title: A new, more sensitive tube test for pregnancy evaluated with a selected hospital population.
abstract: A new tube test for pregnancy, having a sensitivity of 0.5 I.U. of human chorionic gonadotropin per milliliter, was evaluated, along with two other commercially available kits, in a hospital patient population. Of 586 patients in the study, 302 were in nonobstetric services and many were acutely ill. Approximately one fourth of the women were age 40 or older. The medical records of 66% of the patients were retrieved to obtain information on the drugs administered prior to pregnancy testing. A small number of problems did occur in the pregnancy test procedures. Inconclusive results were recorded for both pregnant and nonpregnant patients and could not be correlated with disease states and/or medications. The importance of a reagent control for tube test procedures is discussed.
