The Minor test (also known as Minor's test, the starch–iodine test, and the iodine–starch test), described by Victor Minor in 1928,[1] is a qualitative medical test that is used to evaluate sudomotor function (perspiration or sweating).[2]
Method
Tincture of iodine is applied to the skin and allowed to air-dry. After drying, the area is dusted with cornstarch or potato flour. Sweating is then encouraged by increased room temperature, exercise, use of a sauna, or pilocarpine.[2]
When sweat reaches the surface of the skin, the starch and iodine combine, causing a drastic color change (yellow to dark blue), allowing sweat production to be easily seen.[2]
Some have reported higher sensitivity and fewer drawbacks marking dry skin with water-erasable ink and observing fading.[3]
Uses
The Minor test can be used as a diagnostic tool to evaluate underactive (hypohidrosis)[4] and overactive (hyperhidrosis) sweating. This test can also reveal Horner's syndrome.[2]
