The short answer

Several Georgia Nephrology offices have on-site labs. Your doctor will order labs — the blood and urine tests that track how your kidneys are doing — to be completed about one week before your appointment, so your results are ready to review when you're seen. That means your visit is spent going over real numbers, not waiting on them.

At a glance

  • About a week ahead Labs are completed before your appointment, so results are ready at your visit.
  • The key tests Blood for eGFR & creatinine; urine for protein (uACR).
  • Built for CKD Convenient for conditions that need labs again and again.
  • Several offices On-site labs at select metro-Atlanta locations.
  • Hours vary Some labs close for lunch — check the office page.
  • Usually no fasting Most kidney tests don't require it — we'll tell you if yours does.

Why testing in one place makes kidney care easier

Kidney care runs on regular testing. A few simple blood and urine tests are how your nephrologist sees what your kidneys are doing, catches changes early, and knows whether a treatment is working — and many kidney conditions call for those tests again and again over time.

That’s exactly why our on-site labs matter. Your doctor will order labs to be completed about one week before your appointment — a quick stop at an office with a lab — so that when you’re seen, your results are already in your nephrologist’s hands and your visit is spent reviewing what they mean.

American adults has chronic kidney disease — and most don’t know it, because early on it’s silent. A simple blood and urine test is the only reliable way to find it.

For someone managing chronic kidney disease, diabetes, or high blood pressure — conditions that need labs on a schedule — having a familiar lab inside your kidney office, with results flowing straight to your care team, genuinely adds up.

The kidney tests that matter, in plain language

Kidney lab work can look like a foreign language — eGFR, creatinine, uACR, potassium. It’s simpler than it seems. Two numbers tell most of the story, backed up by a handful of others.

eGFR
How well you filter

A blood test (based on creatinine, your age, and sex) estimating how much blood your kidneys clean each minute. 90+ is normal; below 60 for three months points to kidney disease.

↑ Higher is better
uACR
Whether protein is leaking

A urine test for albumin, a protein healthy kidneys keep in the blood. Finding it in urine is one of the earliest signs of damage — often before eGFR drops.

↓ Lower is better

Around those two, your nephrologist usually looks at a few more:

  • Creatinine — a waste product your muscles make that healthy kidneys clear; a high level is what makes eGFR fall. It’s the blood value eGFR is calculated from.
  • Electrolytes — potassium & sodium — minerals the kidneys help balance. Potassium in particular is watched closely, because levels that climb too high can affect the heart.
  • Hemoglobin — checks for anemia, which is common as kidney disease advances because struggling kidneys make less of the signal that tells the body to build red blood cells.
  • Urinalysis — a broader look at the urine for blood, protein, and other clues to what’s going on.

Two numbers do most of the work: your eGFR (how well you filter) and your uACR (whether protein is leaking). Ask for both at every visit.

If you want to go deeper on what these results mean, our guides on chronic kidney disease and protein in the urine walk through the numbers in detail.

How lab testing works around your visit

The rhythm is simple. Your nephrologist orders the labs that make sense for you, and about a week before your appointment you stop by an office with an on-site lab for a quick blood draw and urine sample. By the time you’re seen, your results are in — so the appointment itself is spent going over what they mean and what happens next.

A few practical things people ask about:

  • Fasting is usually not needed for kidney function tests. If your visit also checks things like cholesterol or blood sugar, we may ask you to fast — and we’ll tell you ahead of time.
  • Results come back quickly — routine kidney labs are often processed within a day or two, so completing yours about a week ahead means everything is ready well before your appointment.
  • Testing repeats on a schedule that fits you. People with diabetes, high blood pressure, or known kidney disease are typically tested one or more times a year so your team can watch for trends, not just a single snapshot.

Tracking your numbers over time is what reveals the real picture — whether your kidney function is steady, and whether your treatment is doing its job. An in-office lab makes keeping up with that schedule far less of a chore.

Georgia Nephrology has on-site labs at the following metro-Atlanta offices — where you can complete the labs your doctor orders before your appointment:

Each office’s location page lists its lab hours, which can differ from office hours (some labs close for lunch). If your office doesn’t have a lab, your doctor will order your labs at a nearby Georgia Nephrology lab office before your appointment. To find the office nearest you with a lab, find a location and check its page, or call 404-645-7150 and we’ll point you to the right one.

Why Georgia Nephrology

Care and testing in one place.

We've cared for metro Atlanta since 1976 — 19 physicians across 9 offices, with on-site labs at several. For people managing a long-term condition that needs labs again and again, that convenience adds up fast.

Because our labs are in our own offices, your samples are drawn about a week before your appointment and the results flow straight to your nephrologist — so when you're seen, your visit is spent reviewing what the numbers mean, not waiting for a callback.

Frequently asked

Common questions.

What tests does a nephrologist order?

Usually a blood test for kidney function (eGFR and creatinine) and a urine test for protein (the urine albumin-to-creatinine ratio, or uACR), along with a blood pressure check. Blood work often also looks at electrolytes like potassium and sodium, and sometimes hemoglobin to check for anemia. Depending on your situation, your nephrologist may add a kidney ultrasound or, in select cases, a kidney biopsy.

What is the difference between eGFR and creatinine?

They're related. Creatinine is a waste product your muscles make that healthy kidneys clear from your blood — a high level suggests the kidneys aren't filtering well. eGFR (estimated glomerular filtration rate) is a calculation that turns your creatinine, age, and sex into an estimate of how well your kidneys filter. With eGFR, higher is better; 90+ is normal and below 60 for three months points to chronic kidney disease.

What does the urine albumin (uACR) test show?

It measures albumin — a protein healthy kidneys keep in the blood — against the creatinine in your urine. Finding albumin leaking into the urine is one of the earliest signs of kidney damage, often appearing before eGFR drops. Under 30 is normal, 30–300 is moderately increased, and over 300 is severely increased. Lower is better.

Do I need to fast for a kidney function blood test?

Usually not — most kidney function tests don't require fasting. If your nephrologist is checking other things at the same time, like cholesterol or glucose, fasting may be requested. We'll always tell you in advance if you need to fast for any test.

How long do kidney lab results take?

Routine kidney blood and urine results are commonly back within a day or two, and some are available even sooner. Your nephrologist reviews them and contacts you, or goes over them at your next visit, with what they mean and any next step.

How often should I have my kidneys tested?

It depends on your health. If you have diabetes, high blood pressure, or known kidney disease, your nephrologist may check your eGFR and urine protein once or several times a year to watch for trends. People at higher risk are tested more often. Your team sets a schedule that fits your situation.

When should I get my labs done before my appointment?

About one week before. Your doctor will order the labs you need; completing them roughly a week ahead gives the lab time to process everything, so your results are ready to review at your appointment. If you're unsure where or when to go, call 404-645-7150.
