Calculadora de Parathormona obtenida a partir de una analítica a valor de laboratorio. CONVERSIÓN PTHi A VALORES KDOQI/IRMA NICHOLS SEGÚN MÉTODO UTILIZADO "Válido solo para pacientes en diálisis" (No válido para paciente con ERC no en diálisis). La paratohormona es una hormona que produce hipercalcemia (aumento de la concentración de calcio en sangre) si hay un aumento en su secrección; por otro lado, su déficit produce hipocalcemia (bajos niveles de calcio en la sangre) y como consecuencia de esto, puede inducir a la tetania. Además, regula la concentración de iones calcio en el líquido extracelular, aumentando la resorción ósea al estimular a los osteoclastos para degradar el hueso, lo que libera más calcio al torrente sanguíneo. En el caso de iones calcio, lo que hace es aumentar la resorción proximal de estos iones procedentes del hueso, principalmente, para así aumentar los niveles de calcio en sangre. Por tanto, tiene un efecto contrario a la calcitonina. De igual forma, regula los niveles de iones fósforo en la sangre, de tal forma que hace descender la concentración de ellos en este medio al aumentar su excreción renal (hiperfosfaturia).
