Good that you went to the doctor!
Tests are to find out if anything is wrong so they can fix it.
I'll pray for you, not the test, which I hope will reveal the truth.

Please pray this: "Dear Lord Jesus, thank You for dying on the Cross for me. Please come into my heart in a fresh new way and give me the ability to live as I should, a life that is pleasing to you. Grant me your peace, and let your shield of protection be over us all day and night. I have confidence in You, that You will be my Shepherd and provide what You see I need all the days of my life, as I live for You. Thank You, Lord Jesus, amen."

Pray that often, and read Psalm 23 and the final part of Romans 8 beginning with "If God is for us, who can be against us?"

Continuing to pray...
