Interarm BP differences >5 mm Hg may reflect random variation without obstructive disease; leaves open whether repeat protocols improve screening utility in hypertension clinics.
Are interarm blood pressure differences reproducible in patients attending a hypertension clinic?
Clinically meaningful interarm blood pressure differences are generally not reproducible in the absence of obstructive arterial disease and are likely attributable to random variation.
A 2007 study studied this question.
