Uso excesivo de la prueba de ANCA
Keywords:
prueba de ANCA, anticuerpos frente al citoplasma del neutrófilo, vasculitis sistémica.Abstract
La desproporcional y alta frecuencia de órdenes médicas de anticuerpos frente al citoplasma del neutrófilo (ANCA, por sus siglas en inglés) dirigidas a nuestros laboratorios clínicos evidencia el sobreuso de la prueba de ANCA. El uso indiscriminado de esta aumenta los gastos sin beneficio de salud. El laboratorio clínico es el eslabón de la cadena diagnóstica que más siente el uso excesivo de las solicitudes de ANCA, básicamente porque genera resultados falsos positivos que comprometen la utilidad clínica de la prueba, además de recargar innecesariamente el trabajo diario del laboratorio.
