Visual reading can only be used to determine approximate concentration of SAA.Presence of control line (C) indicates successful development of test.Two SAA capture lines increase in intensity with increased SAA in sample.Control line (C) will decrease in intensity when high quantities of SAA are present.
General guidelines for interpretation
Visual Interpretation of Serum Amyloid A (SAA) Test
<20 µg/mL ~100 µg/mL ~1000 µg/mL > 3000 µg/mL~50 µg/mL
normal<20 μg/mL
low moderate high very high3000+ μg/mL
Localized inflammation
Chronic inflammation
Viral infection
Bacterial infection
Acute systemic inflammation
peak SAA μg/mL
<20 µg/ml - No systemic inflammation (normal SAA).
20-100 µg/ml - May indicate primarily local process or developing/resolving systemic inflammation.
>100 µg/ml - Indicates likely systemic inflammation and possible infection.
