How to Diagnose Red Skin Spots

Diagnosing red skin spots involves examining their appearance, distribution and any accompanying symptoms. Here's how doctors typically approach it:

Medical History: The doctor will ask about recent illnesses, allergies, new medications, insect bites or skin care products.
Physical Examination: The shape, size, location and texture of the red spots provide clues to the cause.
Allergy Testing: Patch tests or blood tests (like IgE levels) may be done if an allergic reaction is suspected.
Skin Biopsy: A small sample of skin may be taken for laboratory analysis in unclear or persistent cases.
Blood Tests: To rule out infections, autoimmune conditions or platelet disorders like in petechiae.
Dermatoscopy: A non-invasive skin examination using a dermatoscope helps evaluate moles, rashes or spots in detail.
