6. Coulometry: An automated method for measuring chloride which generates
silver ions in the reaction
7. Erythroleukemia: Also known as Acute Myelogenous Leukemia type M6. This type is
associated with either the presence of both erythroid and myeloid
precursors OR strictly erythroid precursors.

13. Gaucher's disease The most common lysosomal storage disease caused by in-
suflcient activity of the lysosomal enzyme glucocerebrosidase
that leads to the deposition of glucocerebroside in cells of the
macrophage-monocyte system.

15. Nephrotic Syndrome: Caused by damage to the kidneys, especially the basement mem-
brane of the glomerulus; which causes abnormal excretion of
protein and red blood cells in the urine. Fats are also present in
the urine in most cases. A foamy appearance of the urine is a key
characteristic of this condition.
