B -Leuk

B-Leuk is part of the Complete blood count and Basic blood count. The number of white blood cells (Leuk) is the actual number of white blood cells in proportion to the blood volume. Either a decrease or an increase may be significant. There are five types of white blood cells, which carry out separate tasks in protecting the body against infection: neutrophils (Neut), lymphocytes (Lymf), monocytes (Mono), eosinophils (Eos), and basophils (Baso).

Normally, the result is:

  • over 16 y: 3,3 - 8,2 xE9/l
