Blasto. hominis - questions for UK lab techs

I'm cross-posting again to sci.med.laboratory.

The lab you're referring to is probably Great Smokies Diagnostic
Laboratory. Did she see an MD over here or some other alternative
medical person? GSDL does a lot of work for the latter. I don't know
much else about them other than they're a very large laboratory that
does a lot of stool analysis.

I am not a physician and don't really know what to tell you regarding
treatment. That is not what I do for a living. As far as reporting
standards, I don't know what labs do in the UK. 

Has your mother seen an infectious disease doc?

Stools for O&P exam really should be collected directly into a
preservative kit. We supply two vials; one is 10% formalin, and the
other is PVA (poly-vinyl alcohol) to preserve the trophozoite stage. The
formalin is for the cyst stage of parasites. B. hominis can present from
specimen placed in either vial. I don't know how long they last in
unpreserved stool. Do your labs not provide for a preservative kit for
outpatients?

I know there are some UK techs on sci.med.laboratory. Anyone care to
comment on whether Blastocystis hominis is reported on O&P exams over
there?
