D Uvavanyo lweDimer

intshayelelo

Uvavanyo lwe-D-dimer luvavanyo lwegazi lokuxilonga olulinganisa ubukho be-D-dimer, iqhekeza elifunyenwe egazini emva kokuba ihlwili legazi liphuka. Sisixhobo esibalulekileyo esisetyenziswa ngababoneleli bezempilo ukuvavanya ukuphazamiseka kwe-clotting kunye nokunceda ukuxilonga iimeko ezifana ne-deep vein thrombosis (DVT), i-pulmonary embolism (PE), kunye nokusabalalisa i-intravascular coagulation (DIC). Nangona amanqanaba e-D-dimer anokuphakama kwezinye iimeko, isebenza njengento ebalulekileyo xa idibene neempawu zekliniki kunye nezinye iimvavanyo zokuqinisekisa okanye ukulawula iingxaki ezithile zempilo.

Yintoni uvavanyo lwe-D-Dimer?

Uvavanyo lwe-D-dimer luvavanyo lwegazi olulinganisa inqanaba le-D-dimer egazini lakho. I-D-dimer yiqhekeza elincinci leprotheni eliveliswa xa ihlwili legazi liphuka. Umzimba wenza amahlwili egazi njengenxalenye yenkqubo yawo yokuphilisa yendalo ukuyeka ukopha, kodwa ngamanye amaxesha amahlwili anokwenza ngokungafanelekanga, okukhokelela kwiimeko ezinokuba yingozi. Xa ihlwili legazi liqhekeka, i-D-dimer ikhutshwa egazini.

Kuxilongo lwezonyango, uvavanyo lwe-D-dimer lusetyenziselwa ukunceda ukulawula okanye ukuqinisekisa ubukho beemeko ezinxulumene ne-clotting engaqhelekanga, kuquka:

• I-Deep Vein Thrombosis (DVT)
• I-Pulmonary Embolism (PE)
• Ukusasazwa kwe-Intravascular Coagulation (DIC)

Amanqanaba e-D-dimer aphakamileyo ayixilonga imeko ethile kodwa asetyenziselwa ukubonisa ukuba uphando olongezelelweyo luyafuneka. Izinga eliqhelekileyo okanye eliphantsi le-D-dimer ngokubanzi libonisa ukuba isigulane asinalo ukuphazamiseka okusebenzayo kwe-clotting, kodwa amanqanaba angaqhelekanga angabonisa iindidi zeenkxalabo zempilo.

Lusebenza njani uvavanyo lwe-D-Dimer?

Uvavanyo lwe-D-dimer lwenziwa ngokuzoba isampuli yegazi kumthambo osengalweni yakho. Emva koko igazi licutshungulwa kwilabhoratri apho amanqanaba e-D-dimer alinganiswa kusetyenziswa izixhobo ezikhethekileyo. Uvavanyo lulinganisa uxinzelelo lwe-D-dimer egazini lakho kwiinanograms ngemililitha nganye (ng/mL) okanye iimicrograms ilitha nganye (µg/L).

Amanqanaba aphezulu e-D-dimer angacebisa ukuba i-clot ikhona okanye ukuba i-clotting iyenzeka kwindawo ethile emzimbeni, kodwa ayikwazi ukukhomba ngokuthe ngqo indawo okanye imbangela yehlwili. Ngoko ke, uvavanyo luhlala lusetyenziswa ngokubambisana nezinye iindlela zokuxilonga, ezifana novavanyo lwe-imaging (CT scans okanye i-ultrasounds), ukuqinisekisa ukuxilongwa.

