GFR Full Form

GFR Full Form

The full form of GFR is the Glomerular filtration rate. It is the volume of fluid filtered from the renal (kidney) glomerular capillaries per unit time.  It is a measure of the kidney’s ability to remove wastes and excess fluid from the blood.

Types of GFR

There are three types of Glomerular Filtration Rate:

– Macroalbuminuria (GFR >30ml/min): This type of GFR is indicative of significant kidney damage

– Microalbuminuria (GFR30-300ml/min): This type of GFR is indicative of early kidney damage

– Normoalbuminuria (GFR 90-120 ml/min): This type of GFR is indicative of no kidney damage

Purpose of GFR

Glomerular filtration rate (GFR) is a measure of how well the kidneys filter blood. It tells us how much fluid and wastes the kidneys are removing from the blood. GFR is a calculation that uses your creatinine level and age to estimate how well your kidneys are functioning.

A GFR of 60 or higher is in the normal range. A GFR below 60 may mean kidney disease. If your GFR falls below 15, you have severe kidney failure and need dialysis.

GFR Meaning

GFR can give us important information about how well our kidneys are functioning. GFR can help detect kidney disease at an early stage and determine how quickly it is progressing.

Normal Range for GFR?

The normal range for GFR is 60-120 ml/min. A GFR of 60 or higher is in the normal range.

Things that can affect GFR

Some things that can affect GFR include:

-Age: As a  person gets older, their GFR tends to decline

-Gender: Men tend to have a higher GFR than women

-Race: African Americans tend to have a lower GFR than Caucasians

-Body size: People who are taller and have more muscle tend to have a higher GFR

-Diabetes: People with diabetes tend to have a lower GFR

-High blood pressure: High blood pressure can damage the kidneys and reduce GFR

-Heart disease: Heart disease can reduce blood flow to the kidneys and reduce GFR

-Kidney disease: Kidney disease can reduce GFR

-Liver disease: Liver disease can reduce blood flow to the kidneys and reduce GFR

-Exercise level: People who are physically active tend to have a higher GFR

-Smoking: Smoking can damage the kidneys and reduce GFR

-Alcohol: Heavy alcohol use can damage the kidneys and reduce GFR

Measurement of GFR

GFR is measured by a blood test. The test measures the level of creatinine in your blood. Creatinine is a waste product that is produced by muscle metabolism. It is filtered from the blood by the kidneys and excreted in the urine.

GFR test 

A GFR test is used to help determine how well your kidneys are functioning. The test measures the amount of a waste product called creatinine in your blood. Creatinine is produced when muscle tissue is used. The higher the creatinine level, the less well your kidneys are working.

Your doctor may order a GFR test if you have signs or symptoms of kidney disease, such as:

– Swelling in your legs or feet

– High blood pressure

– Protein in your urine

– Kidney stones

A GFR test may also be ordered if you’re taking medication that can affect your kidneys.

Performance of GFR test 

The GFR test is performed by drawing blood from a vein in your arm and sending it to a lab for analysis. The test measures the level of creatinine, which is a waste product produced by the body, in your blood. If you have a high creatinine level, it means that your kidneys are not filtering your blood properly.

Average GFR rate per age

As per the age the GFR rate averages are as follows-

90 mL/min/173 m² up to age 30

60 mL/min/173 m² at 31-60 years

30 mL/min/173 m² at 61-90 years

15 mL/min/173 m² over 90 years.

Glomerular filtration rate (GFR) is the volume of fluid filtered from the renal cortex per minute. Glomerular filtration rate (GFR) is considered an index of renal function. It can be affected by age, body size, gender, race, and other factors.

Conclusion

Glomerular filtration rate (GFR) is an important measure of kidney function. In this article, we’ve explained what GFR is, how it’s calculated, and some factors that can affect it. The test detects the amount of creatinine, a waste product, in your blood. When muscle tissue is utilised, creatinine is generated. The greater your creatinine level, the less efficient your kidneys are. We hope you found this information helpful and informative.
