Other Diagnostic Studies
Finger Probe Test
- Finger probe test is useful in the diagnosis of necrotizing fasciitis.[1]
Procedure
- This test is carried out in the ward, emergency room and in the theatre under local or general anesthesia.
- After infiltrating the area, a 2cm incision is made down to the deep fascia.
- Fascia will be swollen and grey on gross inspection.
- Gentle probing with index finger is performed at the level of deep fascia and if the tissue dissects with the minimal resistance, then finger probe test is considered positive.
- Signs suggesting necrotizing fasciitis include:
- Lack of bleeding
- Lack of normal tissue resistance on finger probe
- Oozing of malodorous "dish water fluid"
