Zithini iimvavanyo zeplatelet?

Iiplatelets, ezikwabizwa ngokuba zii-thrombocyte, ziiseli ezincinci zegazi ezibalulekileyo ekunqandeni igazi. Ukuvalwa kwenkqubo kukunceda uyeke ukopha emva kokwenzakala. Zimbini iintlobo zovavanyo lweplatelet: uvavanyo lweplatelet count kunye novavanyo lomsebenzi weplatelet.

Uvavanyo lweplatelet count Linganisa inani leeplatelets egazini lakho. Inani leplatelet elingaphantsi kwesiqhelo libizwa ngokuba yitrombocytopenia. Le meko inokubangela ukuba wophe kakhulu emva kokusikwa okanye okunye ukwenzakala okubangela ukopha. Inani eliphezulu leplatelet libizwa ngokuba yi-thrombocytosis. Oku kunokwenza igazi lakho lijiye ngaphezulu kunokuba ufuna njalo. Ukuqina kwegazi kunokuba yingozi kuba kunokuthintela ukuhamba kwegazi.

Uvavanyo lomsebenzi wePlatelet jonga ubungakanani beeplatelets zakho zokwenza amahlwili. Uvavanyo lomsebenzi wePlatelet lubandakanya:

• Ixesha lokuvala. Olu vavanyo lilinganisela ixesha elithathayo kwiiplatelets kwisampulu yegazi ukucoca umngxunya omncinci kwityhubhu encinci. Inceda isikrini kwiimpawu ezahlukeneyo zeplatelet.
• Viscoelastometry. Olu vavanyo lilinganisa amandla egazi njengoko lisenzeka. Ihlwili legazi kufuneka lomelele liyeke ukopha.
• Iplatelet aggregometry. Eli liqela leemvavanyo ezisetyenziselwa ukulinganisa ukuba iiplatelets zidibana njani kakuhle (zizonke).
• Lumiaggregometry. Olu vavanyo lilinganisa inani lokukhanya okuvelisiweyo xa izinto ezithile zongezwa kwisampulu yegazi. Inokukunceda ukubonisa ukuba kukho iziphene kwiiplatelets.
• Ukuhamba kwecytometry. Olu luvavanyo olusebenzisa ii-lasers ukukhangela iiproteni kumphezulu weeplatelets. Inokukunceda ekufumaniseni ukuphazamiseka kweplatelet. Olu luvavanyo olukhethekileyo. Ifumaneka kuphela kwizibhedlele neelabhoratri ezithile.
• Ixesha lokopha. Olu vavanyo lilinganisa inani lexesha lokuphuma kwegazi ukuze liyeke emva kokusikwa okuncinci kwingalo yangaphambili. Kwakudla ngokusetyenziselwa ukukhenketha kwiintlobo ezahlukeneyo zeengxaki zeplatelet. Ngoku, olunye uvavanyo lweplatelet lusetyenziswa rhoqo. Iimvavanyo ezintsha zibonelela ngeziphumo ezinokuthenjwa.

Amanye amagama: ukubalwa kweplatelet, ukubala kwe-thrombocyte, uvavanyo lweplatelet function, umsebenzi weplatelet assay

Zenzelwe ntoni?

Inani leplatelet lihlala lisetyenziselwa ukubeka esweni okanye ukufumanisa imeko ezibangela ukopha kakhulu okanye ukubamba kakhulu. Inani leplatelet linokubandakanywa kubalo olupheleleyo lwegazi, uvavanyo oluhlala lusenziwa njengenxalenye yokuhlolwa rhoqo.

Uvavanyo lomsebenzi wePlatelet unokusetyenziselwa:

• Nceda ufumane isifo esithile seplatelet
• Jonga ukusebenza kweplatelet ngexesha lotyando oluntsonkothileyo, olunje ngokudlula kwentliziyo kunye nonyango lotyando. Ezi ntlobo zeenkqubo zinomngcipheko okhulayo wokopha.
• Jonga izigulana ngaphambi kotyando, ukuba zinembali yobuqu okanye yosapho yokuphazamiseka kokopha
• Ukujonga abantu abathatha abacoci gazi. La mayeza anokunikezelwa ukunciphisa ukujiya kwabantu abasemngciphekweni wokuhlaselwa sisifo sentliziyo okanye ukubetha.

Kutheni ndifuna uvavanyo lweplatelet?

Unokufuna ukubalwa kweplatelet kunye / okanye ukuvavanywa kokusebenza kweplatelet ukuba uneempawu zokuba neeplatelets ezimbalwa okanye ezininzi kakhulu.

Iimpawu zeeplatelets ezimbalwa zibandakanya:

• Ukopha ixesha elide emva kokunqunyulwa okanye ukwenzakala okuncinci
• Iimpumlo
• Ukugruzuka okungachazwanga
• Khomba ubomvu obomvu esikhumbeni, esaziwa ngokuba yi-petechiae
• Amabala amfiliba eluswini, awaziwa ngokuba yi-purpura. Oku kunokubangelwa kukopha phantsi kolusu.
• Ixesha elinzima kunye / okanye elide lokuya esikhathini

Iimpawu zeeplatelets ezininzi zibandakanya:

• Ubungqongqo bezandla neenyawo
• Intloko ebuhlungu
• Ukuba nesiyezi
• Ubuthathaka

Unokufuna uvavanyo lweplatelet ukuba uyi:

• Ukwenza utyando oluntsonkothileyo
• Ukuthatha amayeza ukunciphisa amahlwili

Kwenzeka ntoni ngexesha lovavanyo lweplatelet?

