La trombofilia es una predisposición congénita o adquirida a sufrir un evento trombótico. El desarrollo de la trombosis se debe a un proceso multifactorial en el que pueden intervenir tanto causas genéticas como factores ambientales. Ante un paciente que ha presentado una trombosis es fundamental realizar una adecuada investigación de la historia personal y familiar, antes de considerar un análisis específico de trombofilia. El estudio de trombofilia se suele indicar en pacientes que han presentado un episodio trombótico sin un claro factor desencadenante.

Diagnostic protocol for thrombophilia: Thrombophilia is a congenital or acquired predisposition to having a thrombotic event. The development of thrombosis is a multifactorial process in which both genetic and environmental factors can intervene. When faced with a patient who has presented with thrombosis, it is essential to carry out an adequate investigation of the personal and family medical history before considering a specific analysis of thrombophilia. A thrombophilia test tends to be indicated for patients who have presented with a thrombotic episode without a clear triggering factor.
