Methylphenidate (trade names Concerta, Methylin, Medikinet, Ritalin, Equasym XL, Quillivant XR, Metadate) is a central nervous system (CNS) stimulant of the phenethylamine and piperidine classes that is used in the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy.
This test measures the amount of monocytes in blood. Monocytes are a type of white blood cell (WBC). This test is used to evaluate and manage blood disorders, certain problems with the immune system, and cancers, including monocytic leukemia[1].
Some of them may be called up if needed, to form the precursors of two other types of white blood cells: tissue macrophages and dendritic cells. But monocytes also have other roles in infection and disease, some of which have nothing to do with tissue macrophages and dendritic cells. When you have a CBC blood test done, monocytes are counted and the number is reported, as well as what percentage of total white blood cells are monocytes.
