Kidney Testing

Overview of Kidney Test Functions

Regular kidney testing is crucial in maintaining optimal kidney health and detecting potential issues early on. During a routine check-up, your healthcare provider may order a series of kidney function tests to assess the health and functionality of your kidneys. These tests aim to measure various parameters that indicate kidney function and identify potential kidney diseases. The severity of these tests usually varies depending on the individual's medical history, risk factors, and symptoms.

Starting with the most basic test, a urinalysis examines a urine sample for the presence of protein, red blood cells, white blood cells, and other substances. Urinalysis helps identify early signs of kidney damage or infection.

Blood tests, such as serum creatine and blood urea nitrogen (BUN), are commonly performed. These tests assess the levels of waste products in the blood, typically filtered by the kidneys. Elevated levels may indicate impaired kidney function.

More specialized tests like glomerular filtration rate (GFR) estimation can provide a more accurate measure of kidney function. GFR measures how effectively the kidneys filter waste from the blood.

In cases where more severe kidney diseases are suspected, additional tests may be ordered. These may include imaging tests like ultrasounds or CT scans to evaluate the kidneys’ size, shape, and abnormalities. Biopsy, which involves extracting a small sample of kidney tissue for examination, may be conducted to diagnose the underlying cause of kidney dysfunction.

What Each Kidney Function Test Looks For?

 

What Each Kidney Function Test Looks For

Kidney function testing identifies potential kidney diseases and assesses the kidney’s overall health and performance. Below is an overview of what each kidney test looks for:

  • Urinalysis: This test checks for the presence of abnormal substances in the urine, such as Albumin, a protein that can pass into the urine when the kidneys are damaged.
  • Serum Creatinine and BUN: These blood tests measure waste product levels in the blood. Elevated levels suggest impaired kidney function or other kidney-related issues.
  • GFR Blood Test: Glomerular filtration rate estimates the kidneys' ability to filter waste from the blood. A low GFR may indicate reduced kidney function.
    Imaging Tests: Ultrasounds and CT scans provide visual images of the kidneys, helping identify abnormalities, such as kidney stones or tumors.
  • Kidney Biopsy: In some cases, a kidney biopsy may be necessary to diagnose specific kidney diseases by examining a small sample of kidney tissue.

Regular kidney testing is essential, as it allows healthcare professionals to detect kidney disease early on, monitor kidney function, and implement appropriate treatments to prevent further damage. Suppose you experience frequent urination, blood in urine, or persistent fatigue. In that case, scheduling an appointment for kidney testing is essential to maintaining kidney health.

Kidney Biopsy Procedure, Risks, and Recovery Time

Kidney Biopsy Procedure, Risks, and Recovery Time

A kidney biopsy is a medical procedure used to diagnose and assess kidney conditions and kidney disease. Kidney biopsies involve obtaining a small sample of kidney tissue for examination under a microscope. Kidney biopsy reasons may vary, though your healthcare provider may order a kidney biopsy for an unexplained drop in kidney function, chronic blood in urine, protein found in urine, or following a kidney transplant.

 

How Long Does a Kidney Biopsy Procedure Take?

A kidney biopsy is a medical procedure used to diagnose and assess kidney conditions and kidney disease. Kidney biopsies involve obtaining a small sample of kidney tissue for examination under a microscope. Kidney biopsy reasons may vary, though your healthcare provider may order a kidney biopsy for an unexplained drop in kidney function, chronic blood in urine, protein found in urine, or following a kidney transplant. 

During a kidney biopsy, two main techniques are commonly used: open biopsy and needle biopsy. An open biopsy is a more invasive procedure that involves making a small incision in the back or side to access the kidney directly. Open biopsies are performed under general anesthesia and the kidney biopsy procedure time can be from one to two hours. More commonly used is a needle biopsy or renal biopsy. Needle biopsies are minimally invasive and involve inserting a thin needle through the skin and into the kidney to collect the tissue sample. Needle biopsies are typically performed under local anesthesia and take approximately 30 minutes to an hour to complete. Kidney biopsies are generally safe, though risks include discomfort around the biopsy site, bleeding from the kidney, and infection.

What Are the Risk and Recovery Time After a Kidney Biopsy?

Depending on the kidney biopsy performed and your healthcare provider’s preferences, kidney biopsy procedure recovery time can vary. As the anesthesia wears off, you will be taken to a recovery room for observation and monitoring. You will be asked to lay on your back for several hours while a nurse checks for signs of bleeding. When your blood pressure, pulse, and breathing are stable you may be taken to a hospital room or discharged. 

Following a kidney biopsy, it is recommended to rest for 24 to 48 hours and limit physical activity. You should avoid strenuous physical activities for the first week following the procedure, avoiding activities like jogging, tennis, aerobics, and horseback riding. Depending on the physical requirements of your job, your healthcare provider may recommend taking two or more days off of work following the procedure. If you experience symptoms such as severe pain, persistent bleeding, or difficulty urinating following a kidney biopsy, you should immediately contact your healthcare provider.
