Before tearing it out you will need a way to get good ventilation in and out. You'll also need a mold rated respirator.
No way to live in it while mold work is going on.
You could pick up a mold test kit in the paint department of HD or similar. They are probably under $10. You may not wish to send to a lab for testing, but the amount of growth in the petri dish will confirm or deny the presence of mold. Afterb that, if you want, you can send it to the lab listed on the paper and for about $50 they will tell what kind of mold and in what amounts.
You can also PM questions if you want. I hold a FL mold remediators license.
