Ukuhlolwa kwe-Alkaline Phosphatase

I-Alkaline phosphatase (ALP) isebenza njenge-enzyme ebalulekile emzimbeni womuntu, idlala indima ebalulekile ekusebenzeni kwesibindi nempilo yamathambo. Lokhu kuhlola okulula kodwa okunamandla kusiza odokotela bathole futhi bahlonze izinkinga ezithinta isibindi, amathambo, nezinye izimiso ezibalulekile zomzimba. Ukuqonda amazinga e-alkaline phosphatase kusiza odokotela benze izinqumo ezinolwazi mayelana nezinhlelo zokwelapha futhi baqaphe ukusebenza kokunakekelwa kwezokwelapha okuqhubekayo.

Kuyini ukuhlolwa kwe-Alkaline Phosphatase?

Ukuhlolwa kwe-alkaline phosphatase (ALP) ukuhlolwa kwegazi okulinganisa ukugcwala kwe-enzyme ye-ALP egazini. Leli thuluzi lokuxilonga lisiza odokotela ukuthi bahlole ukusebenza kwesibindi nempilo yamathambo ngokuhlaziywa kwesampula yegazi okulula. 

Odokotela banga-oda izinhlobo ezimbili ezihlukene zokuhlolwa kwe-ALP:

• Ukuhlolwa Okujwayelekile kwe-ALP: Inguqulo evame kakhulu, evamise ukufakwa kumaphaneli e-comprehensive metabolic (CMP) noma ukuhlolwa kokusebenza kwesibindi
• Ukuhlolwa kwe-ALP isoenzyme: Ukuhlolwa okukhethekile okukhomba izinhlobo ezithile ze-ALP ngokusekelwe kumsuka wazo emzimbeni.

I-enzyme ye-ALP ikhona kuwo wonke umzimba, ngokugxila okubalulekile esibindini, emathanjeni, placenta, amathumbu, nezinso. Lapho kwenzeka ukulimala kwezicubu noma ukuphazamiseka kulezi zindawo, amazinga e-ALP egazini angase ashintshe, okwenza lokhu kuhlola kube yigugu ekutholeni izinkinga zempilo ezingaba khona.

Kufanele Uthole Nini Ukuhlolwa Kwe-Alkaline Phosphatase?

Odokotela batusa ukuhlolwa kwe-alk phosphatase ezimeni ezithile ezithile, okuyenza ibe ithuluzi elibalulekile lokunakekelwa kokuvimbela nokuxilonga. Ukuhlolwa kuvame ukufakwa njengengxenye yokuhlolwa kwezempilo okujwayelekile, ikakhulukazi ngaphakathi kwamaphaneli e-metabolic (CMP) namaphaneli esibindi.

Odokotela bavame uku-oda ukuhlolwa kwe-alkaline phosphatase kulezi zimo eziyinhloko:
