Why This Test Might Be Ordered

Your doctor may recommend this test if you have a family history of kidney problems, birth defects involving the kidneys, or if you’ve been diagnosed with a condition like renal dysplasia or other congenital kidney abnormalities. It’s also sometimes used in prenatal screening or if you’re considering genetic counseling.

What to Expect Before the Test

You’ll provide a small sample of whole blood, usually drawn from your arm. This is similar to a regular blood draw. No special preparation is needed, but tell your doctor about any medications or health conditions you have before the test.

What the Results Mean

The test looks for specific genetic mutations linked to kidney development issues. If mutations are found, they may explain why you or your child has kidney problems. Results can help guide treatment plans, such as monitoring, surgery, or specialized care.

Common Conditions This Test Helps Diagnose

This screening can help diagnose conditions like renal dysplasia (underdeveloped kidneys), renal agenesis (missing kidneys), or other structural kidney abnormalities caused by genetic mutations.

Clinical interpretation

Frequently asked questions

How often will I need this test?
This test is typically done once as part of a diagnostic evaluation. If mutations are found, further testing or genetic counseling may be recommended to understand the full impact on your health.
What if my test results are positive?
A positive result means you or your child may have a genetic mutation linked to kidney development issues. Your doctor will work with you to discuss next steps, which may include additional genetic testing, monitoring, or referrals to specialists like a pediatric urologist or genetic counselor.
Can this test be done during pregnancy?
Yes, this test can sometimes be done during pregnancy if there’s a suspicion of kidney-related birth defects. It’s usually performed on fetal cells collected through procedures like chorionic villus sampling (CVS) or amniocentesis, but the whole-blood version is also used in some cases for genetic screening in newborns or at-risk individuals.
