What is it indicated for?

The DialGuard™ device is intended to be used for the reduction of endotoxin from:

1. Dialysate prior to entering the dialyser

2. Water prior to its use for preparation of dialysate

3. Water prior to use for regenerating dialysers.

DialGuard™ is intended to be used on a regular preventative basis during hemodialysis treatments. Experimental data indicates that DialGuard ™ will consistently reduce endotoxin levels to € 0.05 EU/mL. (AAMI standard for water for dialysate is < 5.0 EU/mL. Currently, there are no standards set for dialysate).

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
