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.
What causes high ASO levels?
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 the treatment for ASO positive?
Increased levels of ASO titre in the blood could cause damage to the heart and joints. In most cases,
penicillin
is used to treat patients with increased levels of ASO titre.
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 does ASO mean in rheumatoid arthritis?
antistreptolysin-O
(ASO) titre in rheumatoid arthritis. (RA). The mean and the upper ASO values were. first established in a group of normal subjects and in. patients with no history of recent streptococcal.
What is the normal range of ASO?
| Alternative name: ASO, ASO Ab | Reference range: <200IU/mL | Assay range Notes: 200-400IU/mL High normal range Assay range 0-5000 IU/ml | Turnaround time: 5 – 7 days | Analysing laboratory: Immunology The James Cook University Hospital |

Why ASO test is done?
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 will happens if ASO titre is high?
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.
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.
What antibiotics treat rheumatic fever?
Rheumatic fever is preventable by treating strep throat with antibiotics, usually
penicillin
. If a patient is allergic to penicillin, other antibiotics such as erythromycin (Eryc, Ery-Tab, E.E.S, Eryped, PCE) or clindamycin (Cleocin) can be used.
What is the principle of ASO test?
Principle. The detection of anti-streptolysin O antibodies is
based upon the neutralization of the streptolysin O hemolytic activity by antibodies present in the test serum
. The antigen-antibody immunological complexes that are formed are revealed by the addition of a suspension of sheep erythrocytes.
What factors may cause false positive ASO result?
False-positive ASO titers can be caused by
increased levels of serum β-lipoprotein produced in liver disease and by contamination of the serum with Bacillus cereus and Pseudomonas
. ASO titers are elevated in 85 percent of patients with rheumatic fever but may not be elevated in cases involving skin or renal sequelae.
What kind of infection is strep throat?
Strep throat is an
infection of the throat and tonsils caused by a bacteria called group A streptococcus
, also known as Streptococcus pyogenes. This bacteria lives in the nose and throat. You can get the infection from someone who is sick with strep A bacteria or is a carrier of it.
CONCLUSIONS–It is concluded that classic rheumatic fever is now rare, even in patients with arthritis with a high ASO titre. These results support the suggestion that beta haemolytic streptococci may trigger reactive arthritis as well as rheumatic fever.
Can rheumatoid arthritis go away?
Doctor’s Response.
There is no cure for rheumatoid arthritis
, but it can go into remission. Furthermore, treatments are getting better all the time, sometimes to the point a drug and lifestyle regimen can stop the symptoms in their tracks. As a rule, the severity of rheumatoid arthritis waxes and wanes.
How do you permanently treat rheumatoid arthritis?
There is no cure for rheumatoid arthritis
. But clinical studies indicate that remission of symptoms is more likely when treatment begins early with medications known as disease-modifying antirheumatic drugs (DMARDs).
