To explore the laboratory diagnostic characteristics and differential diagnostic approaches for fibrinogen Longmont, providing a reference for accurate interpretation of coagulation reports.
Approach:
Key Findings:
Optical FIB assays yielded falsely low results (<0.35 g/L) while magnetic bead assays provided normal results (4.18 g/L).
Fibrinogen Longmont was confirmed as the diagnosis, characterized by a genetic mutation affecting clot formation.
Interpretation:
The study highlights the importance of using multiple testing methodologies to avoid misdiagnosis of fibrinogen abnormalities.
Limitations:
The case study is based on a single patient, which may limit the generalizability of findings.
Variability in laboratory methods and reagents may affect the reliability of results.
Conclusion:
Accurate laboratory diagnosis of fibrinogen abnormalities is crucial.
