The C - reactive protein (CRP) is synthesized by the liver in response to interleukin- 6 and well known as one of the classical acute- phase reactants and as a marker of inflammation. The serum CRP level may rise from a normal level of < 5 mg/L to 500 mg/ L during the body’s general, non- specific response to infectious and other acute inflammatory events. High- sensitivity CRP (hsCRP) is also emerging as the strongest and most independent predictive risk factor for atherosclerosis and cardiovascular diseases (CVD). For people the diagnosis of inflammatory disease and CVD assessment cutoffs have been recommended as follows: STORAGE AND STABILITY 1. Store the detector buffer at 2～30℃. The buffer is stable up to 18 months. 2. Store Aehealth CRP Rapid Quantitative Test cassette at 2～30℃, shelf life is up to 18 months. 3. Test cassette should be used within 1 hour after opening the pack. PERFORMANCE CHARACTERISTICS Detection Limit: 0.5 mg/ L ; Linear Range: 0.5～200 mg/ L; Linear correlation coefficient R ≥ 0.990; Precision: within batch C.V. is ≤ 15%; between batches C.V. is ≤ 20%; Accuracy: the relative deviation of the measurement results shall not exceed ± 15% when the accuracy calibrator prepared by CRP national standard or 1.0mg/ Land 10.0mg/ L standardized accuracy calibrator are tested.
