La ferritin is a amaprotheni elingaphakathi kwe iseli futhi ibophezela ku iron, ukuze itholakale lapho kudingeka.

Ikhona ku isibindi amazinga, lo imisipha yamathambo umkantsha futhi in the ukujikeleza kwegazi ngamanani amancane. Ngaphezu kwalokho, inani le-ferritin egazini lixhunyaniswa ngokuqondile nenani lensimbi egcinwe emzimbeni.

Ukunqunywa kwe-ferritin kulinganisa ngokungaqondile inani lensimbi egazini.

Ingamiselwa:

• thola imbangela uma kwenzeka une-anemia

• thola ukuba khona kokuvuvukala

• thola i-hemochromatosis (i-iron eyengeziwe emzimbeni)

• hlola ukuthi indlela yokwelapha yokwandisa noma yokwehlisa izinga lensimbi emzimbeni isebenza kahle kangakanani

Ukunqunywa kwe-ferritin kwenziwa ngu-a isampula yegazi i-venous, imvamisa lapho kumenyezwa indololwane.

Izimo ezithile zingathinta umthamo we-ferritin:

• bathole ukumpontshelwa igazi phakathi nezinyanga ezi-4 ezedlule

• babe ne-x-reyi ezinsukwini ezi-3 ezedlule

• imithi ethile, njengamaphilisi okulawula inzalo

• ukudla okucebile ngenyama ebomvu

Udokotela angase acele ukuzila ukudla amahora angu-12 ngaphambi kokuhlolwa kwe-ferritin.

Ukuhlushwa kwe ferritin ngokuvamile iphakathi kuka-18 no-270 ng / ml (ama-nanograms ngemililitha ngayinye) emadodeni, phakathi kuka-18 no-160 ng / ml kwabesifazane, futhi ihlukahluka phakathi kuka-7 no-140 ng / ml ezinganeni.

Qaphela ukuthi lokho okubizwa ngokuthi amanani ajwayelekile angahluka kancane ngokuya ngamalabhorethri enza ukuhlaziya (izinga lingahluka futhi ngokuya ngemithombo: phakathi kuka-30 no-300 ng / ml emadodeni kanye no-15 no-200 ng / ml kwabesifazane) . Izinga le-ferritin nalo liyahlukahluka kuye ngobudala, ubulili, ukuzikhandla ngokomzimba, njll.

Izinga eliphezulu le-ferritin (hyperferritinémie) egazini kungaba uphawu lwezifo eziningi:

• an i-hemochromatosis : izinga eliphezulu kakhulu legazi le-ferritin (ngaphezu kuka-1000 ng / ml) lingabangelwa yilesi sifo sofuzo
• ukuphuza ngokweqile

• izifo eziyingozi ezifana nesifo sikaHodgkin (umdlavuza we-lymphatic system) noma i-leukemia

• isifo sokuvuvukala njenge-arthritis noma i-lupus, isifo sika-Still

• ukulimala kwamanyikwe, isibindi noma inhliziyo

• kodwa nangezinhlobo ezithile ze-anemia, noma ngisho nokumpontshelwa igazi okuphindaphindiwe.

Ngokuphambene nalokho, izinga eliphansi le-ferritin (hypoferritinemia) egazini ngokuvamile liwuphawu lokuntuleka kwensimbi. Umbuzo:

• ukulahlekelwa okukhulu kwegazi, ikakhulukazi ngezikhathi ezinzima

• ukukhulelwa

• ukuntuleka kwensimbi ekudleni

• ukopha emgudwini wamathumbu (izilonda, umdlavuza wekoloni, ama-hemorrhoids)
