ABSTRACT:
A diagnostic means and method of testing for pregnancy in humans and a test kit incorporating such diagnostic means and ancillary materials. A sample of a patient's first morning urine is added to a test tube containing a known lyophilized reagent. The tube is capped, shaken to mix the contents, and placed upright for one to two hours. The tube is then inverted and compared with positive and negative standard vials to show either agglutination of particles, such as red blood cells, contained therein, in which case the subject is not pregnant, or a failure to agglutinate, in which event the patient is pregnant. The test tube is of sufficient dimension to support capillary action and is formed from, or has its interior surface coated with, a material which is non-wettable to the liquid contained therein.
