Answer

Visible signs of hyperhidrosis are clearly evident. If direct visualization of the affected areas by hyperhidrosis is desired, the iodine starch test may be used. This test requires spraying of the affected area with a mixture of 0.5-1 g of iodine crystals and 500 g of soluble starch. Areas that produce sweat turn black.
