Diğer Adları: Cu; 24-saatlik idrarda bakır; Total bakır; Seruloplazmine bağlı olmayan bakır; Serbest bakır; Hepatik bakır
Resmi adı: Bakır (24 saatlik idrarda, kanda total ve serbest bakır, karaciğerde bakır)
İlişkili testler: Seruloplazmin; Ağır Metaller

Bir Bakışta

Niçin Testi Yaptıracaksınız?

Kan, idrar veya karaciğerdeki bakır miktarını ölçmek, Wilson hastalığının tanısı ve takibine yardımcı olmak ve bazen bakır eksiklikleri veya aşırılıklarını saptamak için bu test yapılır.

Ne Zaman Testi Yaptıracaksınız?

Sarılık, yorgunluk, karın ağrısı, davranış değişiklikleri, titremeler veya doktorunuzun Wilson hastalığı veya nadiren bakır elementi eksikliğine bağlı olabildiğini düşündüğü başka belirtilerin varlığında ve bakırla ilgili bir rahatsızlık için tedavi ediliyorsanız  belli aralıklarla bu test yapılır.

Gerekli Numune Nedir?

Bir kol damarınızdan alınan kan numunesi ve/veya 24 saatlik idrar numunesi, bazen karaciğer biyopsi numunesi kullanılır.

Test için Hazırlık Gerekir mi?

Test için önceden hazırlık yapmak gerekmemektedir.

Test Numunesi

Ne test edilmektedir?

Bu test kan, idrar veya karaciğer (hepatik) içindeki bakır miktarını ölçmektedir. Bakır, vücudun enzimlerin bileşimine kattığı gerekli bir mineraldir. Bu enzimler demir metabolizmasında, bağ dokusu oluşumunda, hücresel düzeyde enerji üretiminde, melanin oluşumunda, sinir sistemi ve beyin fonksiyonlarında rol oynamaktadır.

Bakır elementi kabuklu yemişler, çikolata, mantarlar, kabuklu deniz ürünleri, tam tahıllar, kurutulmuş meyveler ve karaciğer gibi çeşitli besinlerde bulunmaktadır. İçme suyuna su boruların içinden geçerken bakır karışabilir, insanlar yiyecekleri bakır kaplarda pişirip servis yaparken besinlerin içine bakır geçebilir. Normalde bakır vücuda bağırsaklar yoluyla emilir, bir proteine bağlanıp zararsız hale getirilir ve karaciğere taşınır. Karaciğer bakırın bir bölümünü depolayıp geri kalan kısmının çoğunu aposeruloplazmin  denilen bir proteine bağlamaktadır. Bakır bağlandığında aposeruloplazmin, seruloplazmin enzimine dönüşür. Kandaki bakırın yaklaşık % 95’i seruloplazmine bağlıdır. Karaciğer fazla bakırı safraya atar ve vücuttan dışkıyla atılır. Bir miktar bakır idrarla da atılır.

Bakır eksikliikleri veya fazlalıkları nadiren görülmektedir. Kalıtsal bir rahatsızlık olan Wilson hastalığı karaciğer, beyin ve başka organlarda aşırı bakır depolanmasına yol açabilir. Bu durum doku hasarına ve aşağıdaki belirti ve bulgulara neden olabilmektedir:

Böbrekler etkilenmişse idrar üretimi azalabilir veya durabilir. Bu hastalık belirtilerinin bir bölümü ortamdaki bakıra akut veya kronik olarak maruz kalmada veya karaciğer hastalığı gibi rahatsızlıklarda veya bakır metabolizması ve atılımını engelleyen safra yolu tıkanıklarında da görülebilmektedir.

Bakır yetersizliği bazen kistik fibroz ve çölyak hastalığı gibi ciddi emilim bozukluklarında ve özellikle inek sütü formülleriyle beslenen çocuklarda oluşabilmektedir. Hastalık belirtileri arasında nötropeni, osteoporoz ve mikrositik anemi sayılabilir. X kromozomuyla ilişkili kalıtsal Menkes sendromu etkilenmiş bebeklerin beyin ve karaciğerlerinde bakır eksikliğine yol açmaktadır. Esas olarak erkekleri etkileyen hastalık nöbetler, gelişme geriliği, beyinde anormal arter gelişimi ve olağandışı gri, kırılgan dolaşık saç yapısıyla ilişkilidir.

Test için numune nasıl toplanır?

Kolunuzdaki bir atardamardan (venden) alınan kan numunesi ve/veya 24-saatlik idrar numunesi alınır. Bazen doktor karaciğer biyopsisi alır.

Numunenin kalitesinden emin olmak için herhangi bir test hazırlığına gerek var mı?

Hayır, hazırlık gerekmez.
