Laboratory tests for children IgA nephropathy:
Blood IgA assay: half the patient's blood IgA increases.
People with nephropathy can hae hypoalbuminemia and hypercholesterolemia, and kidney insufficiency and blood creatinine can be increased.
Urine routine: mostly urine. It is not difficult to find in the eyes of the naked eye, which is more than the examination or urine screening.
The differential diagnosis of IgA kidney disease should be distinguished from four types of pathologies:
Differential diagnosis of IgA kidney disease and purpura nephritis in children:
Purpura nephritis is also characterized by haematuria, but can be identified by the history of allergic purpura. The differential diagnosis can be diagnosed by renal biopsy when necessary.
Differential diagnosis of IgA kidney disease and lupus nephritis:
Lupus nephritis is characterized by microscopically or macroscopically, often associated with multiple systems. It is not difficult to identify the C3, antinuclear antibodies, lupus cells and renal biopsy.
Differential diagnosis of IgA nephropathy in children with hepatitis b virus:
In hepatitis b virus associated nephritis hematuria, accompanied by a large amount of proteinuria, but the disease had hepatomegaly and liver function abnormalities, HBsAg positive and/or HBeAg positive.
Differential diagnosis of IgA renal glomerulonephritis:
Acute glomerulonephritis is mainly characterized by haematuria, with edema and high blood pressure, and the blood is often increased rapidly, and the total complement and C3 often decrease significantly.
