Sida loo fahmo imtixaanka TGO-AST: Aspartate Aminotransferase

• AST sare maxay ka wadaa
• Sababta cudurka raabiyada
• Marka imtixaanka la dalbado

Baadhitaanka aspartate aminotransferase ama oxalacetic transaminase (AST ama TGO), waa tijaabo dhiig oo la codsaday in lagu baaro nabarrada wax u dhimaya shaqada caadiga ah ee beerka, sida cagaarshow ama cirrhosis, tusaale ahaan.

Oxalacetic transaminase ama aspartate aminotransferase waa enzyme ku jirta beerka waxaana caadi ahaan sare loo qaadaa marka dhaawaca beerka uu yahay mid aad u daba dheeraada, maadaama ay ku badan tahay gudaha unugyada beerka. Si kastaba ha noqotee, enzyme-kan ayaa sidoo kale ku jiri kara wadnaha, waxaana loo isticmaali karaa calaamadeeyaha wadnaha, oo laga yaabo inuu tilmaamo infarction ama ischemia.

Calaamadeeyaha beerka, AST badiyaa waxaa lagu cabbiraa ALT, maadaama laga yaabo inay sare u kacdo xaaladaha kale, iyadoo aan loo cayimin ujeedkan. O Qiimaha tixraaca enzyme wuxuu u dhexeeyaa 5 ilaa 40 U / L dhiigga, kaas oo ku kala duwanaan kara shaybaarka.

AST sare maxay ka wadaa

In kasta oo baaritaanka AST / TGO uusan aheyn mid gaar ah, dhakhtarku wuxuu amri karaa baaritaankaan isaga iyo kuwa kale oo tilmaamaya caafimaadka beerka, sida cabirka gamma-glutamyltransferase (GGT), alkaline phosphatase (ALK) iyo, badanaa ALT / TGP. Waxbadan ka baro imtixaanka ALT.

Kordhinta AST, ama TGO sare, ayaa laga yaabaa inay muujiso:

• Xanuunka loo yaqaan 'pancreatitis Acute';
• Cagaarshow fayras daran;
• Cagaarshowga khamriga;
• Cagaarshowga cagaarshowga;
• Cudurka beerka;
• Kansarka aasaasiga ah ee beerka;
• Dhaawac weyn;
• Isticmaalka daawo sababa dhaawaca beerka;
• Yaraanta Wadnaha;
• Iskeemiya;
• Xuddunta;
• Gubashada;
• Hypoxia;
• Cudurka kaadi-mareenka, sida cholangitis, choledocholithiasis;
• Dhaawaca muruqa iyo hypothyroidism;
• Isticmaalka daawooyinka sida daaweynta heparin, salicylates, opiates, tetracycline, thoracic ama isoniazid

Qiimayaasha ka sarreeya 150 U / L guud ahaan waxay muujinayaan xoogaa dhaawac beerka ah iyo in ka badan 1000 U / L waxay tilmaami karaan cagaarshowga ay sababaan isticmaalka daawooyinka, sida paracetamol, ama hepatitis ischemic, tusaale ahaan. Dhinaca kale, hoos u dhaca qiimaha AST waxay muujin kartaa yaraanta fitamiin B6 marka laga hadlayo dadka u baahan sifaynta.

Sababta cudurka raabiyada

Sababta cudurka loo yaqaan 'Ritis' waxaa loo adeegsadaa dhaqtarka caafimaadka si loo qiimeeyo heerka uu gaarsiisan yahay dhaawaca beerka sidaasna lagu daweeyo daaweynta ugu fiican ee xaaladda. Qiyaastani waxay tixgelin siineysaa qiyamka AST iyo ALT iyo markay ka sarreeyaan 1 waxay muujineysaa dhaawacyo aad u daran, sida cirrhosis ama kansarka beerka, tusaale ahaan. Markay ka yar tahay 1 waxay noqon kartaa calaamadda wejiga daran ee cagaarshowga fayraska, tusaale ahaan.

Marka imtixaanka la dalbado

Tijaabada dhiigga ee TGO / AST waxaa amri kara dhaqtarka markii ay lagama maarmaan tahay in la qiimeeyo caafimaadka beerka, ka dib marka la fiirsado in qofku miisaankiisu culus yahay, dufan ku leeyahay beerka ama ay ka muuqato calaamado ama astaamo ay ka mid yihiin maqaarka maqaarka oo huruud ah, xanuun caloosha dhinaca midig ama xaarka saxaro fudud iyo kaadi madow.

Xaaladaha kale ee ay sidoo kale waxtarka u leedahay in la qiimeeyo enzyme-kan waa ka dib marka la isticmaalo daawooyinka dhaawici kara beerka iyo in la qiimeeyo beerka dadka isticmaala cabbitaanno badan oo aalkolo leh.
