Your Partner for Early Kidney Disease Detection

Early kidney disease detection supports better coordination across the care journey. Timely, accurate insight into kidney function enables earlier intervention and helps reduce long-term complications. 

 

Ascend supports these efforts with clinically relevant testing and a laboratory experience built for clarity and consistency. 

 

We offer key markers used in CKD detection, assessment and monitoring, including creatinine, cystatin C, eGFR with creatinine-cystatin and renal function panel testing. Every kidney disease lab test we perform is supported by advanced automation and standardized processes, allowing us to deliver dependable results at scale.

eGFR + Creatinine

eGFR is used for assessing filtration status and staging CKD. We use the 2021 CKD-EPI Creatinine-Cystatin equation to support CKD evaluation and long-term monitoring.


Creatinine remains a core marker in renal assessment and routine monitoring. When reviewed alongside eGFR and other kidney markers, it helps support a more complete interpretation of renal status over time.

Albumin/Protein + Urinalysis

Urine albumin and protein testing help identify early kidney damage and stratify renal risk. These markers are particularly valuable in CKD screening, progression monitoring and diabetes-related kidney care.


Urinalysis can provide clinical context when evaluating kidney health and related abnormalities in the urine. Ascend offers urinalysis with reflex to microscopic examination, giving providers additional information that can support assessment and broader renal care management.

Electrolyte Panels

Our renal function panel includes sodium, potassium, chloride, CO2, glucose, BUN, creatinine, calcium, phosphorus and albumin. Together, these analytes help clinicians monitor metabolic balance and complications that can influence ongoing kidney disease management.

Frequently asked questions

Common chronic kidney disease diagnostic tests include creatinine, eGFR, urine albumin-creatinine ratio (uACR) and renal function panel testing. Providers may also use cystatin C and eGFR with creatinine-cystatin to support evaluation and ongoing monitoring.

 

A kidney profile can also simplify ordering by grouping recommended tests for evaluating both kidney function and kidney damage.
