24 hours Central Lab Microbiology Diagnostic Services
The Department of Microbiology at Rajarajeswari Medical College and Hospital, Bengaluru functions as 24×7 diagnostic laboratory providing continuous support for emergency, inpatient, outpatient, and critical care services. The laboratory is equipped with advanced automated systems and follows standard protocols to ensure accurate, timely, and reliable results for effective patient management.
1. BD BACTEC FX40 -Automated Blood Culture System
It is used for rapid detection of pathogens in blood. It is especially useful in sepsis cases in NICU and MICU patients.
Turnaround time (TAT): positive blood culture alert within 12-48 hours based on organism growth.
2. VITEK 2 Compact System for Automated Identification and Antimicrobial Susceptibility testing
The VITEK 2 Compact is an automated system used for rapid identification of bacteria and yeast with a short TAT (turnaround time).
3. Fluorescence Immunoassay (FIA) by Finecare FIA Analyzer
The Fluorescence Immunoassay Analyzer is a rapid, quantitative system used in emergency and critical care settings.
Tests performed include:
- Procalcitonin (PCT): Marker for bacterial infection and sepsis
- Troponin I (cTnI): Early marker of myocardial infarction
- D-Dimer: Marker for thromboembolic disorders
- NT-proBNP: Indicator of heart failure
- Turnaround time (TAT): 15-30 minutes
4. Culture and Sensitivity Testing
Routine culture and sensitivity testing is performed on sputum, urine, pus, stool, blood, and other body fluids for identification of pathogens. Antibiotic susceptibility testing is carried out to guide appropriate antimicrobial therapy.
Turnaround time (TAT):
Preliminary report:
24 hours
Final culture & sensitivity report:
48-72 hours
5. Serological Testing – ELISA
ELISA Analyzer
Enzyme-Linked Immunosorbent Assay (ELISA) is performed for detection of infectious disease markers such as HIV, Hepatitis B (HBsAg), Hepatitis C, and Dengue with high sensitivity and specificity.
Turnaround time (TAT):
4-6 hours
6. Rapid Diagnostic Tests
Rapid immunochromatographic tests are performed for quick screening and diagnosis of various infectious diseases and conditions. These include:
HIV, Malaria, Dengue, Hepatitis B (HBsAg), Hepatitis C, C-Reactive Protein (CRP), Antistreptolysin O (ASO), Rapid Plasma Reagin (RPR), Rheumatoid Factor (RA), Urine Pregnancy Test (UPT): A rapid immunochromatographic assay for detection of human chorionic gonadotropin (hCG) in urine, used for early diagnosis of pregnancy.
Turnaround time (TAT):
10-30 minutes
7. Biosafety and Quality Assurance
All microbiological procedures are carried out in a Class II biosafety cabinet, ensuring protection of laboratory personnel, samples, and the environment. The laboratory follows strict infection control measures and quality assurance protocols to maintain high standards of diagnostic accuracy and reliability.
