Are You Experiencing Unusual Symptoms?

Have you noticed puffiness around your eyes, fatigue that doesn't go away, or changes in how often you urinate? While these can be caused by many factors, they may also signal that your kidneys are under strain.

What Exactly Are Creatinine and eGFR?

Your kidneys are vital for filtering toxins from your bloodstream. Creatinine is a natural waste product, and tracking its level in your blood can reveal how well your kidneys are working. Alongside this, the eGFR offers a more comprehensive assessment by considering your age, sex, and ethnic background.

If any of these sound familiar, it’s worth understanding the science—and having an easy way to check where you stand.
