CompuNet Laboratory Critical Values

Premier Pulse     January 2020

CompuNet has an established Critical Values policy as defined by Dr. Ronald Chiu, CompuNet medical director. The critical values list has been set for lab results that may pose an immediate health risk or require a provider’s attention. Currently, communication priority levels have been set based on the level of urgency.

P1:  The highest level of urgency is Priority 1. If a patient’s lab result falls within the “P1” category, the lab will contact provider 24 hours a day, seven days a week.

P2:  Priority 2 results are considered less urgent and the lab will contact the provider during the hours of 9 a.m. to 5 p.m., seven days a week.

P3: Priority 3 results are considered the least urgent; however, a provider will be called by the lab if a patient has a “P3” result from 9 a.m. to 5 p.m., Monday through Friday. Providers will not be paged for “P3” results.

Please note that when CompuNet undergoes its lab information system conversion to Sunquest in April 2020, the priority notification levels will be adjusted.
