Ogaanshaha Tooska ah ee Ka-hortagga Fayraska

Hababkan taxanaha ah waa imtixaano iyadoo la adeegsanayo antigen-ka fayraska gaarka ah si loo ogaado unugyada difaaca jirka ee serumka bukaanka, oo ay ku jiraan ogaanshaha unugyada difaaca IgM iyo cabirka unugyada difaaca IgG.Unugyada difaaca jirka ee IgM waxay baaba'aan dhowr toddobaad gudahood, halka IgG-ga difaacayaasha ay sii jiraan sanado badan.Samaynta ogaanshaha infekshanka fayraska waxaa lagu dhammeeyaa serologically iyadoo la muujinayo kor u kaca titer antibody ee fayraska ama muujinta unugyada kahortaga fayraska ee fasalka IgM.Siyaabaha loo isticmaalo waxaa ka mid ah baaritaanka dhexdhexaadinta (Nt), baaritaanka dhammaystirka hagaajinta (CF), baaritaanka hemagglutination inhibition (HI), iyo baaritaanka immunofluorescence (IF), hemagglutination dadban, iyo difaac difaac.

Ogaanshaha Tooska ah ee Ka-hortagga Fayraska

A. Qiimaynta Dhexdhexaadinta

Inta lagu jiro infekshanka ama dhaqanka unuggu, fayrasku waxa uu joojin karaa unuggiisa gaarka ah waxana uu lumin karaa caabuqa, nooca antibody-ga waxaa lagu qeexaa sida antibody-ka dhexdhexaadka ah.Qiimaynta dhexdhexaadinta waa in lagu ogaado antibody-ka ka-hortagga ee serumka bukaanka.

B. Baadhitaannada Hagaajinta dhammaystirka

Qiimaynta hagaajinta dhamaystirka waxa loo isticmaali karaa in lagu raadiyo joogitaanka antibody gaar ah ama antigen ee ku jira serumka bukaanka.Tijaabadu waxay isticmaashaa unugyada dhiigga cas ee idaha (SRBC), antibody-ka-hortagga SRBC iyo dhammaystirka, oo ay weheliso antigen gaar ah (haddii aad raadinayso antibody ee serum) ama antibody gaar ah (haddii aad raadinayso antigen ee serum).

C. Baadhitaannada Joojinta Hemagglutination

Haddii fiirsiga fayraska ee muunadku uu sarreeyo, marka muunadda lagu qaso RBC-yada, xijaabka fayrasyada iyo RBC-yada ayaa la samayn doona.Dhacdadan waxa loo yaqaan hemagglutination.Haddii unugyada difaaca jirka ee ka soo horjeeda hemagglutinins ay jiraan, hemaglutination waa laga hortagayaa.Inta lagu jiro baaritaanka ka-hortagga hemagglutination, dareeraha serial ee serum ayaa lagu qasi karaa cadad la og yahay oo fayras ah.Ka dib markii la isku qurxiyo, RBCs ayaa lagu daraa, isku dar ah ayaa loo daayaa inay fadhiiso dhowr saacadood.Haddii hemagglutination la joojiyo, pellet ee RBCs ayaa ka sameysmaya gunta hoose ee tuubada.Haddii hemaglutination aan la joojin, filim khafiif ah ayaa la sameeyay.
