Abstract
AIM: FibCare(®) is a novel point-of-care testing device enabling prompt evaluation of fibrinogen levels. This study aimed to investigate the accuracy of FibCare(®) at a tertiary emergency department. METHODS: Blood specimens obtained at a tertiary emergency medical center between October 1, 2021, and April 30, 2023, were evaluated. The correlation between the fibrinogen levels assessed via FibCare(®) and those via the Clauss method was evaluated using the Spearman's test. The discrepancy between the two measurement methods was assessed according to fibrinogen level and diagnosis. RESULTS: A total of 177 specimens from 147 patients were eligible for the analysis. The median age of the patients was 49 years, and 109 (61.6%) were men. The two measurements had statistically significant but moderate correlation (p < 0.001, ρ = 0.76). FibCare(®) missed 14 out of 35 cases from patients with hypofibrinogenemia (fibrinogen ≤150 mg/dL assessed by the Clauss method). The discrepancy between the two measurements was significantly greater in specimens with lower fibrinogen levels and those obtained from patients following trauma. CONCLUSIONS: FibCare(®), a novel point-of-care testing device, can be compatible with the Clauss method. However, clinicians should be aware of the risk that FibCare(®) may underestimate fibrinogen reduction, especially in severe cases and trauma cases.
