FAQ
Frequently asked questions
What is aldosteronism?
Aldosteronism is a condition where the adrenal glands produce too much aldosterone, a hormone that regulates salt and water balance in the body. This can lead to high blood pressure and low potassium levels.
Can other conditions affect potassium levels?
Yes, various factors can influence urine potassium levels, including certain medications, kidney disease, dehydration, and other hormonal imbalances.
How is a random urine sample collected?
A random urine sample can be collected at any time of day. You will be given a sterile container and instructions on how to collect the sample cleanly.
What does a high or low potassium level in urine mean?
High urine potassium can indicate excessive intake or certain kidney conditions, while low urine potassium might suggest the body is retaining potassium due to dehydration or hormonal issues.
