Requisitions accompanying the Urine specimens

The requisitions accompanying the urine specimens indicate that all three require a UA. Rosa performs the physical analysis and notes that Mrs. Carpenter’s urine, which requires the pregnancy test, is amber, whereas the other two specimens are pale yellow. What are possible explanations for Rosa’s observations? Should Rosa be concerned about the darker color of Mrs. Carpenter’s urine? Should she document this in the patient’s electronic health record (EHR) so that Dr. Hill is alerted?
