# R53\_EVALUATE\_TARGET\_HEALTH

`R53_EVALUATE_TARGET_HEALTH` lets you enable target health evaluation for a [`R53_ALIAS()`](/language-reference/domain-modifiers/service-provider-specific/amazon-route-53/r53_alias.md) record. Omitting `R53_EVALUATE_TARGET_HEALTH()` from `R53_ALIAS()` set the behavior to false.
