9795. Амілоїд А (SAA, сироватка)
Important information
*The test is performed at Synevo laboratory in Germany
Description
Amyloid A (SAA) is an acute-phase protein whose serum level increases in response to inflammatory processes in the body. Its concentration rises under various pathological conditions but is not specific to any particular disease.
SAA levels increase earlier than C-reactive protein and respond equally to both viral and bacterial infections. SAA test results should be interpreted in the context of the overall clinical picture, accompanying symptoms, and other laboratory findings to avoid misinterpretation.
When and who needs the test?
Testing is advisable for patients with chronic inflammatory, infectious, or oncological diseases to assess disease activity and detect the risk of amyloidosis in time. It is particularly important when renal or other organ dysfunctions – targets of amyloid deposition – are present.
Patients with chronic inflammatory diseases:
- rheumatoid arthritis;
- ankylosing spondylitis (Bechterew’s disease);
- familial Mediterranean fever and other autoinflammatory disorders;
- systemic scleroderma; systemic vasculitis.
- Individuals with prolonged infections: tuberculosis; osteomyelitis; chronic purulent processes.
- Patients with malignant diseases (lung, kidney, ovarian, endometrial cancer, melanoma).
- Patients with signs of internal organ involvement, especially with suspected amyloidosis.
