What is indicated if redness occurs on the patch after the sleeve test?

Redness occurring on the patch after the sleeve test indicates a normal physiological response to the laser treatment. When tissues are exposed to laser therapy, especially with Class IV lasers, a mild inflammatory response can occur, which often manifests as erythema (redness) in the treated area. This response is a sign of increased blood flow and is typically a part of the healing process, indicating that the body is responding to the stimulation of the cells and tissues.

In this context, redness is expected, especially when utilizing therapeutic laser modalities that aim to promote healing and reduce pain and inflammation. It is important for practitioners to recognize that such responses can be beneficial and part of the desired effects of laser therapy. Understanding this helps clinicians gauge the effectiveness of the treatment and the patient's reaction to it. This is distinct from other adverse reactions such as an allergic response or overdosage of the laser, which would generally present with other symptoms or require different management strategies.
