| Kidney | Gamma-glutamyl transferase (GGT), Lactate dehydrogenase (LDH) | Renal injury, Tubular dysfunction |
| Bone | Bone-specific alkaline phosphatase (BALP) | Bone diseases, Metabolic bone disorders |
Looking at isoenzyme levels in organs is a powerful way to diagnose diseases. It helps doctors spot and track a variety of conditions. This includes heart issues, liver problems, kidney damage, and bone diseases.
“The distribution of isoenzymes across different organs is not just a fascinating biological phenomenon, but a critical component of effective clinical diagnostics and patient care.”
Doctors use molecular markers and biochemical diagnostics to understand isoenzyme distribution. This leads to more accurate diagnoses and better treatment plans for patients.
