The VA tests veterans with, or without HCV, for creatinine levels:
The level of creatinine in your body is a marker of kidney function. Creatinine comes from the breakdown of creatine, a muscle protein. Properly functioning kidneys remove creatinine from the blood….If your creatinine level is too high, you may not be able to receive hepatitis C treatments.
The VA also tests the Glomerular filtration rate which the National Kidney Foundation say is an accurate test:
Glomerular filtration rate (GFR) is the best overall index of kidney function. Normal GFR varies according to age, sex, and body size, and declines with age. The National Kidney Foundation recommends using the CKD-EPI Creatinine Equation (2009) to estimate GFR.
There is a lot of good information on the NKF website including calculators, check lists, and risk assessments and more. I’ve been unable to download their pdfs or even copy and paste the URLs, but there is a link to read information on this page, FAQ, Click here.
The VA employs many nephrologists which is reassuring to me tonight because I checked my spouse’s most recent lab results that were just posted on myhealthevet; he may actually have a kidney problem. He has an appointment with his primary next week so he’ll be asking for an interpretation of the results. Will report back if he receives any helpful guidance. As always, your experiences/knowledge with any conditions you chose to share here will be read with appreciation.
