\n– Hemoglobin, alyuvarlardaki oksijen ta\u015f\u0131yan proteindir; genellikle hemogram i\u00e7inde \u00f6l\u00e7\u00fcl\u00fcr.
\n– “Hemoglobin” ad\u0131 hemogram, HbA1c, hemoglobin varyant analizi (HPLC) ve idrarda hemoglobin gibi farkl\u0131 testlerde ge\u00e7er; bunlar ayn\u0131 test de\u011fildir.

Hemoglobin Nedir ve Ne \u0130\u015fe Yarar?<\/h2>\n

Alyuvarlar, oksijeni akci\u011ferlerden dokulara ta\u015f\u0131r. Bu ta\u015f\u0131ma i\u015fini alyuvarlar\u0131n i\u00e7indeki demir bak\u0131m\u0131ndan zengin hemoglobin proteini yapar. H\u00fccrelerin b\u00fcy\u00fcmesi, \u00e7o\u011falmas\u0131 ve enerji \u00fcretmesi i\u00e7in oksijene ihtiyac\u0131 vard\u0131r; bu nedenle hemoglobin d\u00fczeyi alyuvarlar\u0131n sa\u011fl\u0131\u011f\u0131 hakk\u0131nda bilgi verir (MedlinePlus, Hemoglobin Test).<\/p>\n

D\u00fc\u015f\u00fckl\u00fck Nedir?<\/h2>\n

MedlinePlus, d\u00fc\u015f\u00fck hemoglobinin farkl\u0131 anemi t\u00fcrlerinin, demir ve vitamin B12 gibi baz\u0131 besin \u00f6\u011felerinin eksikli\u011finin, yaralanma ya da a\u011f\u0131r adet kanamas\u0131 gibi kan kayb\u0131n\u0131n ve baz\u0131 kal\u0131tsal durumlar\u0131n i\u015fareti olabilece\u011fini belirtir.<\/p>\n

Anemi tek bir hastal\u0131k de\u011fil, farkl\u0131 nedenlere ba\u011fl\u0131 bir tablodur. Bu y\u00fczden hekim hemoglobinin yan\u0131nda alyuvar boyutunu, hematokriti<\/a> ve gerekirse demir g\u00f6stergelerini birlikte inceler.

Hemoglobin neden y\u00fckselir sorusunun tek bir yan\u0131t\u0131 yoktur: y\u00fcksek hemoglobin her zaman bir hastal\u0131\u011fa i\u015faret etmez. MedlinePlus, y\u00fcksek rak\u0131mda ya\u015faman\u0131n hemoglobini y\u00fckseltebildi\u011fini; susuzluk, sigara, baz\u0131 ila\u00e7lar, aktivite d\u00fczeyi ve beslenmenin de sonucu etkileyebildi\u011fini belirtir. Bunlar\u0131n yan\u0131nda baz\u0131 akci\u011fer ve kalp ile ilgili durumlar, kemik ili\u011finin fazla alyuvar \u00fcretmesine yol a\u00e7an hastal\u0131klar ve uyku apnesi gibi durumlar da y\u00fcksek hemoglobinle ili\u015fkilendirilebilir (MedlinePlus).<\/p>\n

Bu nedenle y\u00fcksek bir sonu\u00e7 tek ba\u015f\u0131na yorumlanmaz. Hekim ya\u015fanan ortam\u0131, sigara kullan\u0131m\u0131n\u0131, ila\u00e7lar\u0131 ve di\u011fer kan de\u011ferlerini birlikte de\u011ferlendirir; gerekirse testin tekrarlanmas\u0131n\u0131 ister.<\/p>\n
