Instructions for use

1. 1 — Cut the glove

   Cut a piece measuring at least 3 × 3 cm from the suspected glove. For a disposable glove, prepare a new piece for each night if possible.

2. 2 — Mark out an area of healthy skin

   On the inner forearm, choose skin without eczema or a wound and draw a square matching the size of the glove piece.

3. 3 — Apply the glove piece overnight

   At bedtime, place the inside surface of the glove against the skin and secure it with the tape or device indicated by the team. Leave it in place for about 6 to 8 hours, then remove it in the morning.

4. 4 — Repeat on the same area

   Unless your doctor gives different instructions: apply once every night for 10 consecutive nights, always to the same area. For a reusable glove, follow the instructions provided by the team.

How is the GRAT interpreted?

A positive GRAT supports the glove’s responsibility but does not identify the responsible chemical on its own. Patch tests, including an appropriate rubber series, remain useful. A negative GRAT makes the glove less likely to be responsible but does not always rule it out completely.
