Types of and time loss through control errors with LIAISON analyzer

Type of control error	Absolute number of control errors	Percentage of control errors (%)	Total time loss during the testing period to reporting (min)	Average daily time loss during the testing period (min)
Light check	18	56	360	8
Positive control GDH	7	22	315	7
Negative control GDH	1	3	45	1
Positive control toxins A&B	5	16	225	5
Negative control toxins A&B	1	3	45	1
Total	32	100	990	22

The average time loss through control errors of the LIAISON analyzer was calculated based on the time loss through a single error type, the absolute number of errors, and the number of days with analytical runs
