Patient's question:
A newborn with purulent meningitis was on antibiotics for four days and had a follow-up white blood cell count of 2. The cerebrospinal fluid protein level was 0.65, and both protein and sugar tests were positive. During hospitalization, the cerebrospinal fluid white blood cell count was 24. What does a positive protein test in cerebrospinal fluid indicate?Doctor's answer:
Cerebrospinal fluid protein qualitative positivity indicates that the child is sick. Newborn cerebrospinal fluid protein qualitative testing is a method of cerebrospinal fluid testing. It is usually negative. If it is positive, it may be caused by a disease. Cerebrospinal fluid protein is significantly elevated in central nervous system malignancies such as purulent meningitis, tuberculous meningitis, spinal canal and metastatic cancer, cerebral hemorrhage, subarachnoid hemorrhage, and obstruction. In patients with viral meningitis, fungal meningitis, Japanese encephalitis, poliomyelitis, meningovascular syphilis, paralytic dementia, and cerebral thrombosis, mild elevation of cerebrospinal fluid protein is relatively common.
