La streptolysine O ndi chinthu chopangidwa ndi mabakiteriya a streptococcal (Gulu A) akapatsira thupi.

Kukhalapo kwa streptolysin kumayambitsa kuyankha kwa chitetezo cha mthupi komanso kupanga ma anti-streptolysin antibodies, omwe cholinga chake ndi kusokoneza chinthucho.

Ma antibodies amenewa amatchedwa antistreptolysins O (ASLO). 

Mayesowa amatha kuzindikira ma antibodies a antistreptolysin O m'magazi, omwe amachitira umboni kukhalapo kwa matenda a streptococcal (monga angina kapena pharyngitis, rheumatic fever).

Kuyesedwa sikumayikidwa nthawi zonse kuti azindikire streptococcal pharyngitis (kuyesa kofulumira kwa smear yapakhosi kumagwiritsidwa ntchito pa izi). Amasungidwa kwa milandu ina yomwe amaganiziridwa kuti ndi matenda a streptococcal, monga rheumatic fever kapena pachimake glomerulonephritis (matenda a impso).

Ndi zotsatira zotani zomwe tingayembekezere kuchokera pakuwunika kwa antistrptolysin O?

Kuwunika ikuchitika ndi yosavuta kuyesa magazi, mu labotale yosanthula zamankhwala.

Palibe kukonzekera kwapadera. Komabe, zitha kulimbikitsidwa kuti mutenge chitsanzo chachiwiri patatha milungu iwiri mpaka 2 kuti muyese kusinthika kwa mulingo wa antibody.

Nthawi zambiri, mulingo wa antistreptolysin O uyenera kukhala wosakwana 200 U / ml mwa ana ndi 400 U / ml mwa akulu.

Ngati zotsatira zake ndi zoipa (ndiko kuti, mkati mwazovomerezeka), zikutanthauza kuti wodwalayo sanatenge kachilombo ka streptococcus. Komabe, mu nthawi ya a matenda streptococci, kukwera kodziwika kwa ASLO nthawi zambiri sikudziwika mpaka masabata 1 mpaka 3 mutadwala. Choncho, zingakhale zothandiza kubwereza kuyesa ngati zizindikiro zikupitirira.

Ngati mulingo wa ASLO ndi wapamwamba kwambiri, sikokwanira kunena mosakayikira kuti pali matenda a strep, koma mwayi ndi wapamwamba. Kuti atsimikizire izi, mlingo uyenera kusonyeza kuwonjezeka koonekera bwino (kuchulukitsa ndi zinayi za titre) pa zitsanzo ziwiri zotalikirana masiku khumi ndi asanu.

Phindu la ma antibodies amenewa limabwerera mwakale pasanathe miyezi 6 mutadwala.
