The cerebrospinal fluid was xanthochromic
and a normal cytochemical analysis was reported.
The supernatant will be colorless and crystal clear in the case of traumatic tap and xanthochromic
(yellow) to hemolyzed (red) if a pathologic bleed has taken place.
(1), (3), (4) In a study comparing the visual and spectrophotometric methods, 80% of CSF samples containing a significant amount of bilirubin were not reported as xanthochromic
by the visual method but were correctly classified by the spectrophotometric method.
His cerebrospinal fluid (CSF) was xanthochromic
and contained abundant red blood cells.
CSF specimens were excluded in any of the following circumstances: clinical signs of meningitis, cerebral hypoxia, or status epilepticus; positive culture; positive Gram staining; bloody aspect; or xanthochromic
supernatant with an erythrocyte-containing centrifuge pellet.
A second CSF specimen obtained 38 hours after admission was xanthochromic
with 17 mg/dL glucose, 3200 mg/dL protein, 500 RBC per [mm.sup.3], and 2400 WBC per [mm.sup.3].
Hematologic/biochemical findings 1 Marked polycythemia, leukopenia, Xanthochromic
CSF hyperkalemia, and hypochloremia; elevated levels of creatinine, bilirubin, globulins, and creatinine phosphokinase 2 ([dagger]) Elevated bilirubin 3 Elevated levels of globulins, Xanthochromic
CSF creatinine phosphokinase, and fibrinogen; decreased bicarbonate 4 NT NT 5 NT Unremarkable * CSF, cerebrospinal fluid; NT, not tested.
