Le Fer yog ib qho tseem ceeb ntawm cov khoomhemoglobin cov, cov protein muaj nyob hauv Cov qe ntshav liab thiab nws lub luag haujlwm tseem ceeb yog thauj covOxygen nyob rau hauv lublub koom haum.

Nws tseem yog ib qho tseem ceeb rau lwm lub cev ua haujlwm, xws li DNA synthesis lossis qee yam tshuaj tiv thaiv enzymatic.

Kwv yees li 70% ntawm lub cev hlau yog khi rauhemoglobin cov, thaum tus so yog tsau ntawm thauj cov protein (Cov tshuaj ferritine or kev hloov pauv) lossis khaws cia rau hauv qee cov ntaub so ntswg ntawm lub cev. Piv txwv li, hauv cov pob txha pob txha, hlau yog khaws cia thiab siv raws li qhov xav tau los ua cov qe ntshav liab tshiab.

Cov hlau los ntawmkhoom noj khoom haus (lub siab thiab lwm yam nqaij, qe, ntses, los yog zaub ntsuab). Nws yog qhov tsim nyog tshwj xeeb thaum lub sij hawm loj hlob, cev xeeb tub, pub niam mis lossis tom qab los ntshav hnyav.

Qhov kev ntsuam xyuas tso cai rau koj los ntsuas cov qib ntawm cov hlau hauv lub cev thiab seb nws zoo li cas metabolized (xws li assimilated los ntawm lub cev). Qhov no tso cai rau tus kws kho mob kuaj tau piv txwv li kev tsis txaus hlau (hlau deficiency), hlau deficiency anemia (anemia vim tsis muaj hlau), hemochromatosis (ntau cov hlau ntau hauv lub cev), tab sis kuj los xyuas cov khoom noj khoom haus ntawm tus neeg mob.

Ceeb Toom: Kev txiav txim siab ntawm ferritin feem ntau ua tiav ua ntej, qhov ntau npaum ntawm cov hlau ib leeg tsis tshua muaj qhia (nws tuaj yeem ua tiav nrog qhov ntau npaum ntawm kev hloov pauv hauv lub hom phiaj thib ob).

Tus qauv kub rau kwv yees tus nqi ntawm cov hlau hauv lub cev yogkev kuaj mob pob txha, los ntawm cov pob txha pob txha aspiration los yog biopsy. Nws yog ib qho kev kuaj mob thiab raug mob uas yog li ntawd tsis tau ua txhua hnub.

Kev txiav txim siab ntawm cov ntshav hlau (hauv cov ntshav) tuaj yeem ua los ntawm cov ntshav venous, feem ntau yog coj los ntawm lub luj tshib. Nws tsis tshua ua tiav ib leeg vim nws muaj qhov ntsuas me me. Feem ntau, nws tau ua ke nrog lwm cov kev ntsuam xyuas xws li cov ntshav hloov ntshav, thiab qee zaum ntawm cov ntshav ferritin, soluble transferrin receptors lossis intraerythrocytic ferritin.

Raws li cov hlau qib siab dua thaum sawv ntxov, qhov kev ntsuam xyuas yuav tsum zoo dua nyob rau lub sijhawm no ntawm hnub.

Cov qib hlau hauv cov ntshav yog ib txwm nyob nruab nrab ntawm 70 thiab 175 μg / dl (micrograms ib deciliter) hauv cov txiv neej thiab nruab nrab ntawm 50 thiab 150 μg / dl hauv cov poj niam, tab sis nws txawv heev hauv tib neeg thaum nruab hnub (amplitude ntawm 30 txog 40. %). Qhov no yog vim li cas nws yog ib qho tseem ceeb kom koom nrog qhov ntau npaum ntawm cov kev hloov pauv thiab xam cov Transferrin saturation coefficient.

High serum hlau tej zaum yuav yog ib qho cim ntawm, ntawm lwm yam:

• a hemochromatosis  (hlau overload)
• hemolytic anemia (kev puas tsuaj ntxov ntxov ntawm cov qe ntshav liab hauv cov ntshav)
• kab mob siab necrosis
• kab mob siab (mob ntawm daim siab)
• mob ntsws
• mob cawv
• rov muab ntshav rov qab

Ntawm qhov tsis sib xws, qib qis ntawm cov hlau tuaj yeem txuas rau:

• ntshav poob tseem ceeb, tshwj xeeb tshaj yog thaum lub sij hawm hnyav
• cev xeeb tub
• hlau deficiency (hlau deficiency) txuas rau zaub mov
• ib qho kev tsis txaus uas cuam tshuam rau qhov tsis muaj peev xwm nqus tau hlau zoo
• los ntshav hauv plab hnyuv (ulcers, colon cancer, hemorrhoids)

tab sis kuj o, kab mob, tom qab phais, thiab lwm yam.

Ib zaug ntxiv, nws yuav tsum tau muab sau tseg tias qhov koob tshuaj no, nqa tawm hauv kev sib cais, tsis muaj kev txaus siab rau kev kho mob.
