The assessment of digoxin concentration should be performed 10 days after treatment has started, in order to achieve a relatively constant plasma concentration. However if toxic effects are suspected it is also advisable to perform the assessment after just 3-5 days. The blood peak occurs 2 to 5 hours after administration. Levels should be determined 8 hours after administration of the drug, to assess the presence of adequate concentrations for therapeutic purposes, or after 2-5 hours to detect possible toxicity.

Storage/shipping methods: serum must be stored and shipped at refrigeration temperature;

Reception days: every day from Monday to Saturday;
