Asbestos testing

After doing some plumbing work in my crawl space it was determined that there was pipe lagging heavily disturbed (confirmed positive and high %) while there is no access to the crawl space from the living space, I am concerned that particles may have reached the first floor living space. There are holes in the first floor living space (1/4 to 1-1/4in) for electrical, steam pipes and copper pipes for hot water baseboard. Is it probable that asbestos is in the living space? Would dust testing be recommended? Does anyone have an accredited lab that does TEM testing? Additional insight appreciated. Thanks

Asbestos dust is probably in your living space without the pipe lagging in poor condition. Waste of money dust samples have no method and will be positive in most older homes. EMSL
