Laboratory testing of digoxin levels Laboratories in the National Health Service (NHS) acute trusts will have arrangements in place for routine therapeutic drug level monitoring of digoxin. Routine assays may not be available on a daily basis. However, local arrangements should exist to ensure the availability of urgent testing in cases of suspected digoxin toxicity 24 hours a day.
