What oil analysis companies do particle counts?

[LateArrivalforLSU]

I usually get my oil analysis done by Oil Analyzers, Inc., but I can't find any info. on their website that states they do particle counts. What companies do particle counts?

Thanks.

Blackstone does. It's a $20 test on top of the regular analysis.

OAI does particle counts, but they charge $40. I asked them once as I was curious myself.
