Which investigation is most likely to lead to a diagnosis for a 42-year-old woman presenting with signs and symptoms of renal failure?
Understand the Problem
The question is asking about the most appropriate investigation to diagnose the condition of a 42-year-old woman with a history of severe headache, renal failure, hypertension, and abdominal pain. Each of the answer options pertains to different diagnostic imaging or procedures that could provide insight into her condition.
Answer
Estimating eGFR and quantifying proteinuria.
Estimating glomerular filtration rate (eGFR) and quantifying proteinuria (albuminuria) are key tests.
Answer for screen readers
Estimating glomerular filtration rate (eGFR) and quantifying proteinuria (albuminuria) are key tests.
More Information
These tests help assess the kidney function by showing how well kidneys are filtering blood and by detecting any presence of protein in the urine, respectively.
Tips
A common mistake is focusing only on imaging tests; eGFR and proteinuria tests are more practical for initial diagnosis.
