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].
Vacuolization may be present in a cell that has recently phagocytized foreign matter. A monocyte count is part of a complete blood count and is expressed either as a ratio of monocytes to the total number of white blood cells counted, or by absolute numbers. Both may be useful in determining or refuting a possible diagnosis. Monocytosis is the state of excess monocytes in the peripheral blood.
