Albert Stain
Albert Stain
The Albert stain test is used to identify the bacterium Corynebacterium diphtheriae in swab samples taken from patients. These samples are then analyzed in a suitable laboratory setting through a microscope.
Diphtheria is a severe bacterial infection that primarily affects the mucous membranes in the nose and throat. This infectious disease can be effectively managed through the use of medications. However, in more severe cases, diphtheria can damage vital organs such as the heart, kidneys, and nervous system.
Thus, it is recommended to get this test done for the timely identification of Corynebacterium diphtheriae. Early detection plays a pivotal role in the prompt management of the disease
