Three days before collecting urine,
as well as on the day of collection, exclude from your diet all products that color the urine: beetroot,
tomato,
carrot,
citrus fruits,
strong tea,
coffee.
How to collect 24-hour urine:
On the day of urine collection, discard the first (night) portion into the toilet.
Then,
starting from the second portion,
collect the urine in a 3-liter jar throughout the day.
The next morning, also collect the night portion in the jar.
Mix the urine and use a measuring container to accurately measure the total daily amount of urine.
Deliver 100 ml to the laboratory with an indication of the diagnosis and the total daily volume.
