Reference range
This result is reported qualitatively or as a one-sided threshold rather than a two-sided numeric band.
Combined adult band. LabVals does not publish separate men's, women's, or pediatric ranges for Procalcitonin; those can be narrower than the band shown.

What is the normal range for Procalcitonin?
The standard teaching reference range for Procalcitonin is < 0.10 (bacterial infection unlikely) ng/mL in conventional units, or < 0.10 µg/L in SI units. This value is measured in serum or plasma.
Source: Adult reference values compiled from Pagana & Pagana, Mosby's Diagnostic and Laboratory Test Reference, and Fischbach & Dunning, A Manual of Laboratory and Diagnostic Tests. Reference ranges vary by laboratory, method, age, sex, and population - always use the range printed on the actual result.
Helps distinguish bacterial from viral infection and can guide antibiotic decisions.
