High blood pressure five standing for three hours can draw blood

The five items of hypertension

usually refer to renin, angiotensin, aldosterone, adrenocorticotropin and cortisol, which are mainly used to distinguish essential hypertension from secondary hypertension. The test usually requires three blood draws. If the first two blood draws are taken after standing for three hours, it may affect the accuracy of the measurement. Usually, blood draws are taken in a lying position. If it is the third blood draw, it should be carried out after standing for two hours. Standing for three hours will not affect the measurement results, so it is OK.
