Abstract
Rapid lateral flow immunoassays have an extensive history of use in both the clinical and home settings. These devices are used to test for a variety of analytes, such as drugs of abuse, hormones, proteins, urine or plasma components and the like. The present invention provides an improved procedural control that indicates to the test user that at least a portion of the applied sample has passed through the test result zone of the test strip, and optionally that the test is complete and the test results may be read.
