Inflammation of kidney tissue that may be caused by gout or disorders affecting calcium balance.
Because ratings are built around GFR measurements, lab records are the most direct evidence. VA accepts GFR, estimated GFR (eGFR), and creatinine-based GFR approximations when a medical professional calculates them. Records showing GFR readings taken at least 3 months apart — and spanning the past 12 months — help establish whether your kidney function meets a sustained threshold.
For the 0% level, urinalysis results showing recurrent red blood cell casts, white blood cell casts, or granular casts are relevant, as are imaging or pathology reports documenting structural kidney abnormalities. Lab reports showing an albumin/creatinine ratio of 30 mg/g or above, sustained for at least 3 consecutive months, also support that level.
If you are on dialysis, records documenting the dialysis schedule and frequency support the 100% level. If you have received or are awaiting a kidney transplant, documentation of your transplant eligibility or procedure supports that level as well. Statements from treating physicians explaining how your kidney function has changed over time can help connect the lab values to the rating criteria.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
