Cystatin C is a low-molecular-weight protein that is produced by all nucleated cells in the human body at a constant rate. Unlike traditional renal function markers such as creatinine, its concentration is not affected by factors like muscle mass, age, or gender, making it a more accurate indicator of glomerular filtration rate (GFR). Our Cystatin C Assay Kit is designed to provide rapid, precise, and high-throughput detection of Cys-C levels in human biological samples. It has become an essential tool for clinical laboratories, hospitals, and research institutions focused on renal disease diagnosis and management. This kit is optimized for both manual and automated operation, ensuring broad applicability across different testing scenarios.

The kit adopts latex-enhanced immunoturbidimetry technology, which significantly improves the binding efficiency between antibodies and Cystatin C antigens. It can accurately detect trace amounts of Cys-C in samples, avoiding false positive or negative results caused by cross-reaction with other proteins.
The kit requires minimal sample pretreatment steps. It only takes 10 minutes to complete a single test cycle. It is suitable for both small batch manual testing and large batch automated testing, effectively improving laboratory testing efficiency.
All raw materials of the kit are strictly screened and undergo multiple rounds of quality verification. The test results show excellent consistency across different batches. It can meet the strict requirements of clinical diagnosis and scientific research for data accuracy.
Elevated Cystatin C levels are closely associated with early-stage renal damage diseases such as nephrotic syndrome, early diabetic nephropathy, and hypertensive kidney damage. The kit can help clinicians identify renal function abnormalities at an early stage, providing a basis for timely intervention.
After kidney transplantation, the kit can continuously monitor the dynamic changes of patients’ Cystatin C levels. It can quickly assess whether the transplanted kidney is functioning normally, helping to detect rejection reactions at the earliest opportunity.
For patients undergoing long-term hemodialysis, regular detection of Cystatin C levels can evaluate the efficacy of dialysis treatment. It guides the adjustment of dialysis plans to ensure optimal treatment outcomes for patients.
Our Cystatin C Assay Kit complies with ISO 13485 quality management system standards. Every production link is subject to real-time monitoring and inspection. The qualified rate of finished products reaches 100%.
We provide one-stop technical services including pre-sales consultation, on-site installation and debugging, and after-sales maintenance. Our professional team responds to customer questions within 24 hours to ensure smooth use of the products.
We can customize the kit’s packaging specifications, detection range, and compatible instruments according to the specific needs of customers. It meets the personalized testing requirements of different laboratories.
The kit is suitable for human serum and plasma samples. Plasma samples are recommended to use EDTA or K2-EDTA as anticoagulants. Avoid using heparin anticoagulant, as it may interfere with the test results.
The kit should be stored at 2–8℃, away from freezing and direct sunlight. Do not mix different batches of kit reagents. After opening, the reagents should be used up within 30 days under the recommended storage conditions.
Yes. The kit is compatible with most mainstream automatic biochemical analyzers on the market. It supports high-throughput testing of up to 200 samples per hour, which is very suitable for large-scale clinical laboratories.
