3.  Is it really necessary to collect urine for 24 hours?

Yes, for accurate test results it is essential that all of the urine be collected. Because catecholamines are released at varying times, the one sample not included might be the one with the most hormones in it.

4.  Can my state of mind really affect my test results?

Yes, because catecholamines are released from the adrenal glands in response to stress. If you are anxious or afraid, your catecholamines concentrations may be increased.
