home monitoring of blood pressure can be used to monitor and track prehypertensive patients. this can help to raise the awareness of the patient and their doctor if their blood pressure levels rise to hypertensive levels. home monitoring can help to avoid white coat hypertension which results in blood pressure levels being elevated due to the presence of a doctor or physician in a ‘white coat’. monitoring at home or work at regular times each day helps diagnose a patient with prehypertension or hypertension.
