One clinic visit cost L26,400 ($17), laboratory tests cost L52,700 ($34) and an ambulatory blood pressure measurement cost L100,000 ($64.50). The cost of therapy was L1,450 ($0.94) per day. The B1 strategy (ABPM for all patients and an ABPM screening every two years for those found to have white-coathypertension and therefore not treated) cost $569,073 (CI: $602,058-$538,634) and led to a saving of $110,819 (CI: $77,834-$141,258). Savings ranged between $93,057 (CI: $62,611-$123,849) and $120,964 (CI: $87,983-$153,946), depending on the cut-off point chosen. For strategy B2 (ABPM for all patients and a further ABPM screening every year for those found to have white-coathypertension and therefore not treated) there was a saving of $100,348 over the 6 year period.
