Culture & Sensitivity, Aerobic, Ear Swab- Conventional Identification & Automated AST on Vitek

Culture & Sensitivity, Aerobic, Ear Swab

Conventional Identification & Automated AST on VITEK

Test Overview

This test is performed on an ear swab specimen to detect and identify aerobic bacteria that may be associated with ear infections. Conventional microbiological methods are used for bacterial identification, followed by automated antimicrobial susceptibility testing (AST) using the VITEK system.

What Does the Test Detect?

• Aerobic bacterial pathogens from the ear specimen
• Identification of the causative microorganism
• Antibiotics to which the isolated bacteria are susceptible or resistant

Why Is This Test Done?

It may be recommended when there is:

• Ear discharge or pus
• Persistent or recurrent ear infection
• Suspected bacterial otitis externa or otitis media
• Poor response to empirical antibiotic treatment
• Need for targeted antibiotic therapy

Methodology

Specimen: Ear Swab
Culture: Aerobic bacterial culture
Identification: Conventional microbiological identification
AST: Automated antimicrobial susceptibility testing on VITEK

Clinical Significance

The test helps healthcare professionals identify the causative bacteria and select an appropriate antibiotic based on the organism's antimicrobial susceptibility profile, supporting more targeted treatment.

Sample Requirements

• Specimen: Ear swab collected from the affected site
• Sample collection should preferably be performed before starting antibiotics, when clinically appropriate.
• Proper collection and transport are important for reliable culture results.

Report May Include

1. Organism identified
2. Growth/no growth status
3. Antimicrobial susceptibility results
4. Sensitive (S), Intermediate (I), or Resistant (R) interpretation, where applicable

Important: Antibiotic selection should be based on the laboratory report along with the patient's clinical findings and treating physician's assessment.
