MSFinals-5290
A 35-year-old male contacts his GP at 2PM to schedule his blood tests following a recent visit to his psychiatrist. The psychiatrist has raised his lithium dosage and requested that the GP arrange for lithium levels to be checked at the appropriate time after taking the medication. The patient took his first increased dose of lithium at 10AM (4 hours ago).
In how many hours should the GP schedule the blood test to be taken?
