[Extrauterine pregnancy--the clinical experience of using a new differential-diagnostic immunological test].

The authors report results of immunologic test, that has been used to help the decision in some difficult for differential diagnosis cases. Two immunologic parameters were investigated--the amount of circulating immune complexes (CIC) and the lymphocytic nuclear coefficient (LNC). The results are put on a specially designed nomogram. The combined test used in the Department of "Obstetrics and Gynaecology"--Pleven, gives excellent results. The advantages of the test are discussed and a clinical case is presented as an illustration.
