Qhov sib txawv tseem ceeb ntawm cov ntshav hlau thiab ferritin yog cov hlau hauv cov ntshav yog cov hlau ncig ntawm cov hlau txuas mus rau transferrin thiab serum ferritin, thaum ferritin yog cov protein ntau hauv cov cell uas khaws cov hlau hauv lub xov tooj thiab tso tawm hauv kev tswj hwm.
Iron yog ib qho khoom noj tseem ceeb. Nws muaj ntau yam haujlwm, xws li kev tsim cov qe ntshav liab noj qab haus huv. Nws yog ib qho tseem ceeb heev ntawm hemoglobin. Lub cev tsis tuaj yeem tsim cov hlau ntawm nws tus kheej, yog li nws yuav tsum nqus hlau los ntawm cov khoom noj thiab tshuaj ntxiv. Feem ntau, hlau yog thauj hauv lub cev los ntawm cov protein hu ua transferrin. Hauv cov neeg noj qab haus huv, feem ntau ntawm cov hlau hauv lub cev tau muab tso rau hauv hemoglobin hauv cov qe ntshav liab. Cov hlau seem yog khaws cia hauv ferritin. Yog li ntawd, cov ntshav liab thiab ferritin pab ntsuas cov hlau hauv lub cev.
Serum Iron yog dab tsi?
Serum hlau yog tus nqi ntawm cov hlau ncig ua ke rau cov tshuaj hloov pauv thiab cov ntshav ferritin. Kev ntsuam xyuas cov hlau nplaum ntsuas qhov nyiaj ntawm cov hlau ncig. Nquag, 90% ntawm cov ntshav hlau yog khi rau kev thauj cov protein. Cov seem ntawm 10% ntawm cov ntshav hlau yog khaws cia hauv ferritin. Cov kws kho mob xaj qhov kev sim no thaum lawv xav tias muaj hlau tsis txaus. Iron deficiency tuaj yeem ua rau mob ntshav qab zib thiab lwm yam teeb meem kev noj qab haus huv. Feem ntau, 65% ntawm cov hlau hauv lub cev yog nyob rau hauv hemoglobin hauv cov qe ntshav liab. Kwv yees li 4% yog nyob rau hauv myoglobin molecules. Nyob ib ncig ntawm 30% ntawm cov hlau yog khaws cia hauv ferritin lossis hemosiderin hauv tus po, pob txha thiab daim siab. Ib qho me me ntawm cov hlau tuaj yeem pom hauv lwm cov molecules hauv cov hlwb. Tsis muaj ib qho ntawm cov hlau no tuaj yeem siv ncaj qha los ntawm kev sim cov ntshav. Txawm li cas los xij, qee cov hlau yog ncig hauv cov ntshav. Transferrin yog ib qho molecule tsim los ntawm lub siab uas khi rau ib lossis ob lub hlau. Circulating hlau feem ntau yog khi rau cov protein hloov pauv. Qhov kev ntsuam xyuas rau cov hlau hauv cov ntshav ntsuas cov hlau ions uas khi rau kev hloov pauv thiab khaws cia hauv cov ntshav ferritin. Tsis tas li ntawd, qhov kev siv cov kua qaub ib txwm siv rau cov txiv neej yog 65 txog 176 μg / dL thiab rau cov poj niam yog 50 txog 170 μg / dL.
Daim duab 01: Iron-deficiency Anemia
Serum iron test yog ib qho tseem ceeb rau cov txheej txheem kuaj mob xws li anemia, iron deficiency anemia, anemia ntawm cov kab mob ntev thiab haemochromatosis.
Ferritin yog dab tsi?
Ferritin yog ib qho protein ntau hauv cov cell uas khaws cov hlau hauv lub xov tooj ntawm tes thiab tso tawm hauv kev tswj hwm. Nws yog ib tug globular protein complex. Kev ntsuam xyuas ferritin ntsuas tus nqi ntawm ferritin hauv cov ntshav. Qhov no yog ib qho kev ntsuas tsis ncaj ntawm cov hlau ncig uas khi rau lossis khaws cia hauv cov ntshav ferritin. Cov protein no yog tsim los ntawm yuav luag txhua yam muaj sia nyob. Nws khaws cov hlau rau hauv daim ntawv soluble thiab tsis muaj tshuaj lom.
Daim duab 02: Ferritin
Ferritin yog tsim nyob rau hauv feem ntau cov ntaub so ntswg raws li cytosolic protein. Ib qho me me secretes rau hauv cov ntshav uas nws ua haujlwm raws li cov khoom siv hlau. Tsis tas li ntawd, serum ferritin yog ib qho kev kuaj mob rau cov hlau deficiency anemia. Qhov kev siv ferritin ib txwm nyob hauv cov ntshav rau cov txiv neej yog 18-270 ng / mL, thiab cov poj niam yog 30-160 ng / mL.
Dab tsi zoo sib xws ntawm Serum Iron thiab Ferritin?
- Ob nqe lus muaj feem cuam tshuam rau hlau.
- Lawv tseem ceeb heev hauv kev ntsuas tag nrho cov hlau ncig.
- Ob leeg tuaj yeem ntsuas tau los ntawm kev siv cov ntshav los ntawm kev kuaj tshwj xeeb.
- Cov no yog cov cim ntsuas rau cov hlau tsis muaj peev xwm anemia.
Qhov txawv ntawm Serum Iron thiab Ferritin yog dab tsi?
Serum hlau yog tus nqi ntawm cov hlau circulating khi rau transferrin thiab serum ferritin, thaum ferritin yog ib qho intracellular protein uas khaws cov hlau hauv lub xov tooj ntawm tes thiab tso tawm hauv kev tswj hwm. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm cov ntshav ntshav thiab ferritin. Tsis tas li ntawd, cov ntshav ntshav yog ntsuas los ntawm kev kuaj ntshav ntshav, thaum ferritin ntsuas los ntawm cov ntshav ferritin lossis ferritin kuaj.
Cov hauv qab no infographic tabulates qhov sib txawv ntawm cov ntshav hlau thiab ferritin rau ib sab ntawm kev sib piv.
Summary – Serum Iron vs Ferritin
Hlau yog ib qho tseem ceeb hauv lub cev siv rau kev loj hlob thiab kev loj hlob. Serum hlau thiab ferritin pab ntsuas hlau hauv lub cev. Serum hlau yog cov nyiaj ntawm cov hlau ncig uas yog khi rau kev hloov pauv hauv cov ntshav thiab cov ntshav ferritin, thaum ferritin yog cov protein ntau hauv cov cell uas khaws cov hlau hauv lub xov tooj ntawm tes thiab tso tawm hauv kev tswj hwm. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm cov kua qaub thiab ferritin.
