Order of draw trainer
Draws a random set of tubes and asks you to sequence them, using the order CLSI publishes from GP41. Separate variants for venipuncture, blood cultures and capillary collection, because the NHA test plan lists them as three separate requirements.
Tube and additive lookup
Every tube in the CLSI order with its additive, how that additive works, and the tests it serves. A data table rather than prose, drawn from CLSI for the sequence and the WHO phlebotomy guidelines for the additive detail.
