SAA Serum Amyloid A Test Kit 3 Minutes Rapid Test Clinical
Significance
SAA Overview
Serum amyloid A (SAA) is an acute-phase-reactive protein that is
secreted by the liver.When viral or bacterial infection occurs, SAA
increases significantly within 3 to 6 hours, which can increase
hundreds of fold in the acute phase.The SAA has a short half-life
and decays rapidly during recovery.It is more sensitive than the
CRP.The combination of the two can better distinguish between
infection types and improve the diagnostic efficiency of viral
infection.

Clinical Significance Of SAA
Dynamic monitoring
Prognosis evaluation
Guiding medication
| Virus infection sensitivity index | The SAA is more sensitive than the CRP.Combined detection of CRP
with SAA contributes to the detection of early infectious disease. |
| Transplant rejection test indicators | It have shown that SAA is one of the early indicators of rejection
as a sensitive indicator for early detection of graft rejection. |
| Monitoring indicators of tumor invasion and metastasis | SAA has been elevated to varying degrees in patients with various
tumors, and its levels are significantly associated with tumor
activity, malignancy, invasion, and metastasis, and can be used as
one of the indicators of dynamic monitoring |
| Predictors of cardiovascular events | Increased SAA concentrations are positively correlated with the
likelihood of future cardiovascular events in healthy people, so
SAA can serve as a predictor and prognostic indicator of
cardiovascular events. |
| Diagnostic indicators of AA amyloidosis | SAA is a precursor to AA and plays a key role in the
pathogenesis.Long-term maintenance of serum SAA levels at high
concentrations can be used as an indicator of treatment and SAA
prognosis |
