Re: [Histonet] PAS stain for nail fungus
you have the South Texas Toenail lab guy right here. That's why I'm known as
"Joe the Toe".
We soak our nails in 20% ammonium hydroxide for at least an hour before
we put the blocks on the machine to process. We've been getting nailed for a
couple of years and perform a PAS for Fungus on each case that we do.
Reimbursement must be good, we keep getting nailed.
Joe the Toe or just JTT
