Medical Use
Although the starch-iodine test is predominantly employed in the lab, recent assessments have shown potential for clinical use, such as confirming the diagnosis of Horner's syndrome. Hospitals with limited technical accessibility can exploit this diagnostic tool since it requires resources that may be easily attainable. In order to perform the experiment, a patient's skin is first dried with 70% alcohol; with the iodine solution added, subsequently. After the skin dries completely once more, it will be dusted with a starch material. Inducing sweating conditions will cause the skin to turn dark blue. Physicians can then make a diagnosis if the test shows sweating of different intensities on the left and right side of the body.
