Welcome back. Case 37 has focused around an abnormal APTT. This is a common finding in the routine coagulation screen. It is important to investigate appropriately to avoid delayed procedures and patient anxiety. The first case had a factor XII deficiency and the second case was contaminated with heparin.
You are reviewing the results of a patient who has been admitted via the emergency department. She has type II diabetes and has been admitted with community acquired pneumonia. Results reveal:
- PT 14s (11-14s)
- APTT 48s (33-40s)
- Fibrinogen (Clauss) 4.9g/L (1.5-4.5g/L)
- Based on the previous cases how do you approach this problem?
- Should she receive prophylactic LMWH?
