Reconstitution
Carefully remove the rubber stopper from the vial. Add exactly 3.0 ml of distilled water into the vial. Replace the stopper and allow to sit for 10 to 15 minutes at room temperature. Swirl the vial to dissolve the contents until homogeneity.
Storage conditions
Stored at +2 to +8 °C unopened controls are stable until the expiry date which is stated on the vial labels. The reconstituted controls can be stored up to four weeks tightly capped and light protected at +2 to +8 °C. If the controls cannot be analysed within this period, they should be stored frozen below –18 °C (up to 3 months).
