ABSTRACT:
The present invention relates to a diagnostic test kit and method for detecting the presence of certain metabolic by-products in human urine. The kit includes a test strip with an exposed face side containing chemical reagents which react in the presence of selected metabolic by-products. The reverse side of the test strip has an adhesive backing which allows the strip to be mounted in the interior of a commode bowl, initially above the water level. Flushing the commode causes the water level to rise and contact the chemical reagents. The reaction can be visually observed by removing the test strip from within the commode bowl.
