The fees for the three hypertension tests range from 150-300 yuan, depending on the level of the hospital, regional differences, different health insurance policies, etc. For details, you can consult your local hospital. Hypertension mainly includes renin, angiotensin and aldosterone, which are mainly used to determine whether the patient’s hypertension is primary or secondary, and these three tests require precautions, such as: First, blood should be sent to the laboratory immediately after extraction, because with the extension of time, the activity of hormones may decline, affecting the test results. Second, the results of these three tests have not been standardized yet, so the same specimen may have different reference values in different hospitals and laboratories. Third, because the secretion of hormones is affected, such as posture, body position, exercise, emotions, etc. can affect, so the general need to measure the blood specimen 3-4 times to comprehensive assessment.
