Aldosterone and Renin

Related tests: Cortisol; Electrolytes; Potassium; Sodium

Common Questions

1.  Are there any other precautions I should take before the test?

Liquorice can mimic aldosterone properties and should be avoided for at least two weeks before the test. This refers only to the actual products of the liquorice plant (hard liquorice); most soft liquorice and other forms of liquorice confectionary sold in the UK do not actually contain the plant extract. Check the packages label if you are not certain, or bring a package with you to ask your doctor. Stress and strenuous exercise may also alter the results.
