Which Canary Yellow Tube is used for blood cultures (Bacterial Cultures) and contains SPS?

• A. Canary Yellow Tube — ACD
• B. Gray Tube — Na Fluoride/K Oxalate
• C. Lavender Tube — EDTA
• D. Canary Yellow Tube — SPS

Answer: (D)

The key idea is that a Canary Yellow tube used for blood cultures contains SPS, which is specifically added to support the recovery and growth of bacteria in culture. SPS acts as the additive that makes this tube suitable for collecting blood intended for bacterial culture, helping to preserve the organisms and improve culture yield. The other Canary Yellow tube option uses a different additive (ACD) and is intended for tests like DNA studies or transfusion-related applications, not for blood cultures. The Gray tube with fluoride/oxalate, and the Lavender tube with EDTA, are designed for other routine tests and do not serve the purpose of blood culture collection.
