CSF for Bacterial C/S (Aerobic) with Gram Stain

Specimen Required

CSF

Fasting Required

Purpose of the Test

This test is ordered to diagnose and manage bacterial meningitis, which can be a life-threatening condition if not promptly treated.

When this test is required

This test is ordered when a person has symptoms of bacterial meningitis, such as severe headache, fever, nausea, vomiting, sensitivity to light, confusion, and neck stiffness. It is also ordered when a person has a recent history of head trauma, brain surgery, or a compromised immune system, which can increase the risk of developing meningitis.

What the Test Detects

This test includes a gram stain and bacterial culture. The gram stain is a quick test that allows the laboratory technician to see the bacteria under a microscope and determine their shape and staining characteristics. The bacterial culture is a more sensitive test that identifies the specific bacteria present in the sample and determines their antibiotic susceptibility.

Preparation for the Test

No specific preparation is required for this test. However, the healthcare provider may recommend stopping certain medications before the test, such as blood-thinning medications or antibiotics.

Sample Requirements

This test requires a sample of cerebrospinal fluid, which is obtained through a lumbar puncture or spinal tap.

Additional Notes

Bacterial meningitis is a serious condition that requires prompt diagnosis and treatment. Delayed treatment can lead to severe complications, such as brain damage, hearing loss, and death. If you have symptoms of meningitis, seek medical attention immediately.
