Respiratory tract infection was the most common source of sepsis. PCT proved to be an excellent indicator of sepsis with sensitivity of 94%. There was a significant association between serum PCT and SOFA scores (P < 0.05). Serum PCT levels did not predict mortality in the present study.
The general rule of thumb is that one is supposed to arrive. 1  2 hours early for a domestic flight and. 2  3 for an international flight.
If your flight is at 6:30, and it's a domestic flight, you need to be there 2 hours ahead therefore the desk has to be open at 4:30 a.m....if it's written in the rules of the airline, it will have to happen. Ditto for 3 hours ahead for international flights.
