How long does it take to get the results of a kidney biopsy?
In renal biopsy tests, the results are usually available in approximately four to five days after the examination, while some may be delayed to six to seven days. After renal biopsy, electron microscopy examination is required, and the results of such examination take about two weeks to emerge, providing a clearer understanding of the type and severity of kidney lesions.
The results of renal biopsy are typically available in about one week. Some hospitals may provide earlier results in 4-5 days, while others may take longer, up to 6-7 days. This is because processing the biopsy specimen requires some time. After biopsy, the specimen needs to be fixed using materials like formalin and glutaraldehyde, which takes a certain amount of time. Then, the specimen undergoes dehydration, usually by placing it in an automatic dehydration machine overnight, and the process continues until the next morning.
Renal biopsy is the gold standard for diagnosing kidney diseases. By obtaining pathological tissue and performing corresponding processing, it can provide clinical diagnostic information or detailed differential diagnosis. If the specimen is in good condition and the staining process is normal, the light microscopy results are usually available in about 5-7 working days after renal biopsy. The timing of electron microscopy results depends on the capabilities of each facility, typically taking approximately 15 working days. By combining the results of light microscopy and electron microscopy, doctors can comprehensively assess the severity of kidney pathology and formulate treatment plans based on clinical manifestations, which is conducive to the treatment and recovery of the disease.
