The intensity and pattern of sweating can be made visible with a starch-iodine test.
The skin is brushed with a iodine solution. Starch powder is then applied. The sweat reacts with the componants and turns dark blue to black.
This test is useful to determine what area needs to be treated during sweat gland curettage or injection of sweat reducing medication. Sometimes this is limited to the hair-bearing skin while in other patients the dimensions are several centimetres larger.
