Pleocytosis is an increased cell count {Gk. pleion more}, particularly an increase in white blood cell (WBC) count, in a bodily fluid, such as cerebrospinal fluid (CSF).[1] It is often defined specifically as an increased WBC count in CSF.[2]

It is indicative of an inflammatory, infectious, or malignant condition. Although a CSF pleocytosis or the presence of polymorphonuclear granulocytes in patients suspected of having Guillain-Barre' Syndrome (acute demyelinating polyradiculoneuropathy) is possible,[3][4] should prompt consideration of other diagnoses, such as HIV, CMV, West nile virus infection, Lyme disease (neuroborreliosis), or other infectious or inflammatory conditions. Other rarer associations with CSF pleocytosis can be searched for. Additional tests include HTLV, HSV, sarcoidosis (ACE levels), RPR, VDRL, AFP, copper, hepatitis panel, very long chain fatty acids

Increased white blood cell count in the blood is called leukocytosis.[5]
