On Tuesday October 26, 2021, a new lot of aPTT reagent will go live for the Spectrum Health Laboratory Information System starting at 10:00 AM.

• The aPTT therapeutic range for ADULT patients on continuous heparin infusions will be updated to reflect the new reagents.  The therapeutic range, for most indications, will be changed from 37 to 52 seconds to a new range of 42 to 57 seconds.
