"New three routine tests", namely white blood cell (WBC)+ C-reactive protein (CRP)+ serum amyloid A(SAA), were proposed by A number of well-known pediatric experts in recent years based on the clinical value of SAA detection in the diagnosis of infantile infection, and have been widely used and recognized. The results showed that the total positive rate of SAA in various inflammatory diseases was 8.54% higher than that of CRP. Combined SAA and CRP tests allow for more accurate diagnosis of the type of infection and monitoring of the course of infectious disease
Detection range | sample size | Sample type | Test time | |
CRP | SAA | 5μl | Whole blood / serum / plasma | 3min |
0.5~200mg/L | 5~200mg/L |
SAA normal CRP was normal | SAA normal Elevated CRP | SAA increased CRP was normal | SAA increased Elevated CRP |
Consider non infectious factors | The disease is improving | Consider virus infection | Consider bacterial infection |
Continue treatment according to clinical symptoms or continue to monitor SAA, CRP until normal | Continue treatment according to clinical symptoms or continue to monitor SAA, CRP until normal | Antiviral therapy; Monitor SAA and CRP until normal or consider changing treatment plan | Antibiotic treatment, monitoring SAA, CRP to return to normal or consider changing treatment regimens |
