Urine albumin testing
Albumin is a protein normally retained in the bloodstream by healthy kidneys.
When the kidney's filtering structures are damaged, albumin may leak into the urine.
A urine albumin-to-creatinine ratio can help identify this type of kidney damage, sometimes before a substantial decline in filtration becomes apparent.
The two tests provide different but complementary information. A person may have evidence of kidney damage even when their eGFR is relatively preserved.
According to the U.S. National Institute of Diabetes and Digestive and Kidney Diseases, people with diabetes, high blood pressure, heart disease, or a family history of kidney failure should discuss appropriate testing with their healthcare provider.

People at risk should not wait for symptoms before asking whether screening is appropriate.
14. Seven Practical Ways to Protect Your Kidneys
Although not every case of kidney disease can be prevented, several measures can reduce risk and help slow disease progression.
1. Keep blood pressure under control.
Monitor your blood pressure as advised and take prescribed medication consistently. If readings remain high, discuss them with your healthcare professional rather than adjusting treatment yourself.
2. Manage blood sugar if you have diabetes.
Follow your diabetes care plan and attend recommended kidney screening appointments. Early identification of kidney changes can help guide treatment.
3. Eat a balanced diet.
Choose a variety of vegetables, fruits, whole grains, and appropriate sources of protein. Limit excessive sodium and avoid making extreme dietary changes based on unverified claims.
4. Stay physically active.
Regular physical activity can help support blood pressure, weight management, cardiovascular health, and blood sugar control. Choose activities that are suitable for your fitness level and medical conditions.
5. Avoid tobacco.
Smoking increases cardiovascular risk and can worsen the overall health profile of people vulnerable to kidney disease.
6. Use medication responsibly.
Discuss frequent painkiller use, supplements, and herbal products with a healthcare professional. Follow directions for prescribed medicines and seek advice during illnesses that cause significant fluid loss.
7. Get tested when appropriate.
If you have diabetes, hypertension, cardiovascular disease, or a family history of kidney failure, ask how often you should have kidney function and urine albumin checked.
These measures have a stronger foundation in kidney health guidance than relying on a single food or drink to prevent disease.
15. Should You Stop Drinking Coffee After Reading This Story?
For most healthy adults who enjoy coffee and tolerate it well, an alarming online story alone is not a reason to stop drinking it.
Current observational evidence does not establish that moderate coffee consumption causes chronic kidney disease. Some studies have instead found associations between coffee consumption and more favorable kidney outcomes.
However, these findings should not be interpreted as a reason to drink more coffee for kidney protection.
Coffee is not a treatment for kidney disease, and drinking it cannot compensate for uncontrolled diabetes, high blood pressure, smoking, or other significant risk factors.
The appropriate choice depends on your overall health.
If you have uncontrolled blood pressure, significant caffeine sensitivity, certain heart conditions, or an established kidney disorder, discuss your intake with your healthcare professional.
If you enjoy coffee, consider keeping your portions reasonable, limiting added sugar, and paying attention to its effects on sleep and blood pressure.
If you do not drink coffee, there is no need to start drinking it to protect your kidneys. Many of the most effective ways to maintain kidney health have nothing to do with coffee at all.
16. The Bottom Line: Do Not Let One Headline Replace Medical Evidence
The story of a 50-year-old man reportedly diagnosed with end-stage kidney failure after years of drinking coffee is a reminder that kidney disease can affect people in midlife and may remain unnoticed until it becomes advanced.
But the story, by itself, cannot establish that coffee caused his condition.
Research involving large populations has generally found no evidence that ordinary coffee consumption universally increases the risk of chronic kidney disease. Some observational studies have even associated coffee consumption with a lower risk, although researchers have not established that coffee itself is responsible for the difference.
The more important priorities are to recognize established kidney disease risk factors, manage blood pressure and blood sugar, use medications responsibly, and obtain appropriate screening.
Remember that kidney disease can develop without obvious symptoms. If you have diabetes, high blood pressure, heart disease, or a family history of kidney failure, ask your healthcare professional whether you need regular blood and urine tests.
For most people, coffee can remain part of a balanced lifestyle when consumed in an amount appropriate to their individual circumstances.
The goal is not to fear every cup of coffee. It is to make informed decisions, recognize the limits of online health stories, and focus on the habits and medical care that have the clearest role in protecting kidney health.