Ukusetyenziswa kovavanyo lwe-D-Dimer

Uvavanyo lwe-D-dimer lusetyenziswa ikakhulu ukunceda ababoneleli bezempilo ukuba bavavanye ubukho beengxaki zokujiyisa, kubandakanya:

• Ukuxilongwa kwe-Deep Vein Thrombosis (DVT): I-DVT yenzeka xa ihlwili legazi lenza kumthambo onzulu, ngokuqhelekileyo emilenzeni. Ihlwili linokugqabhuka lihambe liye emiphungeni, nto leyo ebangela i-pulmonary embolism (PE). Uvavanyo lwe-D-dimer lunceda oogqirha ukuba bahlole ukuba kukho ihlwili kwaye bavavanye ukuba ngaba uvavanyo olongezelelweyo, olufana ne-ultrasound, luyimfuneko.
• Ukuxilongwa kwe-Pulmonary Embolism (PE): I-PE yimeko enokuthi ibe yingozi ebomini apho ihlwili livala ukuhamba kwegazi emiphungeni. Uvavanyo lwe-D-dimer luhlala lusetyenziselwa ukukhupha i-PE kwizigulana ezineempawu ezinjengeentlungu zesifuba, ukuphefumula okufutshane, kunye nokukhohlela. Ukuba amanqanaba e-D-dimer aphakanyisiwe, umboneleli wezempilo unokuncoma iimvavanyo ze-imaging njenge-CT pulmonary angiography ukuqinisekisa okanye ukukhupha i-PE.
• Uvavanyo lwe-Disseminated Intravascular Coagulation (DIC): I-DIC yimeko emandundu apho ukujika okungaqhelekanga kwenzeka kuwo wonke umzimba, kulandelwa kukopha kakhulu. Isenokubangelwa lusulelo, ukwenzakala, okanye iingxaki zokukhulelwa. Uvavanyo lwe-D-dimer luluncedo ekuxilongeni kwe-DIC, njengoko amanqanaba e-D-dimer ephakama xa kukho ukujiyisa okubanzi kwigazi.
• Ukubeka iliso kwiZiphazamiso zokujiya kwegazi: Uvavanyo lwe-D-dimer lusenokusetyenziswa ukubeka esweni izigulana ezaziwayo ngokuphazamiseka kwe-clotting okanye eziphantsi konyango lweemeko ezifana ne-DVT okanye i-PE. Ngokulinganisa amanqanaba e-D-dimer, oogqirha banokugqiba ukuba ngaba unyango lusebenza okanye ukuba kukho imfuneko yokungenelela okuqhubekayo.
• Uvavanyo loMngcipheko weSifo sentliziyo: Nangona kungabikho ukusetyenziswa okusemgangathweni, ezinye izifundo zibonisa ukuba amanqanaba aphezulu e-D-dimer anganxulunyaniswa nomngcipheko okhulayo wesifo senhliziyo, kuquka ukuhlaselwa yintliziyo kunye nokubetha. Uphando olongezelelweyo luyafuneka kule ndawo ukuqonda ngcono ubudlelwane phakathi kwamanqanaba e-D-dimer kunye nesifo senhliziyo.

Ululungiselela njani uvavanyo lwe-D-Dimer

Uvavanyo lwe-D-dimer luvavanyo lwegazi olulula olufuna ngokubanzi ukulungiswa okuncinci. Nangona kunjalo, kukho izinto ezibalulekileyo ekufuneka ziqwalaselwe:

• Akukho Lungiselelo lulodwa olufunekayo: Kwiimeko ezininzi, akukho kuzila ukutya okanye amanye amalungiselelo akhethekileyo afunekayo phambi kovavanyo. Ungadla kwaye usele ngokuqhelekileyo ngaphandle kokuba ugqirha wakho ucebisa ngenye indlela.
• Yazisa umboneleli wakho wezempilo malunga namayeza: Amanye amayeza, ngakumbi i-blood thinners (i-anticoagulants) njenge-heparin, i-warfarin, okanye i-aspirin, inokuchaphazela amanqanaba e-D-dimer. Qinisekisa ukuba uxelele ugqirha wakho malunga nawaphi na amayeza owathathayo, njengoko anokuchaphazela iziphumo zovavanyo.
• Yazisa ugqirha wakho malunga noTyando lwakutsha nje okanye ukwenzakala: Ukuba usandul 'ukwenziwa utyando okanye ufumana ukulimala okukhulu, unokuba uphakamise amanqanaba e-D-dimer ngenxa yenkqubo yokuphilisa. Umboneleli wakho wezempilo uya kukuqwalasela oku xa etolika iziphumo zovavanyo lwakho.
• Iingqwalasela zokukhulelwa: Amanqanaba e-D-dimer anokunyuswa kwabasetyhini abakhulelweyo, ngakumbi kwi-trimester yesithathu. Ukuba ukhulelwe, qiniseka ukuba wazisa ugqirha wakho, njengoko uvavanyo lwe-D-dimer lusenokungabi luncedo ekuxilongeni ukuphazamiseka kwe-clotting kulo luntu.

