This is a critical diagnostic test to pinpoint the source of a serious bloodstream infection (sepsis) in hospitalized patients. A central line is a vital medical tool, but it can sometimes be the entry point for bacteria. When an infection is suspected, your medical team will remove the line and send the tip to our lab. We culture this tip to see if the same bacteria are on the line and in your blood. This is not just a test; it's a high-precision investigation. It provides the definitive answer your doctor needs to confirm the source of the infection and ensure your treatment plan is 100% effective.
