[IPk] Urine testing for kidney function

Hi Di,

The urine dipstick is the least specific test of kidney function. It is the 
cheapest and quickest, though! By the time you have protein in your urine 
there is considerable damage done to the kidneys. Nephrology researchers 
live in hope that new markers of kidney function may be discovered in the 
blood because changes to urine composition are more often mid-stage 
complications of kidney disease.

The top clinical recommendation for early detection of microalbuminuria, 
which precedes overt proteinuria by a rather long lead-time, is a 24-hour 
urine collection for urinalysis in a laboratory. If your clinic has never 
ordered this for you and seems reluctant to do so, get a referral to a 
nephrologist. As you were diagnosed with kidney issues several years ago, it 
would not be out of order for you to have a 24-hour urine collection test 
once per year. For those with no signs of kidney trouble it can be done once 
every 2 years, but once a year is not too often after several years (7+) of 
diagnosed diabetes.

The single strongest predictor of mortality in type 1 diabetes is kidney 
function. The health of the eyes and the health of the kidneys are very 
closely related in many of us. I have heard some cutting edge doctors 
suggest that everyone who is diagnosed with retinopathy have a 24-hour urine 
collection test once yearly following the diagnosis of retinopathy.

Hope this is helpful, though it's not happy news....
