Hematocrit - ezingeni kuyehla, kanti i likhuphuke

Hematocrit lokhu ingxenye (iphesenti) zama-erythrocyte egazini ivolumu (inani). Kulolu hlu ibonisa isilinganiso zomthamo futhi abomvu egazi ivolumu. Ngokwesibonelo, isiguli ngubani beshaqekile, kwehle hematocrit ngeke ayithathe indawo, kuyilapho ngenxa ukopha, inani abomvu egazi ashaye jikelele zingancishiswa. Ngakho-ke, iphesenti ingasetshenziswa yini, ekuhloleni ngezinga igazi esikhathini esizayo esiseduze ngemva kokumpontshelwa igazi noma ukopha.

Hematocrit liphansi futhi, uma ku Assay bamba isiguli usesimweni lisalele. Isikhathi eside compressive tourniquet umthambo kungabonakala nasemkhakheni yi amanga aphakeme. Amanga hematocrit okuphansi kungase futhi kube ngenxa dilution wegazi. Lokhu kwenzeka uma isampula yegazi ethathwa esitho efanayo, okuyinto kwaba ngempela ngokushesha ngaphambi ukumnika emthanjeni.

Ukunqunywa iphesenti egazi abomvu zomthamo kanye inkomba umbala kusiza izifo eziningi, ikakhulukazi uma zihlobene izinguquko e-hemoglobin. Mangithi ukuthi ukuhlaziywa ehlukile hemoglobin inikeza ukwaziswa okuningi kangaka. Nesilinganiso le nkomba ihambisana inkomba umbala kwamangqamuzana egazi abomvu, futhi hematocrit ihlinzeka ukubuka okunemininingwane isimo igazi.

Ngokwesibonelo, kukhona ukuhlolwa igazi nge -hemoglobin encishisiwe. Kufanele kuqashelwe ukuthi i-enjalo Inkomba kungenzeka kubangelwa yezizathu ezihlukahlukene. Izinto angase enze futhi yensimbi ukuntula kwegazi, futhi anaemia ezihambisana ngegazi nemimoya noma hemolysis aphakeme. Ngemva kokuchitha ucwaningo olubanzi, ungakwazi ukuthola ukuthi kubangelwa yini igazi kungaba ukulahlekelwa kwamangqamuzana egazi abomvu, nomphumela waso, ngokulandelana, - a hematocrit encishisiwe. Kuchazwa index umbala, ukukhomba ukwephulwa synthesis elithwala umoya-mpilo. Lokhu kukuvumela ukuba unqume ukuthi yini ngempela anaemia: hyperchromic, hypochromic noma normochromic.

hematocrit Jwayelekile e abadala kanye nezingane, amadoda nabesifazane zihlukile. Ngakho, ngokwesibonelo, kubhekwa Inkomba evamile 33.0-44.5% kubantu besilisa nakubantu 38.0-49.0% abesifazane abaneminyaka ephakathi kwengu-engamashumi amabili amabili nesishiyagalolunye.

Hematocrit for anaemia elinesimo esincishisiwe okuyinto zibangelwa ukwehla kwenani erythrocyte. Lezi iinkhathi axhunyiwe, njengoba umthetho, ne ukopha noma hemolysis. Hematocrit liphansi futhi ezimweni okuchukuluza ukwanda umthamo wegazi. It lugujwa ngesikhathi sokukhulelwa giperalbunemii noma usawoti esetshenziswa inqwaba.

Isibonisi umbala kungancipha nokungawuvivinyi ngokwanele-hemoglobin zamagama. Lokhu kuholela ukwehla lokuhlushwa elithwala umoya-mpilo kwamangqamuzana egazi abomvu. Encishisiwe umbala Inkomba kubuye sici for isimo lapho nokuncipha Usayizi erythrocyte kwenzeka (microcytosis). Ukuthuthukisa Inkomba umbala ebonwe macrocytosis. Kulokhu, kukhuphuke ingqamuzana legazi elibomvu futhi iqukethe-hemoglobin ngaphezulu. Lesi senzakalo ebonwe folate ukuntula kwegazi, i-hypothyroidism, ethola izidakamizwa cytotoxic.
