That’s good. I mean, I only had 2 tests done years apart on Tara, the last one a few years ago (she died on the cusp of 12yo).
As to mold, there are many. Black mold is a killer. But there are many kinds, and the tests should have many of them included.
We had a weekend house on Galveston Bay and I started having massive headaches after spending one night there. Turns out we had black mold inside most of the interior walls. The a/c unit in the attic leaked into the walls and they were full of black mold that we didn't know was there until it came through the sheetrock. I have had some bad allergy and migraine headaches but the mold headaches were the worst. My husband would have to carry me out of that house. It was the height of the mold hysteria but I am here to tell you for some of us it was bad. It never bother my husband even a little bit.
