Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. WebHaemophilus parainfluenzae strains synthetize porphobilinogen and porphyrins, which are detected in the test. Porphyrins show characteristic red fluorescence when exposed to long wave UV-light (360 nm). Porphobilinogen that contains a pyrrole ring produces a red colour with Kovacs' reagent (92031) (in the lower water phase).
