Wear Time

The PharmChek® Sweat Patch is designed to be worn a minimum of 24 hours, which ensures enough sweat is absorbed into the pad to be tested at the laboratory.

The maximum wear time for the patch is 7 to 10 days, or up to 14 days for some clients with the use of our optional overlay.

The client can perform normal activities such as bathing, showering, participation in sports, or swimming. The PharmChek® Sweat Patch should receive the same degree of care that one would take with a conventional bandage. When drying after a shower or bath, blot the patch, do not rub the towel over it.
