Recumbent renin and aldosterone - Patient information sheet

Recumbent renin and aldosterone

Your doctor has asked us to coordinate a blood test to measure some very specialised hormones, which are produced in the adrenal gland. Unfortunately the samples must be taken when you have been lying down for 30 minutes, and into specially prepared bottles and then handled in a specific way after they are taken. This means that you cannot have them done at your GP surgery.

You can eat and drink and take your medication as normal before this test, although your doctor may have already altered your medication specially in advance of this. Please bring in all your medication with you so these can be documented on the day of this test.

You should expect your stay at the hospital to be about 45 minutes. You may bring someone to stay with you during the test but there is not enough space for more than one person. Children are discouraged, as this can be disruptive to other patients. However, if this poses a particular problem for you please discuss this with the senior nurse in the unit. You should be able to undertake normal activities after the test is finished and it should not interfere with your ability to drive home. 

If you have any queries about the test, please contact:
