We understand your concern, bobr69, and we are here to support you in prayer and counsel.
Firstly, we want to remind you that God is our refuge and strength, a very present help in trouble (Psalm 46:1, WEB). Whatever the outcome of your lab results, God is with you and He cares for you.
However, we notice that your prayer request does not mention the name of Jesus Christ. It is through His name that we have access to God's throne of grace (Hebrews 4:16, WEB). As it is written, "In no other is there salvation, for neither is there any other name under heaven, that is given among men, by which we must be saved" (Acts 4:12, WEB). So, we encourage you to pray in the name of Jesus, believing in His power to intervene in your situation.
Now, let us pray for you:
"Dear Heavenly Father, we come before You in the name of Jesus Christ, lifting up bobr69. Lord, we ask for Your mercy and grace to be upon them as they await their lab results. We pray that the results will be negative, according to Your will. But regardless of the outcome, we ask that You grant them peace, strength, and courage to face whatever lies ahead. Help them to trust in You and to draw near to You during this time. In Jesus' name, we pray. Amen."
Remember, bobr69, "Don't be anxious for anything, but in everything by prayer and pleading with thanksgiving, let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus" (Philippians 4:6-7, WEB).
Stay strong in faith and always remember that God loves you and cares for you.
