Hematocrit - level yancitshiswa, kwaye ukunyuka izinga

Hematocrit ke ngokomlinganiselo (ipesenti) of erythrocytes ukusuka umthamo wegazi (total). Esi salathisi sibonisa umlinganiselo plasma umthamo kunye ebomvu umthamo legazi. Ngokomzekelo, umntu ogulayo sikwimo bothukile, ukuncipha hematocrit nga ha endleka, lo gama ngenxa ukopha, inani leeseli ezibomvu ngokubanzi nga lincitshiswe. Ngoko ke, asinakusetyenziswa ipesenti, nokuhlola ngesidanga kwegazi kwixesha elizayo emva ukutofelwa igazi okanye ukulahleka igazi.

Hematocrit ukuze enokwehla, ukuba lo kulingwa capture isigulana ukwimo lisalele. Elide compressive tourniquet umthambo ibonakala japan ngobuxoki eziphakamileyo. hematocrit False Low usenokuba ngenxa ukuxutywa igazi. Oku kwenzeka xa isampulu yegazi iyathathwa kwesebe enye, nto leyo kakhulu ngokukhawuleza phambi kokuba ukumnika efakwa.

Ukubekwa ipesenti iiseli ezibomvu zegazi umthamo plasma kunye nesalathisi umbala kunceda kwi izifo ezininzi, ingakumbi ukuba bazalana kutshintsho mpilo. Ndingathi ukuba uhlalutyo ezahlukeneyo kwinqanaba haemoglobin inika ulwazi kangaka. Nesilinganiso zesi salathisi libambisene kunye Isalathisi umbala iiseli ezibomvu zegazi, kwaye hematocrit inika imboniselo enenkcukacha ngakumbi imeko igazi.

Umzekelo, kukho uvavanyo lwegazi kunye ekuncipheni mpilo. Kufuneka kuqatshelwe ukuba loo isalathisi inokuba ngenxa yezizathu ezahlukeneyo. Imiba enze kunye ayoni anemia, nezinye ezinxulumene igazi nobugqi okanye hemolysis eziphakamileyo. Emva kokuchitha uphando, uyakwazi ukuchonga unobangela kwegazi inokuba ilahleko iiseli ezibomvu, kunye neziphumo zayo, ngokulandelelana, - reduced hematocrit. Ukuchaza isalathiso umbala, ukuchonga ukunyhashwa kwi kuyondelelaniswe mpilo. Oku kukuvumela ukuba ubone ukuba yintoni kanye le anaemia: hyperchromic, hypochromic okanye normochromic.

hematocrit eqhelekileyo abadala kunye nabantwana, amadoda kunye nabafazi ezahlukileyo. Ngoko ke, umzekelo, loo nto ithathwa index eziqhelekileyo 33.0-44.5% in amadoda 38.0-49.0% kumabhinqa abaphakathi kweminyaka kominyaka imashumi mabini anethoba.

Hematocrit kuba igazi lubonakala ngokuba nokuphungulwa leyo ebangelwa ukuhla kwenani erythrocytes. Ezi States uxhulumanisa, njengokuba umthetho, kunye nokulahlekelwa igazi okanye hemolysis. Hematocrit lingaba ngaphantsi yaye kwiimeko zivuse ukwanda umthamo wegazi. It ibhiyozelwa ngexesha giperalbunemii lokukhulelwa okanye ityuwa ezisetyenziswa ezininzi.

Lo mboniso nombala zingaphungulwa ukuncipha haemoglobin yokuqaphela. Oku kukhokelela ekuncipheni xi mpilo kwiiseli ezibomvu egazini. Ukuncipha isalathisi umbala ubuye luphawu ukuba imeko apho ukucuthwa ubungakanani erythrocytes lwenzeka (microcytosis). Ukuphucula i index umbala kuvandlakanywa macrocytosis. Kulo mzekelo, ukwanda iseli ebomvu igazi iqulethe ihemoglobin ngakumbi. Le meko uyaqapheleka kwegazi imibala folate, hypothyroidism, ukufumana amachiza cytotoxic.
