TY - JOUR T1 - Effect on the white cell count of contaminating cerebrospinal fluid with blood. JF - Archives of Disease in Childhood JO - Arch Dis Child SP - 400 LP - 401 DO - 10.1136/adc.56.5.400 VL - 56 IS - 5 AU - J P Osborne AU - B Pizer Y1 - 1981/05/01 UR - http://adc.bmj.com/content/56/5/400.abstract N2 - Retrospective analysis of heavily blood-stained cerebrospinal fluid shows that there are fewer white cells found in this fluid than would be expected by calculations using the peripheral blood red to white cell ratio. This phenomenon may disguise a true leucocytosis. ER -
