  • Antibiotic treatment before sampling can inhibit bacterial growth and skew results
  • Haemorrhagic sample may interfere with biochemistry (protein level not interpretable)

5-10 days (preleminary results in a few hours: Gram staining, cytology, biochemistry)

  • Sample nature: Pleural fluid, ascitic fluid, other effusion fluid
  • Recommended volume: At least 1 mL per container/tube
  • Type of container: Sterile tube/container (for microbiology) + citrate or EDTA tube (for cytology)+ blood culture vial if possible (a pair or at least 1 anaerobic vial)
