Tenant claiming mold present - Help!

[Dan Barth]

Hey Guys,

I have a tenant in Philadelphia who a few months back mentioned that she feels more tired than usual and wanted to test for mold. It was very vague/general request, in which I gave her the okay to purchase test kits online and do her own test. She put 3 test kits throughout the place this past week and each one had a few specs of mold - see pictures below/attached. Since specs of mold showed up, she wants me to have a professional inspect for mold.

back story on the unit - This tenant (1 of 2 girls) is moving out end of july and the other tenants boyfriend will be taking her place until the end of the lease (end of August). The building is 60+ years old, in which there is no evidence of visible mold, no mildew smell.

I was going to offer to have the testing done but tell the tenant that if the results show no harmful mold, the cost would come out of her security deposit.

Any thoughts or suggestions on how this should be handled?
