9. On Sample Tracking, what does this sample status mean?

• The measurement contains one or more data alarms

• Sampling could not be performed due to sample clot, air bubbles or volume of the sample is too low

• A sample whose ID is duplicated in the Sample ID mode or barcoded-sample is placed on manually assigned position

On reagent overview, the inner block appears (Red) , what does this mean?

• The reagent pack has been used and is empty. There is still

  reagent available in another reagent pack on the analyzer

• Remaining tests in this reagent pack below yellow alarm level.

• No more reagent available for this assay on the analyzer, or no

  diluent on the rotor, or no pretreatment.
