The Catheter Culture test assesses catheterized patients for bloodstream infection risk, vital in preventing catheter-related bloodstream infections (CRBSI) and sepsis. Common organisms causing these infections include, but not limited to, coagulase-negative staphylococci, Candida sp., enteric Gram-negative bacilli, and Staphylococcus aureus. This test is used to detect microorganisms and helps identify potential infection.
