Inkqubo yovavanyo
| 1 | Vula iphakheji ye-reagent yebhegi yefoyile ye-aluminiyam uze ukhuphe isixhobo sovavanyo. Faka isixhobo sovavanyo ngokuthe tye kwindawo yokuhlaziya umzimba. |
| 2 | Kwiphepha lasekhaya le-interface yokusebenza ye-immune analyzer, cofa u-“Standard” ukuze ufake i-interface yovavanyo. |
| 3 | Cofa u-“QC Scan” ukuze uskene ikhowudi ye-QR ngaphakathi kwekhithi; faka iiparameter ezinxulumene nekhithi kwisixhobo kwaye ukhethe uhlobo lwesampulu. |
| 4 | Jonga ukuhambelana kwe "Igama leMveliso", "Inombolo yeBatch" njl. njl. kwi-interface yovavanyo ngolwazi olukwi-kit marker |
| 5 | Emva kokuba ulwazi luqinisekisiwe, khupha iisampulu zokuxuba, yongeza i-20µL yesampulu yeserum, uze udibanise kakuhle. |
| 6 | Yongeza i-80µL yesisombululo esixutyiweyo esingentla kumngxuma wesampulu yesixhobo sovavanyo. |
| 7 | Emva kokongeza isampuli epheleleyo, cofa u-“Timing” kwaye ixesha eliseleyo lovavanyo liza kuboniswa ngokuzenzekelayo kwi-interface. |
Injongo Yokusebenzisa
Le khithi iyasebenza ekufumaneni ubungakanani be-in vitro yasimahlai-β-subunit ye-gonadotropin ye-chorionic yomntu (i-F-βHCG)kwisampulu yeserum yomntu, efanelekileyo kuvavanyo oluncedisayo lomngcipheko kubasetyhini wokuthwala umntwana one-trisomy 21 (Down syndrome) kwiinyanga ezi-3 zokuqala zokukhulelwa. Le khithi inika kuphela i-β-subunit yasimahla yeziphumo zovavanyo lwe-human chorionic gonadotropin, kwaye iziphumo ezifunyenweyo mazisetyenziswe kunye nolunye ulwazi lweklinikhi ukuze kuhlalutywe. Kufuneka isetyenziswe kuphela ziingcali zempilo.
Isishwankathelo
I-F-βHCGyi-glycoprotein equlathe ii-α kunye nee-β subunits, ezimalunga ne-1%-8% yenani lilonke le-HCG egazini likamama. Le protein ikhutshwa yi-trophoblast kwi-placenta, kwaye ichaphazela kakhulu ukungaqheleki kwe-chromosome. I-F-βHCG yeyona nto isetyenziswa kakhulu kwi-serological xa kuchongwa isifo se-Down syndrome. Kwiinyanga ezi-3 zokuqala zokukhulelwa (iiveki ezi-8 ukuya kwezi-14), abafazi abanomngcipheko omkhulu wokuzala umntwana one-Down syndrome banokuchongwa ngokusebenzisa i-F-βHCG, i-plasma protein-A (PAPP-A) enxulumene nokukhulelwa kunye ne-nuchal translucency (NT) ultrasound.
