Frequently Asked Questions
What kidney labs should I ask for?
The basic kidney panel includes serum creatinine, BUN, and eGFR. A complete metabolic panel (CMP) adds sodium, potassium, calcium, and CO2. For a more thorough check, ask about urine albumin-to-creatinine ratio (UACR), phosphorus, and hemoglobin.
How often should I get kidney labs?
If you have no kidney disease: annually as part of routine check-ups. CKD Stage 1-2: every 6-12 months. CKD Stage 3: every 3-6 months. CKD Stage 4-5: every 1-3 months, or as directed by your nephrologist.
What does high creatinine mean?
High creatinine usually means your kidneys aren't filtering as well as they should. However, it can also be temporarily elevated from dehydration, intense exercise, high-protein diet, or certain medications. One elevated reading doesn't necessarily mean kidney disease — your doctor will want to confirm with repeat testing.
What is BUN and why does it matter?
BUN (Blood Urea Nitrogen) measures urea, a waste product from protein metabolism. High BUN can indicate kidney problems but is less specific than creatinine — it's also affected by diet, dehydration, heart failure, and some medications. Doctors typically look at the BUN-to-creatinine ratio for additional diagnostic information.