Yintoni omele uyilindele ngexesha lovavanyo lwe-D-Dimer

Uvavanyo lwe-D-dimer yinkqubo elula nebandakanya ukutsalwa kwegazi emithanjeni. Nantsi into onokuyilindela:

• Ukuqokelelwa kwegazi: Umboneleli wezempilo uya kucoca indawo ejikeleze umthambo engalweni yakho, ngokuqhelekileyo ekugobeni kwengqiniba yakho, kwaye afake inaliti ukuqokelela isampuli yegazi. Ukufakwa inaliti kukhawuleza, kwaye inkqubo idla ngokuthatha imizuzu embalwa nje.
• Ukhathalelo lwasemva kovavanyo: Emva kokuba isampuli yegazi ithathiwe, inaliti iyasuswa, kwaye uxinzelelo lufakwe kwindawo yokuyeka ukopha. Unokucelwa ukuba ufake ibhandeji, kodwa ngokuqhelekileyo akukho xesha lokuphumla emva kovavanyo. Unokuphinda uqalise imisebenzi eqhelekileyo ngoko nangoko.
• Ukwenziwa kweLab: Emva kokuba isampuli yegazi iqokelelwe, iya kuthunyelwa kwibhubhoratri ukuze ihlolwe. Iziphumo zovavanyo lwe-D-dimer zidla ngokufumaneka kwisithuba seeyure ezimbalwa ukuya ngosuku, ngokuxhomekeke kwixesha lokwenziwa kwelabhoratri.

Utoliko lweziphumo zovavanyo

Amanqanaba e-D-dimer alinganiswa ngeenanograms ngemilitha (ng/mL) okanye iimicrograms ilitha (µg/L). Nantsi indlela yokutolika iziphumo:

• Amanqanaba eD-Dimer aqhelekileyo:
  • Uluhlu oluqhelekileyo: Uluhlu oluqhelekileyo lwamanqanaba e-D-dimer lunokwahluka kancinci ngokuxhomekeke kwibhubhoratri kunye nendlela esetyenziswayo. Ngokuqhelekileyo, amanqanaba aqhelekileyo angaphantsi kwe-500 ng / mL. Nangona kunjalo, iilebhu ezahlukeneyo zinokuba nemigangatho eyahlukeneyo, ngoko ke kubalulekile ukulandela nogqirha wakho ukuze atolike.
  • Ingcaciso: Inqanaba eliqhelekileyo okanye eliphantsi le-D-dimer libonisa ukuba ukuphazamiseka kwe-clotting akunakwenzeka. Nangona kunjalo, ayikukhuseli ubukho behlwili ngokupheleleyo. Ezinye iimvavanyo zokuxilonga zingafuneka.
• Amanqanaba eD-Dimer anyusiweyo:
  • I-D-Dimer ephakamileyo: Amanqanaba aphakamileyo e-D-dimer angacebisa ubukho behlwili, njengakwimeko ze-DVT, PE, okanye i-DIC. Okukhona liphezulu inqanaba le-D-dimer, kokukhona amathuba okuba enze ihlwili, nangona amanqanaba aphezulu anokubonakala kwezinye iimeko, kubandakanywa ukudumba, usulelo, kunye notyando lwakutsha nje.
  • Ukutolikwa: Ukuba amanqanaba e-D-dimer aphakanyisiwe, iimvavanyo ezongezelelweyo zokuxilonga, ezifana nezifundo ze-imaging (i-ultrasound okanye i-CT scan), zingafuneka ukuba ziqinisekise ubukho begazi.
