Diabetic Kidney Disease (DKD) Serum

Diabetic Kidney Disease (DKD) Serum for Renal Biomarker Research

Our Diabetic Kidney Disease (DKD) Serum is sourced from IRB-consented donors clinically diagnosed with diabetic kidney disease, a progressive complication of diabetes and a leading cause of end-stage renal disease. Each sample is processed and frozen within 24 hours of collection to preserve circulating renal biomarkers and inflammatory mediators relevant to disease pathophysiology.

DKD Biology and Why Serum

  • Chronic hyperglycemia drives glomerular hyperfiltration, mesangial matrix expansion, and podocyte injury, producing progressive proteinuria/albuminuria and a gradual decline in estimated glomerular filtration rate (eGFR).
  • Serum is the standard matrix for clinical renal panels (creatinine, BUN, cystatin C) and is widely validated for KIM-1 and NGAL immunoassays used to detect tubular injury earlier than creatinine-based measures.
  • Low-grade chronic inflammation, reflected in circulating TNF receptor and inflammatory cytokine levels, is increasingly recognized as a driver of DKD progression independent of glycemic control.
  • Renoprotective therapies including SGLT2 inhibitors, GLP-1 receptor agonists, and the nonsteroidal mineralocorticoid receptor antagonist finerenone have shifted the treatment landscape, creating demand for biomarkers that track renal protection and disease-modifying response.
  • Disease staging by CKD stage and albuminuria category (A1/A2/A3) is central to both natural history and treatment-response research.

Are samples IRB approved?

1 Answer

YES – All collections are conducted under IRB-approved protocols and electronic informed consent. Sanguine utilizes Advarra and WCG IRB for oversight.

YES – all our products are research use only (RUO).

Storage depends on sample type but often cryopreserved samples stored in liquid nitrogen can be stored for years.

Extensive customization is available. To discuss your project request a quote or email us at learnmore@sanguinebio.com.

Sanguine offers flexible prospective collection services tailored to fit your research. For more information and to request a quote, please see: our prospective biospecimen collection services page.

Timelines depend on condition, sample type, and I/E criteria but we often start collection within 2 weeks of signed agreement.

YES – we have in-stock inventory. You can also email us at learnmore@sanguinebio.com as we continually get new samples in our inventory.

Each sample from a different individual – Unique donor means each sample comes from a different person, ensuring biological diversity in your study.

YES – Unique donors can be specified and guaranteed based on your requirements.

For information about sample quality, please see: Quality and Compliance

YES – “IRB-approved collection protocols” and IRB approval documentation available upon request. Sanguine utilizes two internationally-recognized IRBs (Advarra and WCG IRB) for review and approval.
