Effective April, 2004
Qualitative Critical Results
• Positive results from Gram stain or culture from blood and cerebrospinal fluid.
• Herpes simplex virus, group B Streptococcus, Listeria, or Neisseria gonorrhea from a neonate.
• New findings of blasts (possible leukemia) on a peripheral blood smear.
• Transfusion reaction workup with evidence of an acute reaction
• Red blood cells that were issued on an emergency basis and later found to be incompatible.
Important Findings Called to the Clinician
• Viruses isolated from any site
• Herpes simplex virus, group B Streptococcus, Listeria, or Neisseria gonorrhea from an obstetric or postpartum patient
• Initial positive AFB smears and cultures
• Positive Clostridium difficile toxin assay
• Parasites isolated from stool or other body site.
• Enteric pathogens from stool.
• Clostridium perfringens from any site
• Initial positive body fluid cultures (i.e. synovial, pericardial, etc) or peritoneal dialysis cultures from outpatient.
• Positive Cryptococcal antigen test.
• Patient has an antibody that would delay transfusion or surgery
• Blood order can’t be filled due to unavailability of component in question.
• Positive direct Coombs (AKA Direct Antiglobulin Test or DAT) on cord blood.
NOTE: Referral laboratory test critical values are as defined by reference laboratory, unless designated differently by the PAMC medical staff.
