Critical / Panic Value Policy
Critical/Panic values are defined as values that are outside the normal range to a degree that may constitute an immediate health risk to the individual or require immediate action on the part of the ordering physician. It is the policy of the clinical laboratory to call the critical values listed to a licensed provider as soon as completed and verified in compliance with hospital policies approved by the Lucile Packard Children's Hospital and Stanford Health Care hospital boards of directors. Read back of the critical values by the person receiving them to the person making the notification call is required.
