| Interpretive Data: |
Procalcitonin > 2.00 ng/mL:
Procalcitonin levels above 2.00 ng/mL on the first day of ICU admission represent a high risk for progression to severe sepsis and/or septic shock.
Procalcitonin < 0.50 ng/mL:
Procalcitonin levels below 0.50 ng/mL on the first day of ICU admission represent a low risk for progression to severe sepsis and/or septic shock.
If the procalcitonin measurement is performed shortly after the systemic infection process has started (usually less than 6 hours), these values may still be low. As various non-infectious conditions are known to induce procalcitonin as well, procalcitonin levels between 0.50 ng/mL and 2.00 ng/mL should be reviewed carefully to take into account the specific clinical background and condition(s) of the individual patient.
|
| Note: |
Procalcitonin levels below 0.50 ng/mL do not exclude an infection, because localized infections (without systemic signs) may also be associated with such low levels.
