Frequently Asked Questions

Will medications affect my testing?

Yes! You must be off of the following medications for at least 6-8 weeks:

  • Spironolactone (Aldactone)
  • Eplerenone (Inspra)
  • Triamterene (Dyrenium, Dyazide, or Maxzide)
  • Amiloride (Midamor, Moduretic)

We ask that you be off of the following medications for at least 4 weeks:

  • Potassium-wasting diuretics (e.g. furosemide or Lasix)
  • Chewing tobacco
  • Licorice-containing products

Lastly, we ask that you stop any biotin or "hair" or "nails" multivitamins for at least two weeks prior to your arrival to the NIH.

Are any medical conditions contraindicated to me coming to the NIH for testing

Yes! If you have severe heart, lung, gut, liver, kidney, blood, or psychiatric disorder, you might not qualify for testing. The study team will let you know after reviewing your outside records if you qualify for testing.

Can my family members get tested as well?

Possibly. Family members may qualify to get genetic testing under this study if Primary Aldosteronism (PA) is confirmed in you. Family members may also qualify for full testing for PA under a similar, but different, protocol run by the same study team.
