Culture & Sensitivity, Aerobic, Catheter Tip- Conventional Identification & Automated AST on Vitek

Culture & Sensitivity, Aerobic, Catheter Tip

Conventional Identification & Automated AST on Vitek

🧪 Test Overview

This test is performed on a catheter tip to detect and identify aerobic bacteria that may be associated with catheter-related infections. The isolated organism is identified using conventional microbiological methods, followed by automated antimicrobial susceptibility testing (AST) on Vitek.

🔬 What Does the Test Detect?

• Aerobic bacterial growth from catheter tips
• Identification of clinically significant bacterial isolates
• Antibiotic susceptibility/resistance patterns
• Antibiotics likely to be effective against the identified organism

🩺 When Is It Recommended?

The test may be advised when a catheter-related infection is suspected, particularly in patients with:

• Fever or chills without an obvious source
• Local redness, swelling, tenderness, or discharge around the catheter site
• Suspected bloodstream infection associated with an indwelling catheter
• Persistent infection despite antibiotic treatment

🧬 Method

Sample: Catheter Tip
Culture: Aerobic bacterial culture
Identification: Conventional microbiological identification
AST: Automated antimicrobial susceptibility testing using Vitek

📋 Report Interpretation

The report may include:

• Organism identified, if growth is detected
• Antibiotic susceptibility results
• Sensitive (S), Intermediate (I), or Resistant (R) classification, as applicable

⚠️ Important

A positive catheter-tip culture does not by itself establish a bloodstream infection. Results should be interpreted along with the patient's symptoms, blood culture findings, and clinical assessment.
