| What does an "L" given on a parameter mean? | Lower than reference range |
| What does it mean when an instrument gives "+++" as a result? | The value received is outside of the instrument's linearity. |
| How can one find a result of a parameter that an instrument has previously said id outside of linearity (+++)? | Repeating the test with a dilution of the sample |
| What does it mean when an instrument votes out (gives "...") a result? | The instrument cannot perform the test for some reason. |
| What does it mean when an instrument backlights a result? | The value of the result is potentially inaccurate and should be reviewed |
