What a kidney function test is
Your kidneys filter waste out of your blood. A kidney function test measures a few markers that show how well they are doing that job. MedlinePlus says a creatinine test "measures creatinine levels in a sample of your blood and/or urine (pee)" (MedlinePlus, read 13 Nov 2026). Creatinine is a waste product that muscles make.
Labs often turn the creatinine number into an eGFR. MedlinePlus calls this an "estimated glomerular filtration rate (eGFR)," a calculation that also uses age and sex, and says eGFR and GFR tests "check how well your kidneys are working" (MedlinePlus, read 13 Nov 2026).
This page covers price and where to order. What a result means for you is a question for your clinician.
Kidney function test price by seller
Read from each seller's own page. Fee on top is what the seller adds beyond the list price.
| Test | Seller | Price | Fee on top | Read on | Source |
|---|---|---|---|---|---|
| Kidney Health Test (eGFR, creatinine, albumin, ACR) | Labcorp OnDemand | $109 | None shown | Nov 13, 2026 | Labcorp |
| Kidney Profile Test, Basic (creatinine, eGFR, albumin) | Quest Health | $110.00 | $6.00 physician service fee | Nov 13, 2026 | Quest Health |
| Kidney Profile Test, Expanded (adds cystatin C, urinalysis, CBC, CMP) | Quest Health | $200.00 | $6.00 physician service fee | Nov 13, 2026 | Quest Health |
ACR is the albumin-to-creatinine ratio, which compares a protein in urine to urine concentration. The tests are not identical, so read the list of markers on each page before you compare prices. We did not find a stand-alone cystatin C test on the pages we read, so we left other sellers out instead of guessing.
For the same store-by-store method on other tests, see the PSA test cost guide, the titer test cost guide and the no-insurance price hub.
Creatinine, eGFR and cystatin C
Creatinine and eGFR come together in most basic kidney tests. Labcorp says its test "checks for the level of creatinine, a waste product produced by muscles, to see how well the kidneys work." Quest's Basic page says it will "measure your blood creatinine, eGFR, and albumin levels that indicate your kidneys' ability to filter waste and toxins."
Cystatin C is a different marker. MedlinePlus describes it as "a protein that many cells in your body make" and says some researchers think it "provides a more accurate estimate of GFR than creatinine." Quest's Expanded page says it is part of a larger test that also includes a urinalysis, a blood count and a metabolic panel. Our CMP guide explains that panel.
Who can order it without a doctor
Both stores add a clinician review at checkout, so you do not need a doctor visit first. You then give a sample at a lab. Quest Health says collection is "not available in AZ, HI, or PR." Labcorp's page lists no excluded states, but state rules can change what a store sells where you live. Our state guide and ordering your own blood test explain the rules.
Quest asks you to avoid vigorous exercise for at least 24 hours before collection. Labcorp's page says the test must be taken by the purchaser.
Insurance, HSA and FSA
Lab stores sell at a self-pay price. Labcorp's page says the test is accepted for HSA and FSA. Our HSA and FSA guide covers what each seller says.
Questions
FAQ
How much is a kidney function test without insurance?
It depends on the markers included. Labcorp OnDemand lists its Kidney Health Test at $109. Quest Health lists its Basic profile at $110 plus a $6 fee. Both were read November 13, 2026.
How much is a cystatin C test?
The cystatin C test we found is part of Quest Health's Expanded kidney profile, listed at $200 plus a $6 fee on November 13, 2026. That profile also includes a urinalysis, a blood count and a metabolic panel. We did not find a stand-alone price.
What is an eGFR test?
An eGFR is an estimate of how well your kidneys filter blood. MedlinePlus says it is a calculation that uses your creatinine level along with factors such as age and sex. Most kidney tests in our table report it. A clinician can explain what your number means.
Is a renal function panel the same as a kidney profile?
Not always. Names vary by lab, and each seller chooses its own list of markers. The sellers in our table list creatinine, eGFR and albumin, and the Expanded profile adds more. Read the marker list on the product page before you buy.
What is the cost of a creatinine test?
Creatinine is included in the kidney tests above rather than priced alone on the pages we read. The Labcorp Kidney Health Test at $109 and the Quest Basic profile at $110 plus a $6 fee both include it, read November 13, 2026.
Can I order a kidney function test without a doctor?
Yes, through a lab-test store. Both Labcorp OnDemand and Quest Health add a clinician review at checkout, so no visit is needed. Quest does not offer collection in AZ, HI or PR. Share your results with your own clinician.
Does insurance cover a kidney function test?
Coverage depends on your plan and on a clinician ordering the test. Lab stores sell at a self-pay price, and Labcorp's page says HSA and FSA cards are accepted. See our HSA and FSA guide for details. Compare every seller on the price page or the best blood tests page.
