The Albert Stain is a critical, time-sensitive test used to rapidly identify the bacteria that cause Diphtheria, a serious respiratory infection. This test is performed on a simple throat swab collected by your doctor. In our lab, we apply the special stain, which allows our microbiologists to see the characteristic, 'beaded' appearance of the Diphtheria bacilli under a microscope. While a culture is needed for final confirmation, this rapid stain is the essential first diagnostic step. It provides the fast, preliminary answer your doctor needs to make critical, time-sensitive treatment decisions.
