Hypertension triple test is plasma renin, angiotensin, aldosterone levels, can take terazosin hydrochloride. Terazosin belongs to the α-blocker, can be antagonized by the α-adrenergic receptor relaxation of peripheral vasculature to achieve antihypertensive effect, and its antihypertensive mechanism of renin – angiotensin – aldosterone system has less impact. Antihypertensive drugs that have an effect on the results of the three tests for hypertension include β-blockers, such as bisoprolol and metoprolol; diuretics, such as furosemide and spironolactone; angiotensinase inhibitors, such as captopril and perindopril; and angiotensin receptor inhibitors, among others, such as valacyclovir and valsartan. The above medications may cause false negative or false positive results. Before taking the hypertension test, you should inform your doctor about the antihypertensive medication you are taking, and ask your doctor to adjust your medication regimen to prevent inaccurate test results.
