The case here described is of interest and importance because it represents a limited group of tubal gestations in which tests for pregnancy yield negative reactions. It brings to attention, also, a limitation of the pregnancy test infrequently set forth in the literature.
An intricate diagnostic problem arose in connection with a patient with a suspected tubal abortion. The classic clinical evidence was not present. Two tests for pregnancy gave negative results, and since curettings revealed no decidual reaction, laparotomy was delayed for thirty-five days. The reason for the inadequacy of the test in this instance is clearly illustrated by the pathologic findings. Consideration of this factor is therefore of utmost value in the diagnosis of tubal abortion.
