What happens if ASO titre is positive?

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 ASO blood test used for?

Definition. 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 does a high ASO blood test mean?

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 normal range of ASO titre?

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 treatment for ASO positive?

In most cases, penicillin is used to treat patients with increased levels of ASO titre.

Quels sont les anticorps de l’ASLO?

Ces infections donnent lieu à la production d’anticorps, en particulier de type ASLO (Anti-StreptoLysine O).

Quels sont les symptômes d’une élévation des ASLO?

Une élévation des ASLO s’observe en cas de : Rhumatisme articulaire aigu (RAA) ; Glomérulonéphrite aigue streptococcique (maladie du rein) ; Scarlatine ; Erythème noueux : Angines streptococciques (inconstamment) : Dans certains myélomes.

Quel est le taux de l’ASLO?

Titre > 200 U ASLO /ml : significatif d’une infection streptococcique Les ASLO apparaissent environ 10 jours après une infection aiguë, maximum vers le 30 ème jour, taux résiduel après 6 mois. Un deuxième dosage après traitement antibiotique peut permettre d’apprécier l’efficacité du traitement (diminution des taux).

Pourquoi le taux d’ASLO augmente-t-il?

Si les résultats montrent que le taux ASLO augmente, l’infection est probablement récente. Si les taux diminuent, cela signifie qu’une infection s’est produite et qu’elle est probablement guérie.
