ALBUMIN FROM OVERNIGHT URINE COLLECTION

The purpose of the examination is to identify incipient kidney damage reliably early enough. The quantity of albumin excreted during a night’s rest is examined. Stress increases the excretion of albumin and induces incorrect results.

Preparation

Do not collect urine during your menstrual period. You can start collecting urine when two days have passed since the end of visible menstrual bleeding. If you have a sudden urinary tract infection, start the collection when a physician has confirmed that you have recovered. Do not consume alcohol during the examination period. Only light exercise is recommended after 6 p.m.
