Minimum volume required for microbiological investigation is 1ml, place the fluid into a sterile universal container, and tighten the top securely.

Fluid may be inoculated directly into a blood culture bottle, but if a cell count and / or Gram Stain , or microscopy for crystals is required, fluid in a universal container is required. Please note the examination for crystals is only performed on joint fluids if specifically requested or clinical details say ? gout.

Inform the On-call Microbiology BMS via switchboard if an urgent cell count, gram stain or examination for crystals (Joint fluids only)  is required out of hours.
