[2025-10-01T00:26:32.880550] [PI reasoning] **Analyzing prolonged TT conditions**

I'm examining why TT is prolonged even with normal fibrinogen and platelets. TT can lengthen due to low or dysfunctional fibrinogen, or inhibitors like heparin. The key is understanding that normal fibrinogen might mean quantity but could still be functionally abnormal (dysfibrinogenemia). Liver disease could cause this, producing abnormal fibrinogen and leading to prolonged TT while platelets remain normal initially. So, it seems the most likely answer is "Liver disease." Let's double-check that.
