Hi Lisa, Our God is an awesome God, abounding in love full of grace and mercy, and there is nothing he can't do. Youre on the right track.
Father, I lift up Eric to your care, and ask that you would be with him during the tests and that you would allow the tests to come back negative. Father I ask that you would grant peace to Eric and Lisa's hearts about this. Lord, we seek your will in this, that you will be praised above all and that your spirit will move upon these two through all of this. Thank you Lord for this answered prayer and for bringing them to a closer relationship with you. Thank You Father, all praise and glory are yours forever and ever. Amen
