Jennifer is 41 years old and has been diagnosed with Autosomal Dominant Polycystic Kidney Disease (ADPKD). Jennifer is considered obese and has uncontrolled high blood pressure. She suffers from repeated bouts of lower back pain and had one episode of blood in her urine. She has a family history of ADPKD and her father reached kidney failure and needed to begin dialysis at the age of 55.
Let’s take a closer look at some tests Jennifer's kidney doctor has ordered to better understand how quickly Jennifer might progress to kidney failure 1,2,3.
- Weight210 lbs
- Race (AA/O)O
|0.96||0.50 - 1.20|
|Blood in Urine||Yes|
(Father reached kidney failure at 55)
|Other Risk Factors||Obesity|
- ADPKD Imaging Classification
ESTIMATED AGE AT KIDNEY FAILURE65MRI/CT SCANS
Click on the flags below to see the testing used to confirm risk of rapid disease progression as well as Jennifer’s individual risk
ADPKD=autosomal dominant polycystic kidney disease; US-KL=ultrasound kidney length; ESKD=end stage kidney disease; AA=African American; O=other; eGFR=estimated glomerular filtration rate; PKD=polycystic kidney disease; htTKV=height-adjusted total kidney volume; MRI=magnetic resonance imaging; CT=computed tomography; CKD=chronic kidney disease.
