fat fecal test

Hi my question (was long) just got lost in space!!
Okay asked Dr. for fat fecal test, he suggesested also doing test for parasite's,
which I thought were like never proven in US??  He said he "did" give me fat test
he gave me 2 paks which say ova and parasite on them, the third says Para-Pak C&S
for Culture and Sensitivity)  non nutritive stool transport for enteric pathogens??

And just one blank one that I have to Freeze?

Can any of the last two be for Fat testing???

Anybody who had this please feel free to give me some feedback!!

Hoping CalGal or JayBay might know..............thanks...........Denise

The stool tests for parasites are very 'proven' in the U.S. and are routinely used. The Para-Pak is for Campylobacter jejuni, Giardia lamblia and other parasites (in group), and
Salmonella spp. and Shigella spp. The other test pack probably tests for a variety of other parasite forms.

Do you have a name on the one you have to freeze? There are a lot of different test kits for a variety of things that have to be frozen. So without a name it would be difficult to tell you if that's the one for fat or not.
