with strept (Group A) and after treatment, specifically after two or three months has performed an analysis (ASO) found to be high, hence we conclude that it is not possible to diagnose the disease only by this analysis, Perform some other analysis accompanying him in addition to the symptoms that appear on the injured.
Causes of elevated level (ASO) in the blood
The reasons for the increase in the rate (ASO) in the blood are as follows:
- Inflammation of the heart called acute heart murmur caused by Streptococcus.
- Other causes include renal ulcer infections due to sepsis in the streptococcus, where the level is between (500 – 5000).
- The occurrence of parasitic neuropsychological disorders associated with streptococcus.
- Other causes of reactive arthritis.
- The occurrence of so-called rheumatic fever (rheumatic fever).
- Infection with nodal infestations occurs where the level is moderately high.
