| Introduction |
| A "split urine test" is a method to determine whether the protein discovered in your urine is due to a condition called orthostatic proteinuria. This is a harmless condition that is not uncommon in young people. For reasons that are not well understood, some people leak protein into the urine when they are standing or sitting but not while they are lying down. The split urine test is a simple way to determine if this condition is present. |
| Equipment |
| The test requires that you collect all of your urine for 24 hours. Pick a day when this would be convenient for you. Males might want to buy an inexpensive urinal for easy collection; females should buy an inexpensive basin urinal. |
| You also need two jugs and a funnel. One-half gallon plastic jugs, thoroughly rinsed, are adequate if jugs are not provided. Label the two jugs: (1) Daytime urine and (2) Nighttime urine, respectively. |
| Procedure |
| Perform the following steps on the day that you are going to make the split urine collections. |
| When you first get up, discard the first morning urine. |
| For the rest of the day, collect all of the urine each time you void. Put this urine into the Daytime urine jug. You should be as active as you normally are during the day. |
| In the evening, lie down for two hours before you go to sleep. Just before sleeping, void for the last time during the day and add this urine to the Daytime jug. Lying down for two hours before the nighttime collection avoids contamination of the nighttime collection with urine formed during the day when you were upright. |
| The following morning (approximately eight hours after you went to sleep), collect the first-morning urine and put in the Nighttime urine jug. |
| Take the two jugs to the laboratory. |
| We will notify you when we get the results. |
