Definition of White blood cell count. White blood cell count (leukocyte count): The number of white blood cells (WBCs) in the blood. The WBC is usually measured as part of the CBC (complete blood count). White blood cells are the infection-fighting cells in the blood and are distinct from the red (oxygen-carrying) blood cells known as erythrocytes.
The disease is named for the presence of sweet-smelling urine, with an odor similar to that of maple syrup, when the person goes into metabolic crisis. The smell is also present and sometimes stronger in the ear wax of an affected individual at these times.
1 Intermittent maple syrup urine disease is a milder form of the disease. 2  Individuals with this type have a greater level of enzyme activity (approximately 8 to 15% of normal) and often do not have symptoms until 12 to 24 months of age, usually as a result of an illness or surge in protein intake. Classic maple syrup urine disease is the most common type. 2  Individuals with classic maple syrup urine disease have little or no enzyme activity (usually less than 2 % of normal). 3  Infants with this type of maple syrup urine disease will show symptoms within the first several days of life.
