A high blood pressure of 138mmHg and a low pressure of 97mmHg is high and needs to be retested to determine if it is normal. Generally speaking, the normal reference value of blood pressure is high pressure less than 140mmHg, and low pressure less than 90mmHg. However, human blood pressure is fluctuating, and it may rise transiently under emotional excitement, strenuous activities, or sleep deprivation, so it is necessary to retest to determine whether the blood pressure is normal or not. Currently, the diagnostic criteria for hypertension are high pressure greater than or equal to 140mmHg and low pressure greater than or equal to 90mmHg when measured three times in the resting state within the same day, if the diagnostic criteria are met after retesting, then the blood pressure is likely to be abnormal, and it is recommended to consult a doctor for standardized diagnosis and treatment in a timely manner.
