Question: 1 / 400

A positive Kleihauer-Betke test indicates what in a traumatically injured patient?

Imminent delivery

Fetal blood is in maternal circulation

A positive Kleihauer-Betke test is indeed indicative of fetal blood in maternal circulation. This test is specifically designed to detect the presence of fetal hemoglobin in the maternal blood, which can occur when there is a fetal-maternal hemorrhage. In the context of a traumatically injured patient, a positive result suggests that fetal blood cells have entered the maternal bloodstream, which could be a sign of significant injury or trauma to the placenta or fetus. This information is critical for managing the care of both the mother and the fetus, as it may indicate potential complications requiring immediate medical intervention.

Understanding the correct application and interpretation of the Kleihauer-Betke test is crucial for healthcare professionals, particularly those involved in trauma care or obstetrics, allowing them to make informed decisions about patient management in acute trauma situations.