Uninzi lweemvavanyo zeplatelet lwenziwa kwisampulu yegazi.

Ngexesha lovavanyo, ingcali yokhathalelo lwempilo iyakuthatha isampulu yegazi kwimithambo engalweni yakho, kusetyenziswa inaliti encinci. Emva kokuba inaliti ifakiwe, inani elincinci legazi liya kuqokelelwa kwityhubhu yovavanyo okanye igutyana. Unokuziva uluma kancinci xa inaliti ingena okanye iphuma. Oku kuhlala kuthatha imizuzu engaphantsi kwesihlanu.

Ngaba kuya kufuneka ndenze nantoni na ukulungiselela uvavanyo?

Awudingi naluphi na ulungiselelo olukhethekileyo kuvavanyo lweplatelet count

Ukuba ufumana uvavanyo lweplatelet, kusenokufuneka uyeke ukuthatha amayeza athile, njengeasprini kunye nebuprofen, phambi kovavanyo lwakho. Umboneleli wakho wezempilo uya kukwazisa ukuba ngaba kukho nayiphi na imiyalelo ekhethekileyo ekufuneka uyilandele.

Ngaba bukhona ubungozi kuvavanyo?

Mncinci kakhulu umngcipheko wokuvavanywa kwegazi. Unokuba nentlungu encinci okanye ukrakra kwindawo apho inaliti yafakwa khona, kodwa uninzi lweempawu zihamba ngokukhawuleza.

Zithetha ntoni iziphumo?

Ukuba iziphumo zakho zibonisa inani eliphantsi kuneplatelet count (thrombocytopenia), inokubonisa:

• Umhlaza ochaphazela igazi, njengeleukemia okanye i-lymphoma
• Usulelo lwentsholongwane, njenge-mononucleosis, i-hepatitis, okanye imasisi
• Isifo somzimba. Esi sisifo esenza ukuba umzimba uhlasele izicwili zawo ezisempilweni, ezinokubandakanya iiplatelets.
• Usulelo okanye ukonakala kumongo wethambo
• Isibindi
• Ukusilela kweVitamin B12
• I-Gestational thrombocytopenia, imeko eqhelekileyo, kodwa ephantsi, eseplatelet echaphazela abasetyhini abakhulelweyo. Ayaziwa ngokwenza nawuphi na umonakalo kumama okanye kusana lwakhe olungekazalwa. Ihlala iphucuka ngokwayo ngexesha lokukhulelwa okanye emva kokuzalwa.

Ukuba iziphumo zakho zibonisa ukubala okuphezulu kweplatelet (thrombocytosis) ephezulu, inokubonisa:

• Iindidi ezithile zomhlaza, ezinje ngomhlaza wemiphunga okanye umhlaza webele
• Ukunqongophala kwegazi
• Ukudumba kwesifo
• Irheumatoid Arthritis
• Usulelo lwentsholongwane okanye ibhaktiriya

Ukuba iziphumo zomsebenzi weplatelet bezingaqhelekanga, oko kunokuthetha ukuba unelifa okanye ufumene isifo seplatelet. Ukuphazamiseka okuzuzwe njengelifa kudluliselwa kusapho lwakho. Iimeko zikhona xa kuzalwa, kodwa usenokungabi nazimpawu de ube umdala. Ukuphazamiseka okufumanekayo akukho xa kuzalwa. Zingabangelwa zizinye izifo, amayeza, okanye ukubonakaliswa kwindalo esingqongileyo. Ngamanye amaxesha unobangela awaziwa.

Ukuphazamiseka kweplatelet okulindelweyo kubandakanya:

• Isifo seVon Willebrand, isifo semfuza esinciphisa ukuveliswa kweeplatelets okanye sibangele ukuba iiplatelets zisebenze kancinci. Ingabangela ukopha okungaphezulu.
• I-thrombasthenia kaGlanzmann, isifo esichaphazela amandla eeplatelets 'okuhlangana
• Isifo sikaBernard-Soulier, esinye isifo esichaphazela amandla eeplatelets 'okuhlangana ndawonye
• Isifo samachibi okugcina, imeko echaphazela amandla eeplatelets okukhupha izinto ezinceda iiplatelets zidibane

Ukuphazamiseka kweplatelet okufumanekileyo kunokubangelwa zizifo ezinganyangekiyo ezinje:

• Ukungaphumeleli kwezintso
• Iindidi ezithile zegazi
• I-Myelodysplastic syndrome (MDS), isifo somongo wethambo

Ngaba ikhona enye into endifuna ukuyazi malunga novavanyo lomsebenzi weplatelet?

Uvavanyo lweplatelet ngamanye amaxesha lwenziwa kunye novavanyo olunye okanye nangaphezulu kulandelayo:

• Uvavanyo lwegazi lwe-MPV, olulinganisa ubungakanani beeplatelets zakho
• Ixesha lovavanyo lwe-thromboplastin (PTT), elilinganisa ixesha elithathayo ukuze igazi lijiye
• Ixesha leprothrombin kunye novavanyo lwe-INR, olujonga ukubanakho komzimba ukwenza amahlwili egazi
