Why is C3 low in glomerulonephritis?
Low C3 and C4 are characteristic of the glomerulonephritis caused by deposition of circulating immune complexes (e.g. SLE, infective endocardi- tis). Normal or nearly normal C3 with very low C4 is characteristic of type 2 and type 3 cryoglobulinemia.
What is low C3 and C4?
Low levels of C3 associated with low levels of C4 demonstrate classical pathway activation and strongly suggest immune complex disease. They are found most commonly in cases of active SLE.
What is the causative agent of glomerulonephritis?
Glomerulonephritis can be caused by various of factors including: Toxins or medicines. Viral infections, such as HIV, hepatitis B and C viruses. IgA nephropathy. Lupus-related kidney inflammation.
What is the pathogenesis of acute glomerulonephritis?
Acute glomerulonephritis (GN) comprises a specific set of renal diseases in which an immunologic mechanism triggers inflammation and proliferation of glomerular tissue that can result in damage to the basement membrane, mesangium, or capillary endothelium.
What is C3 kidney?
The “C3” refers to a blood protein that plays a key role in normal immunity and in the development of this disease. More on this later. The “G” is for glomerulopathy, meaning damage to the glomeruli in the kidney. Glomeruli filter your blood to get rid of toxins and make urine.
What is normal C3 level?
The normal range is 88 to 201 milligrams per deciliter (mg/dL) (0.88 to 2.01 g/L). Note: Normal value ranges may vary slightly among different laboratories. Talk to your provider about the meaning of your specific test results.

What did the Doctor mean by glomerulonephritis?
What did the doctor mean by glomerulonephritis? Glomerulonephritis (gloe-mer-u-low-nuh-FRY-tis) is inflammation of the tiny filters in your kidneys (glomeruli). Glomeruli remove excess fluid, electrolytes and waste from your bloodstream and pass them into your urine. Glomerulonephritis can come on suddenly (acute) or gradually (chronic).
What are the causes of glomerulonephritis?
Glomerulonephritis is a kind of kidney disease. It involves damage to the glomeruli, tiny filters inside your kidneys. It’s caused by a variety of things, from infections to problems with the immune system.
