- Quantitative, non-subjective results
- Increased sensitivity and broader detection range compared to rapid tests
- Working range: 15–35000 pg/mL
- Intra-lot Precision: Intra-lot precision was determined by testing of NT-proBNP reference materials using 10 test devices from the same lot. CV ≤ 15%.
- Inter-lot Precision: Inter-lot precision was determined by testing of NT-proBNP reference materials using 30 test devices from 3 consecutive lots randomly (10 test devices from each lot). CV ≤ 15%.
- NT-proBNP control materials with two different concentrations were tested by every lot of test device, and the deviations were within ±15%.
- A serial concentration of NT-proBNP reference materials at 15–35000 pg/mL was tested, and the correlation coefficient (R) is ≥0.9900.
