Question

Quizplus · Accepted Answer

A first morning specimen is often used to confirm orthostatic proteinuria, which is a condition where protein is present in the urine in a vertical position but disappears when lying down. This can be detected by comparing a first morning urine specimen to a random specimen collected later in the day. A first morning specimen is not as useful for confirming the other conditions listed.
