[Why are blood pressure values higher in the doctor's office than at home?].

Blood pressure values measured by the patients at home are lower than those measured during medical consultation. To test whether the person measuring the blood pressure is responsible for this difference, the blood pressure of 127 patients was measured first by the doctor and then by the patients themselves during the consultation. There was a good agreement and no significant difference between the two measurements. Values taken at home were however significantly lower. Our results indicate, that difference between clinic and home blood pressure values does not depend on the person performing the measurement.
