Kidney Function Profile via Transjugular Biopsy (Guided)

Why This Test Is Done

Your doctor may recommend this test if you have symptoms like persistent swelling, unexplained blood in urine, or signs of kidney disease (e.g., high blood pressure, protein in urine). It’s also used to evaluate kidney function when standard blood tests (like creatinine or blood urea nitrogen) don’t provide enough information.

What to Expect Before the Test

You’ll likely need to fast for a few hours before the procedure. Avoid eating or drinking anything except water. Your doctor may also ask you to stop certain medications (like blood thinners) temporarily. Bring your medical records and a list of medications.

The Procedure

A doctor will insert a needle through your blood vessels (usually in your arm or groin) and guide it toward your kidney using imaging (like X-ray or ultrasound). A small tissue sample is taken for microscopic examination. You may feel pressure but won’t feel pain due to local anesthesia.

What Happens After the Test

You’ll rest for a short time afterward, usually in a recovery area. You may experience bruising, soreness, or mild bleeding at the insertion site. Avoid heavy lifting or strenuous activity for a few days. Check with your doctor if you have signs of infection (e.g., fever, increased pain).
