title: Five recent urinary tests for early pregnancy evaluated.
abstract: We evaluate five tests developed for the earlier detection of pregnancy, either in the clinical laboratory or by the patient in her home. These tests offer no advantage over other urinary pregnancy tests, and the results are distinctly inferior to those reported (Clin. Chem. 29: 561-563, 1983) for some serum tests for pregnancy.
