The examination may include checking the skin and looking for bruising or bleeding elsewhere. Depending on the circumstances, testing may include:
A complete blood count to assess platelet levels and other blood cells
Blood-clotting tests
Additional blood tests or investigations guided by the symptoms and examination
Not everyone needs every test. The clinician decides which investigations are appropriate.
If a specific medication or medical condition is responsible, treatment will focus on that cause. For example, an infection may require targeted treatment, while a platelet or clotting disorder may need specialist assessment.
There is no single cream that treats petechiae themselves. Because the spots represent bleeding beneath the skin, treating the underlying cause is more important than treating the surface appearance.
Frequently Asked Questions
Are petechiae always dangerous?
No. Petechiae can occur after physical strain or for other relatively minor reasons. However, they can also signal serious infection, low platelet counts, or other medical conditions. New, unexplained, or spreading spots should be assessed rather than automatically dismissed.
