What does high ASO mean in blood test?
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 does a positive ASO test mean?
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 the treatment of ASO positive?
In most cases, penicillin is used to treat patients with increased levels of ASO titre.
Is ASO treatable?
Unlike the AAV treatment, ASO treatment is not a permanent cure and requires ongoing distribution of the serum to the patient to maintain the reduction of the toxicity. Read more about ASOs in Nature: here.
What is the normal range of ASO?
3.2. Geometric mean titer and upper limits of normal of ASO
| Characteristic | Geometric Mean Titer SD | |
|---|---|---|
| Log Units | IU/ml | |
| 40–49 | 2.2 0.2 | 143.5 |
| 50–59 | 2.1 0.2 | 129.1 |
| 60–70 | 2.0 0.3 | 111.8 |
How do I lower my ASO level?
Corticosteroids and certain antibiotics may reduce ASO antibody levels. This may make it difficult for your doctor to confirm your diagnosis.
Does ASO test require fasting?
This ASO Blood Test is a sensitive test for recent streptococcal infection. Preparation: Fasting for 6 hours required.
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.
Is ASO test confirmatory?
The ASO test does not predict whether complications will occur following a strep infection, nor does it predict the type or severity of the disease. If symptoms of rheumatic fever or glomerulonephritis are present, an elevated ASO level may be used to help confirm the diagnosis.
Is strep A serious?
Caused by the group A streptococcus bacteria, strep throat is an infection that requires prompt treatment, particularly in children over the age of 3. Left untreated, strep throat can lead to kidney inflammation or rheumatic fever, a serious illness that can cause stroke and permanent damage to the heart.
