Vitamin B12 vücutta bütün hücreler için gereklidir. Vitamin B12 düzeyinin düşüklüğü kadar yüksekliği de anlamlıdır. Özellikle hematolojik hastalıklarda, solid tümörlerde, otoimmün hastalıklarda, renal hastalıklarda ve enfeksiyon hastalıklarında yüksek serum kobalamin düzeyleri saptanmıştır ve bu yükseklik bazı hastalıklarda prognozla ilişkili bulunmuştur. Serum vitamin B12 yüksekliği dikkate alınmalı ve bu konuda daha fazla çalışma yapılmalıdır

Elevated Vitamin B12 Levels

Vitamin B12 is essential to all cells in the body. Both high levels and low levels of vitamin B12 are significant. High serum cobalamin vitamin B12 levels are found particularly in hematological disorders, solid tumors, autoimmune diseases, renal diseases and infectious diseases; and this elevation is associated with prognosis in some of these diseases. High levels of serum vitamin B12 should be taken into consideration and more studies should be performed on this issue
