OVERVIEW:
What is the renal biopsy for H/P and (immunofluorescence and light microscopy) lab test?
A renal biopsy for H/P and (immunofluorescence and light microscopy) lab test is a laboratory procedure that extracts a small amount of kidney tissue and evaluates it to discover the presence and extent of any disease.
Why is the renal biopsy for H/P and (immunofluorescence and light microscopy) lab test done?
A renal biopsy for H/P and (immunofluorescence and light microscopy) lab test is done in order to:
- Determine how well a transplanted kidney is working,
- See if a kidney tumor is benign or malignant,
- Analyze the extent of kidney damage/failure,
- Help guide the treatment of a kidney disease,
- Determine the cause of proteinuria (high level of protein in the urine) and hematuria (blood in the urine).
INTERPRETATION OF THE RESULT:
The results of a renal biopsy are considered abnormal if there are changes in the kidney tissue. There are numerous causes for this result. Sometimes, diseases that begin in other parts of the body can cause damage to the kidneys.
If results are abnormal, it indicates:
- kidney infection
- restrictions or weaknesses in the flow of blood to the kidneys
- connective tissue diseases
- rejection of a kidney transplant
- kidney cancer
- complicated urinary tract infection
- numerous other diseases that have a negative effect on kidney function
WHY GET TESTED?
Renal biopsy is performed:
- To determine an abnormal level of waste products in the blood
- To see if a kidney tumor is malignant or benign
- To determine how well a transplanted kidney is working
- To investigate the cause of hematuria (blood in the urine)
- To determine the cause of proteinuria (high level of protein in the urine)
- To see the severity of progressive kidney failure and how quickly the kidneys are failing
- To create a treatment plan for a diseased kidney
