🩺 CLINICAL INTEGRATION OF KFT & LFT IN PRACTICE
- Neurology → If a patient presents with confusion, always check LFT (Ammonia, Bilirubin) to rule out hepatic encephalopathy.
- Rheumatology → In autoimmune conditions, both KFT & LFT should be monitored for multi-organ involvement.
- Toxicology → Acetaminophen overdose affects both liver & kidneys, requiring early intervention with NAC & dialysis.
