Angiography > Exams & Procedures > Kidney/Renal-Renal Vein Blood Sampling
Blood samples are taken from the veins around the kidneys to diagnose renal hypertension.
Local anaesthetic is given to numb the area. A small, thin tube called a catheter is inserted into a vein, usually the femoral vein, near the groin. The catheter is placed close to the kidneys and various blood specimens are obtained.
Once the procedure is completed, the radiologist will press at the puncture site for about five minutes.
The procedure takes about one hour. You will be on bed rest for two hours after the procedure.
No special preparation is required.
