Procalcitonin has several advantages over CRP and ESR as a biological marker. Serum concentrations of PCT are normally <0.05 ng/mL. Procalcitonin levels become detectable within 3–4 hours and peak within 6–24 hours, which is earlier than both CRP and ESR.
16 maj 2024 · This topic presents a discussion of the biology of the acute phase response; the general clinical utility and interpretation of measurement of APR, such as CRP; and the clinical utility of indirect measures of the acute phase response, such as the erythrocyte sedimentation rate (ESR) and CRP.
The aim of this report is to address the issue of when, if ever, it is appropriate to concurrently test ESR and CRP (as opposed to testing only ESR or CRP) to help diagnose inflammatory disease or serious infection.
4 maj 2023 · However, neither study directly compared CRP vs PCT performance. Additional data is needed to compare CRP vs PCT for antibiotic initiation or cessation in other LRTI, such as pneumonia, and in the inpatient setting.
10 paź 2019 · For the diagnosis of other various inflammatory conditions, CRP had a superior diagnostic accuracy, with a Se of 0.86, Sp of 0.67, and SAUC of 0.86 compared with a Se of 0.77, Sp of 0.59, and SAUC of 0.75 for ESR. Heterogeneity among studies was elevated.
29 kwi 2019 · The objective of this study was to evaluate the prognostic value of C-reactive protein (CRP), procalcitonin (PCT), and their combination for mortality in patients with septic shock.
Objective: A thorough understanding of the similarities and differences between these two serological markers, including factors that affect measurements, is necessary for the proper utilization and interpretation of ESR and CRP.
