What condition is indicated by an elevation of protein in the urine at 24 weeks of pregnancy?

The condition indicated by an elevation of protein in the urine at 24 weeks of pregnancy is preeclampsia. Preeclampsia is a pregnancy complication characterized by high blood pressure and signs of damage to other organ systems, often the liver and kidneys. One of the key indicators of preeclampsia is proteinuria, which is the presence of excess protein in the urine. This condition typically develops after the 20th week of pregnancy and is associated with significant health risks for both the mother and the baby if left untreated.

Proteinuria occurs because the kidneys are strained by the elevated blood pressure and may begin to leak proteins that would normally be retained. Therefore, the finding of protein in the urine is a critical diagnostic criterion for preeclampsia. Early identification and management of this condition are crucial to prevent further complications such as eclampsia, which involves seizures, or serious issues for the fetus like growth restriction or premature birth.
