Cystatin C - PT. RAFA

 

Cystatin C

 What is Cystatin C?

Cystatin C is a protein that is produced by cells in your body. When your kidneys are working well, they keep the level of cystatin C

in your body at a consistent level. If the level of cystatin C in your blood is too high, it may mean that your kidneys are not working well.

A simple blood test for cystatin C can help

 

find your GFR (glomerular filtration rate).  The GFR gives a clear message to how well your kidneys are working.

Your kidneys are very important, they filter our waste whilst hanging on to the healthy components, help make red blood cells and keep

your bones strong. Cystatin C is extremely sensitive to very small changes in GFR and therefore capable of detecting early reductions in

GFR compared to the traditional creatinine test. Up to 50% of kidney function can be lost before significant creatinine elevation occurs!

However the cystatin C test does not suffer from the same creatinine ‘blind’ range, meaning loss of kidney function can be detected much

earlier resulting in early detection of kidney diseases.  

 

World Kidney Day - 9 March 2017

On March 9th it is World Kidney Day, and the theme this year is kidney disease and obesity. Obesity and being overweight are

risk factors for chronic kidney disease and are associated with the progression of the disease.  This highlights the requirement for

regular and accurate kidney function testing for these patients.  For further reading on the link between abdominal fat and kidney

function, check out our blog post ‘What is the relationship between kidney function and abdominal fat?’.
