Early kidney screening gains importance in diabetes management amid rising risks

Routine kidney screenings using tests like eGFR and urine albumin are crucial for early detection of damage in diabetes patients, with experts emphasising the need for regular monitoring to prevent progression to kidney failure.

Kidney disease is one of the most serious long-term complications of diabetes and high blood pressure because it can advance quietly for years before clear symptoms appear. That is why doctors stress routine screening: catching early changes can slow progression and reduce the risk of kidney failure. Mayo Clinic says people with diabetes should have regular urine and blood tests to look for early damage, while guidance from the Saudi Ministry of Health also places kidney checks among the core follow-up tests for diabetes care.

One of the key measures is estimated glomerular filtration rate, or eGFR, which is calculated from blood creatinine and helps doctors judge how well the kidneys are filtering waste from the blood. Creatinine alone is useful, but it is the eGFR estimate that gives a fuller picture of kidney function. The other main marker is urine albumin, which looks for protein leaking into the urine, a sign that the kidneys may be damaged even when a person feels well.

Doctors also often use the urine albumin-to-creatinine ratio, known as UACR, because it helps standardise the result from a single urine sample. According to the National Center for Biotechnology Information, an annual kidney screening is recommended for many people with diabetes, with testing starting at diagnosis for type 2 diabetes and about five years after diagnosis for type 1 diabetes. Its guidance also notes that both UACR and eGFR are central to spotting chronic kidney disease early.

Blood pressure control is another essential part of protecting the kidneys. The Indian Health Service says targets below 130/80 mmHg are important for many patients with diabetes, and it recommends ACE inhibitors or ARBs for those with hypertension and albuminuria, as these medicines can help delay the worsening of chronic kidney disease. Cleveland Clinic likewise emphasises regular follow-up, including urine checks for albumin and blood tests for filtration, because timely treatment is most effective before major damage has occurred.
