Clinical Information (ข้อมูลทางคลินิก):
Detection of significant intravascular catheter microbial contamination is considered meaningful for at least 2 reasons. One is it can help define a healthcare-associated infection.Additionally, a positive catheter culture can indicate that the focus of infection has been removed once the catheter is withdrawn, which, as first suggested by Iannini and Crossley, permits a shorter length of therapy for the infected patient. Thus, the positive predictive value of this test is critical.
 
Reference Value (ค่าอ้างอิง):
No growth
 
Interpretation (การแปลผล):
Patients with catheter related septicemia will usually have >15 colonies per plate. Patients with inflammation at the catheter site but no related septicemia will usually have <15 colonies per plate.
