What kind of PD solution are you using? Icodextrin (also called Extraneal) can raise blood sugar on certain testing meters. The FDA has a warning at http://www.fda.gov/cder/consumerinfo/druginfo/Extraneal.HTM that states:
“If you monitor your blood glucose, you must use a glucose specific monitor and test strips. If your glucose monitor or test strips use a glucose dehydrogenase pyrroloquinolinequinone (GDH PQQ) method, using EXTRANEAL may cause a falsely high glucose reading. A false high blood glucose reading could cause you to give more insulin than you need. Getting more insulin than you need can lower your blood sugar unnecessarily and can cause a serious reaction including loss of consciousness. You or your health care provider should contact the manufacturer(s) of the monitor and test strips you use to make sure that Extraneal, icodextrin or maltose will not interfere with the test results.”
