Aldosterone/renin ratio

Blood collection after at least 30 minutes rest while lying down. | The following drugs influence the level of aldosterone-renin-ratio. They should be stopped 1 week prior to blood sampling (drugs in bold, 4 weeks) or replaced with the calcium channel blockers (Verapamil type) and alpha-blockers (e.g. Prazosin, Doxazosin or Terazosin), as a lower influence is expected on the aldosterone-renin-ratio.
elevated measurement values due to: beta-blockers, non-steroidal anti-inflammatory drugs (NSAID), central alpha2 agonists (Clonidine, alpha-Methyldopa)
lower measurement values due to: Aldosterone antagonists (<b>Spironolactone, Drospirenone</b>), ACE inhibitors, angiotensin 2 receptor blockers, potassium-saving diuretics (<b>Amiloride, Eplerenone, Triamterene</b>), calcium channel inhibitors (Dihydropyridine), renin inhibitors, loop diuretics | Please follow the cryo instructions. | No post prescription possible.
