Differential diagnosis of headache includes: Migraine, tension-type headache, cluster headache, seizure, meningitis, encephalitis, neurosyphilis, SAH, subdural hematoma, brain tumor, hypertensive encephalopathy, brain abscess, multiple sclerosis, hemorrhagic stroke, Wernickes encephalopathy, and drug toxicity etc.^[1]^[2]^[3]^[4]^[5]^[6]^[7]^[8]^[9]^[10]^[11]^[12]^[13]^[14]^[15]^[16]^[17]^[18]^[19]

Diagnsotic Labs For Meningitis

Diagnosis of meningitis, is based on clinical presentation in combination with CSF analysis. CSF analysis has major role for diagnosis and rule out other possibilities. The following table summarizes the CSF findings in different types of meningitis.^[2]^[3]^[4]^[5]^[6]


Cerebrospinal fluid level	Normal level	Bacterial meningitis^[5]	Viral meningitis^[5]	Fungal meningitis	Tuberculous meningitis^[29]	Neoplastic meningitis^[2]
Cells/ul	< 5	>300	10-1000	10-500	50-500	>4
Cells	Lymphocyte	Leukocyte > Lymphocyte	Lymphocyte > Leukocyte	Lymphocyte > Leukocyte	Lymphocyte > Leukocyte	Lymphocyte > Leukocyte
Total protein (mg/dl)	45-60	Typically 100-500	Normal or slightly high	High	Typically 100-200	>50
Glucose ratio (CSF/plasma)^[3]	> 0.5	< 0.3	> 0.6	<0.3	< 0.5	<0.5
Lactate (mmols/l)^[4]	< 2.1	> 2.1	< 2.1	>3.2	> 2.1	>2.1
Others	Intra-cranial pressure (ICP) = 6-12 (cm H2O)	CSF gram stain, CSF culture, CSF bacterial antigen	PCR of HSV-DNA, VZV	CSF gram stain, CSF india ink	PCR of TB-DNA	CSF tumour markers such as alpha fetoprotein, CEA
