NOTES:

1. QC materials are supplied with 3 months dating, so each lot should last for 3 months.
2. When a new lot of QC material arrives, select another Control File in the analyzer and enter the data as outlined above.
3. Before the old lot number is depleted or expiresrun both the old lot number and the new lot number concurrently for at least one day. This is to ensure the reliability of the data for the new lot number before putting it into use. If the expected values are not obtained with the new lot number, contact the manufacturer to obtain new control materials.
