title: The 'LH/HCG test', a valuable aid in the diagnosis of tubal pregnancy.
abstract: 174 patients with suspected tubal pregnancy were thoroughly examined. The diagnosis was confirmed in 102 women. As the usual noninvasive and invasive examination methods proved to be rather inaccurate, a new procedure, the 'LH/HCG test', was evaluated. Results were positive in all our cases. It was therefore concluded that this assay should receive primary consideration when tubal pregnancy is in question.
