filter it into the urine. When creatinine rises in the blood, it often signals reduced kidney function. In the Swedish analysis, people in the top two creatinine quintiles had lower odds of reaching 100. That fits the broader link between kidney health and survival. Mild reductions in kidney filtration can appear with age, dehydration, or medications. Persistent elevations deserve evaluation, since they may reflect chronic kidney disease. On the liver side, higher quintiles of enzymes like gamma-glutamyl transferase, alkaline phosphatase, and lactate dehydrogenase were tied to lower odds of exceptional longevity. These enzymes can rise with liver or bile duct problems, alcohol use, certain medications, or other conditions.Consult Online Doctors
Doctors read these markers together, not in isolation. The study also noted a U-shaped link for aspartate aminotransferase. Both very high and very low values are related to lower odds. That pattern tells us extremes can be risky for
