I don't need a lab test to disprove transubstantiation. The taste test works well enough.
You tell me, what does it taste like? Human flesh or baked wheat?
Ahem, that's Mrs. Murphy, Mr. Murphy is my husband.
This statement indicates you really don't know what transubstantiation means. I suggest you read about it before you reject it. Unless you think you can get by with, "but nobody told me" when you face Our Lord at your judgment. You may not believe this, but I say this in all charity.
Bzzt! Wrong answer. Transubstantiation can not be proven or disproven by any test on the elements themselves. This includes senses or scientific insturments (which are but extensions of our senses).
You obviously do not understand the teaching. If you care to learn about it, there are ample resources available. If you desire to remain ignorant, that is your own choice. At least we know what we are dealing with now.

Tastes like wheat.
And Whom do I receive? Jesus Christ Our Lord.
I know you don't believe this. Fine. In John 6 it says that most of His hearers walked away from Jesus when he said, "Unless you eat my fleshand drink my blood, you do not have life within you." (The whole chapter bears careful reading.)
When the crowds left Him, did He chase after them saying, "Oh, come ON folks, Geez! It's just a metaphor!"?
John 6:66 After this many of his disciples turned back and no longer walked with him. 67 So Jesus said to the Twelve, Do you want to go away as well?
