What happens if ASO titre is high?
ASO antibodies will remain detectable in your blood for several months after an infection. If you have elevated levels of ASO antibodies, it means that you have probably had a recent strep infection. If your levels are taken again later and are higher, it also means you’ve probably had a recent strep infection.
What is ASO titer positive?
Because it takes time for the number of antibodies to increase in your blood after you are infected, you may need to repeat the ASO titer 2 weeks after your first blood sample. A positive result means that antibodies have been found. This means that you may have had a recent strep infection.
What is ASO titre test for?
Antistreptolysin O (ASO) titer is a blood test to measure antibodies against streptolysin O, a substance produced by group A streptococcus bacteria. Antibodies are proteins our bodies produce when they detect harmful substances, such as bacteria.
What is ASO disease?
Acute rheumatic fever is characterised by fever, sore throat and migratory joint pains and may also manifest with heart, brain or skin symptoms. Antistreptococcal antibodies are specific antibodies to streptococcal antigens (proteins) and indicate true infection with Streptococcus.
What is considered high ASO level?
Generally, an ASO test value below 200 is considered normal. In children under the age of 5, the test value should be less than 100. Results will vary by laboratory. If your results show that you have an elevated ASO value, you may have a post-streptococcal complication.
What is the normal range of ASO?
What is strep infection in blood?
Streptococcal toxic shock syndrome (STSS) is a rare, but serious bacterial infection. STSS can develop very quickly into low blood pressure, multiple organ failure, and even death. Good wound care, hand hygiene, and cough etiquette are important for preventing this serious and often deadly disease.
Why did ASO titre increase?
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. ASO titers that are initially high and then decline suggest that an infection has occurred and may be resolving.
Can ASO be cured?
In most cases, penicillin is used to treat patients with increased levels of ASO titre.
