MY purpose in presenting this article is to report briefly my experiences with the Aschheim-Zondek test for pregnancy which I had the opportunity of observing last winter in the laboratories of the Jewish Hospital of Brooklyn, New York. | |||

==Need of a Dependable Test== | |||
There has long been a want for a desirable and dependable laboratory test for pregnancy. Erdheim and Stumme} pointed out that during pregnancy marked changes in the histologic structure of the anterior lobe of the pituitary gland take place. Smith and Engle 2 and Evans and Long 3. demonstrated that the injection of anterior lobe of the pituitary gland into mice and rats caused marked enlargement of the ovaries. Aschheim and Zondek,‘ confirmed these observations and discovered that during pregnancy there was a striking overproduction of the hormone of anterior lobe of the pituitary gland, leading to its excretion in the urine. They also found that the subcutaneous injection of urine of pregnant women into immature female mice was followed by striking alterations in the ovaries, manifested by swelling, congestion, hemorrhage, and the premature maturation of the ovarian follicles. These changes were easily visible to the naked eye. Louria and Rosenzweig 5 carried out this test in one hundred and thirty-two cases. Eighty-seven specimens came from women in all stages of pregnancy and showed a positive reaction in 98 per cent. For controls they used the urine of nonpregnant women, among which were the urines from patients with fibroid uterus, ovarian cysts, functional amenorrheas, as well as normal women in the premenstrual and postmenstrual epochs and in the menopause. Specimens of urine from males were also injected for controls. These showed a negative reaction in 91 per cent. | |||

==The Aschheim-Zondek Test== | |||
The Aschheim-Zondek test is performed on female white albino mice, ranging in age from four to six weeks, their weight averaging about fifteen grams. Three-tenths of a cubic centimeter of urine is injected subcutaneously three times a day for three days. The injections should be at least three hours apart, although they can be separated by more time. It is best to use a rustless needle for the injections.

The earliest case of pregnancy examined was in a woman whose menstrual period was seven days overdue.

I have had no personal experience with the Aschheim-Zondek test of pregnancy, but in July of 1928 had the opportunity of meeting doctors Aschheim and Zondek and watching their work at the Charité Frauenklinik in Berlin, wh-ere the test was perfected. At this clinic I saw Professor Wagner operate upon a case under a diagnosis of left broad ligament fibroid and prove the preoperative diagnosis. This diagnosis had been made because of a negative test for pregnancy in the face of a typical textbook history_ of extra-uterine pregnancy. This case shows the reliance placed in the test at that clinic. Similar results were being found at the clinics in Vienna, where all who had undertaken the test were enthusiastic about it. | |||
In Berlin I was given the following figures by Doctor Aschheim: | |||
The test was positive for pregnancy four times in two hundred and fifty—eight nonpregnant cases. In thirty—two cases of five to six weeks’ pregnancy thirty were positive, and two were negative; in thirty-six cases of seven to eight weeks’ pregnancy thirty-six were positive, and none were negative; in one hundred and three cases of three to ten months’ preg nancy one hundred and one were positive, and two were negative; in twenty-six cases of unknown duration of pregnancy twenty-six were positive, and none were negative; or four negative reactions in one hundred and ninety-seven cases of pregnancy which equals two per cent errors. | |||

This percentage of ‘error is so small as compared with the Abderhalden and other serum reactions for pregnancy that it seems we can at last discard the older methods. The reliability of the test and the ease with which it can be done makes it possible for every hospital or commercial laboratory to furnish us a quite accurate diagnosis of early pregnancy in the puzzling case. The technique described by Doctor Kaplan is the _same as that used by Aschheim and is much more easily executed than the Abderhalden or any other serum test with which I am familiar. The only diflicult part of it is having female white mice at three to four weeks of age just at the time when the test is to be made, since immature mice must be used. The observations can be made with or without the aid of a microscope, which is time-saving as a laboratory procedure. | |||
