How much urine do doctors need to test for toxemia and how many times do they repeat the 24hour test?

24 hour urine test: 24-hr urine looks at the total amount of protein excreted in the urine throughout a 24-hr period. Amount is not important, 24-hr collection is. The test is often repeated weekly or sometimes even more often until delivery. The purpose of repeat testing is to balance timing of delivery - not too early for premature baby, not too late for serious risks to mother.

Depends.: 24-hour urine collection remains the gold standard in determining proteinuria for the purposes of preeclampsia diagnosis and monitoring. However recent studies suggest that spot urinalysis with protein/creatinine ratio is equally accurate and much more convenient.
Your maternal-fetal medicine doctor may repeat your proteinuria determination 1-2 more times during the course of your pregnancy.
